|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

&lt;br /&gt;
after that install playonlinux&lt;br /&gt;
&lt;br /&gt;
== Get more fps in games ==&lt;br /&gt;
Change your cpu profile to performance:&lt;br /&gt;
&lt;br /&gt;
cpufreq-set -g performance&lt;br /&gt;
&lt;br /&gt;
This change is not permanent, to make it permanent write this line to /etc/rc.local before &amp;quot;exit 0&amp;quot; . If needet install the cpufreq package first.&lt;br /&gt;
&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..&lt;br /&gt;
(non amd cpu motherboard can have it under other names(hints: Calgary,VT),but on AMD CPU Motherboards setting of that hardware device is&lt;br /&gt;
located under North Bridge section in Bios if you have it on your motherboard.&lt;br /&gt;
So i recommend to first check all pci devices with,spec. if you are unfamiliar with Bios or simply don&#039;t want to open it, if is not necessary ...&lt;br /&gt;
  lspci&lt;br /&gt;
and then try this procedure ,and after take a look on kernel messages as there is usually this message as reason and explanation for non-success:&lt;br /&gt;
 &amp;quot;... [fglrx] IOMMU is enabled, CrossFire are not supported on this platform&amp;quot;&lt;br /&gt;
(what means when IOMMU gonna be disabled Crossfire will be supported on this platform)&lt;br /&gt;
or you can find this kernel message,too:&lt;br /&gt;
 &amp;quot;... [fglrx] Disable IOMMU in BIOS options or kernel boot parameters to support CF&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Minimum do fast check with:(mostly only valid for amd cpu motherboards)&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: &lt;br /&gt;
(one of examples :&amp;quot;Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&amp;quot;)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! &lt;br /&gt;
note:not all usb keyboard those days can work with usb to ps2 adapters,but some can,and ps2 keyboards are really cheapest ones.&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  sudo amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some people reported that they need to reboot now,after this step to get success)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  sudo amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,&lt;br /&gt;
  sudo reboot&lt;br /&gt;
check increased performance in some benchmark (hint:basic version of popular windows benchmark for games --&amp;gt; Unigine Heaven is free for Ubuntu ) and enjoy&lt;br /&gt;
comparing and improving performance.. &lt;br /&gt;
 &lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..and in similar way you can add third card to chain..or CrossFire two dual gpu cards, what is called quad CrossFire...&lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with:&lt;br /&gt;
&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;

 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..&lt;br /&gt;
(non amd cpu motherboard can have it under other names(hints: Calgary,VT),but on AMD CPU Motherboards setting of that hardware device is&lt;br /&gt;
located under North Bridge section in Bios if you have it on your motherboard.&lt;br /&gt;
So i recommend to first check all pci devices with,spec. if you are unfamiliar with Bios or simply don&#039;t want to open it, if is not necessary ...&lt;br /&gt;
  lspci&lt;br /&gt;
and then try this procedure ,and after take a look on kernel messages as there is usually this message as reason and explanation for non-success:&lt;br /&gt;
 &amp;quot;... [fglrx] IOMMU is enabled, CrossFire are not supported on this platform&amp;quot;&lt;br /&gt;
(what means when IOMMU gonna be disabled Crossfire will be supported on this platform)&lt;br /&gt;
or you can find this kernel message,too:&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Disable IOMMU in BIOS options or kernel boot parameters to support CF&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Minimum do fast check with:(mostly only valid for amd cpu motherboards)&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: &lt;br /&gt;
(one of examples :&amp;quot;Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&amp;quot;)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! &lt;br /&gt;
note:not all usb keyboard those days can work with usb to ps2 adapters,but some can,and ps2 keyboards are really cheapest ones.&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  sudo amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some people reported that they need to reboot now,after this step to get success)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  sudo amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,&lt;br /&gt;
  sudo reboot&lt;br /&gt;
check increased performance in some benchmark (hint:basic version of popular windows benchmark for games --&amp;gt; Unigine Heaven is free for Ubuntu ) and enjoy&lt;br /&gt;
comparing and improving performance.. &lt;br /&gt;
 &lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..and in similar way you can add third card to chain..or CrossFire two dual gpu cards, what is called quad CrossFire...&lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with:&lt;br /&gt;
&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..&lt;br /&gt;
(non amd cpu motherboard can have it under other names(hints: Calgary,VT),but on AMD CPU Motherboards setting of that hardware device is&lt;br /&gt;
located under North Bridge section in Bios if you have it on your motherboard.&lt;br /&gt;
So i recommend to first check all pci devices with,spec. if you are unfamiliar with Bios or simply don&#039;t want to open it, if is not necessary ...&lt;br /&gt;
  lspci&lt;br /&gt;
and then try this procedure ,and after take a look on kernel messages as there is usually this message as reason and explanation for non-success:&lt;br /&gt;
 &amp;quot;... [fglrx] IOMMU is enabled, CrossFire are not supported on this platform&amp;quot;&lt;br /&gt;
(what means when IOMMU gonna be disabled Crossfire will be supported on this platform)&lt;br /&gt;
or you can find this kernel message,too:&lt;br /&gt;
&amp;quot;Disable IOMMU in BIOS options or kernel boot parameters to support CF&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Minimum do fast check with:(mostly only valid for amd cpu motherboards)&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: &lt;br /&gt;
(one of examples :&amp;quot;Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&amp;quot;)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! &lt;br /&gt;
note:not all usb keyboard those days can work with usb to ps2 adapters,but some can,and ps2 keyboards are really cheapest ones.&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  sudo amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some people reported that they need to reboot now,after this step to get success)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  sudo amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,&lt;br /&gt;
  sudo reboot&lt;br /&gt;
check increased performance in some benchmark (hint:basic version of popular windows benchmark for games --&amp;gt; Unigine Heaven is free for Ubuntu ) and enjoy&lt;br /&gt;
comparing and improving performance.. &lt;br /&gt;
 &lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..and in similar way you can add third card to chain..or CrossFire two dual gpu cards, what is called quad CrossFire...&lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with:&lt;br /&gt;
&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;

=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

== Get more fps in games ==&lt;br /&gt;
Change your cpu profile to performance:&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
This change is not permanent, to make it permanent write this line to /etc/rc.local before &amp;quot;exit 0&amp;quot; . If needet install the cpufreq package first.&lt;br /&gt;
&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..&lt;br /&gt;
(non amd cpu motherboard can have under other names(hints: Calgary,VT),but on AMD CPU Motherboards setting of that hardware device is&lt;br /&gt;
located under North Bridge section in Bios if you have in onboard.&lt;br /&gt;
So i recommend to first check all pci devices with,spec. if you are unfamiliar with Bios or simply don&#039;t want to open it, if is not necessary ...&lt;br /&gt;
  lspci&lt;br /&gt;
and then try this procedure ,and after take a look on kernel messages as there is usually this message as reason and explanation for non-success:&lt;br /&gt;
 &amp;quot;... [fglrx] IOMMU is enabled, CrossFire are not supported on this platform&amp;quot;&lt;br /&gt;
(what means when IOMMU gonna be disabled Crossfire will be supported on this platform)&lt;br /&gt;
or you can find this kernel message,too:&lt;br /&gt;
&amp;quot;Disable IOMMU in BIOS options or kernel boot parameters to support CF&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Minimum do fast check with:(mostly only valid for amd cpu motherboards)&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: &lt;br /&gt;
(one of examples :&amp;quot;Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&amp;quot;)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! &lt;br /&gt;
note:not all usb keyboard those days can work with usb to ps2 adapters,but some can,and ps2 keyboards are really cheapest ones.&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  sudo amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some people reported that they need to reboot now,after this step to get success)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  sudo amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,&lt;br /&gt;
  sudo reboot&lt;br /&gt;
check increased performance in some benchmark (hint:basic version of popular windows benchmark for games --&amp;gt; Unigine Heaven is free for Ubuntu ) and enjoy&lt;br /&gt;
comparing and improving performance.. &lt;br /&gt;
 &lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..and in similar way you can add third card to chain..or CrossFire two dual gpu cards, what is called quad CrossFire...&lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with:&lt;br /&gt;
&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;

=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

after that install playonlinux&lt;br /&gt;
&lt;br /&gt;
== Get more fps in games ==&lt;br /&gt;
Change your cpu profile to performance:&lt;br /&gt;
&lt;br /&gt;
cpufreq-set -g performance&lt;br /&gt;
&lt;br /&gt;
This change is not permanent, to make it permanent write this line to /etc/rc.local before &amp;quot;exit 0&amp;quot; . If needet install the cpufreq package first.&lt;br /&gt;
&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..&lt;br /&gt;
(non amd cpu motherboard can have under other names(hints: Calgary,VT),but on AMD cpu motherboard that is&lt;br /&gt;
located under North Bridge section in Bios.&lt;br /&gt;
so i recommend to first check all pci devices with &lt;br /&gt;
  lspci&lt;br /&gt;
and then try this procedure ,and after take a look on logs,and kernel messages as there is usually this message as reason and explanation for non-success:&lt;br /&gt;
 &amp;quot;... [fglrx] IOMMU is enabled, CrossFire are not supported on this platform&amp;quot;&lt;br /&gt;
&lt;br /&gt;
or at minimum do fast check with:(mostly only valid for amd cpu motherboards)&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! &lt;br /&gt;
note:not all usb keyboard those days can work with usb to ps2 adapters,but some can,and ps2 keyboards are really cheapest ones.&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  sudo amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some people reported that they need to reboot now,after this step to get success)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  sudo amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,&lt;br /&gt;
  sudo reboot&lt;br /&gt;
check increased performance in some benchmark (hint:basic version of popular windows benchmark for games --&amp;gt; Unigine Heaven is free for Ubuntu ) and enjoy&lt;br /&gt;
comparing and improving performance.. &lt;br /&gt;
 &lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..and in similar way you can add third card to chain..or CrossFire two dual gpu cards, what is called quad CrossFire...&lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with:&lt;br /&gt;
&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;

&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

after that install playonlinux&lt;br /&gt;
&lt;br /&gt;
== Get more fps in games ==&lt;br /&gt;
Change your cpu profile to performance:&lt;br /&gt;
&lt;br /&gt;
cpufreq-set -g performance&lt;br /&gt;
&lt;br /&gt;
This change is not permanent, to make it permanent write this line to /etc/rc.local before &amp;quot;exit 0&amp;quot; . If needet install the cpufreq package first.&lt;br /&gt;
&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..so i recommend to first check all pci devices with &lt;br /&gt;
  lspci &lt;br /&gt;
or at minimum do fast check with:&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! &lt;br /&gt;
note:not all usb keyboard those days can work with usb to ps2 adapters,but some can,and ps2 keyboards are really cheapest ones.&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  sudo amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some people reported that they need to reboot now,after this step to get success)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  sudo amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,&lt;br /&gt;
  sudo reboot&lt;br /&gt;
check increased performance in some benchmark (hint:basic version of popular windows benchmark for games --&amp;gt; Unigine Heaven is free for Ubuntu ) and enjoy&lt;br /&gt;
comparing and improving performance.. &lt;br /&gt;
 &lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..and in similar way you can add third card to chain..or CrossFire two dual gpu cards, what is called quad CrossFire...&lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with:&lt;br /&gt;
&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

== Get more fps in games ==&lt;br /&gt;
Change your cpu profile to performance:&lt;br /&gt;
&lt;br /&gt;
cpufreq-set -g performance&lt;br /&gt;
&lt;br /&gt;
This change is not permanent, to make it permanent write this line to /etc/rc.local before &amp;quot;exit 0&amp;quot; . If needet install the cpufreq package first.&lt;br /&gt;
&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..so i recommend to first check all pci devices with &lt;br /&gt;
  lspci &lt;br /&gt;
or at minimum do fast check with:&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! &lt;br /&gt;
note:not all usb keyboard those days can work with usb to ps2 adapters,but some can,and ps2 keyboards are really cheapest ones.&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  sudo amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  sudo amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,&lt;br /&gt;
  sudo reboot&lt;br /&gt;
check increased performance in some benchmark (hint:basic version of popular windows benchmark for games --&amp;gt; Unigine Heaven is free for Ubuntu ) and enjoy&lt;br /&gt;
comparing and improving performance.. &lt;br /&gt;
 &lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..and in similar way you can add third card to chain..or CrossFire two dual gpu cards, what is called quad CrossFire...&lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

after that install playonlinux&lt;br /&gt;
&lt;br /&gt;
== Get more fps in games ==&lt;br /&gt;
Change your cpu profile to performance:&lt;br /&gt;
&lt;br /&gt;
cpufreq-set -g performance&lt;br /&gt;
&lt;br /&gt;
This change is not permanent, to make it permanent write this line to /etc/rc.local before &amp;quot;exit 0&amp;quot; . If needet install the cpufreq package first.&lt;br /&gt;
&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..so i recommend to first check all pci devices with &lt;br /&gt;
  lspci &lt;br /&gt;
or at minimum do fast check with:&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! &lt;br /&gt;
note:not all usb keyboard those days can work with usb to ps2 adapters,but some can,and ps2 keyboards are really cheapest ones.&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (hint:basic version of popular windows benchmark for games --&amp;gt; Unigine Heaven is free for Ubuntu ) and enjoy&lt;br /&gt;
comparing and improving performance.. &lt;br /&gt;
 &lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..and in similar way you can add third card to chain..or CrossFire two dual gpu cards, what is called quad CrossFire...&lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

&lt;br /&gt;
after that install playonlinux&lt;br /&gt;
&lt;br /&gt;
== Get more fps in games ==&lt;br /&gt;
Change your cpu profile to performance:&lt;br /&gt;
&lt;br /&gt;
cpufreq-set -g performance&lt;br /&gt;
&lt;br /&gt;
This change is not permanent, to make it permanent write this line to /etc/rc.local before &amp;quot;exit 0&amp;quot; . If needet install the cpufreq package first.&lt;br /&gt;
&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..so i recommend to first check all pci devices with &lt;br /&gt;
  lspci &lt;br /&gt;
or at minimum do fast check with:&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! on mine 1st with IOMMU hardware built in, is just one ps2..ouch! )&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (hint:basic version of popular windows benchmark for games --&amp;gt; Unigine Heaven is free for Ubuntu ) and enjoy&lt;br /&gt;
comparing and improving performance.. &lt;br /&gt;
 &lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..and in similar way you can add third card to chain..or CrossFire two dual gpu cards, what is called quad CrossFire...&lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (Heaven for Ubuntu) and enjoy&lt;br /&gt;
&lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..and in similar way you can add third card to chain..or CrossFire two dual gpu cards, what is called quad CrossFire...&lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..so i recommend to first check all pci devices with &lt;br /&gt;
  lspci &lt;br /&gt;
or at minimum do fast check with:&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! on mine 1st with IOMMU hardware built in, is just one ps2..ouch! )&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (Heaven for Ubuntu) and enjoy&lt;br /&gt;
&lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..  &lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..so i recommend to first check all pci devices with &lt;br /&gt;
  lspci &lt;br /&gt;
or at minimum do fast check with:&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! mine haved just one ps2.. )&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (Heaven for Ubuntu) and enjoy&lt;br /&gt;
&lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..  &lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious for those who wants even more perfomance..&lt;br /&gt;

If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..so i recommend to first check all pci devices with &lt;br /&gt;
  lspci &lt;br /&gt;
or at minimum do fast check with:&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! mine haved just one ps2.. )&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (Heaven for Ubuntu) and enjoy&lt;br /&gt;
&lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..  &lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same CrossFired cards, vary, and is not same if running on&lt;br /&gt;
x16/x16 both,so called real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards with x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make significant difference,or in most cases diff.at all..and almost is not really important like this mentioned above about lanes,and most motherboards have dedicated pciex number to install second and even third card to work as intended,so please check your motherboard manual about that..&lt;br /&gt;
Some cards really scale 99-100% and have double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
hint:Usually some in mid range,in every generation, are best in scaling..up to 100%&lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
so workaround about that is obvious..&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;

&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;

== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..so i recommend to first check all pci devices with &lt;br /&gt;
  lspci &lt;br /&gt;
or at minimum do fast check with:&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! mine haved just one ps2.. )&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (Heaven for Ubuntu) and enjoy&lt;br /&gt;
&lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..  &lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see with:&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same Crossfired card vary and is not same if running on&lt;br /&gt;
x16/x16 both,real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make difference..and almost is not really important like this mentioned above..some cards really scale 100% and double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

&lt;br /&gt;
== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..so i recommend to first check all pci devices with &lt;br /&gt;
  lspci &lt;br /&gt;
or at minimum do fast check with:&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! mine haved just one ps2.. )&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (Heaven for Ubuntu) and enjoy&lt;br /&gt;
&lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..  &lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but two gpu on one card user, like in case of 6990&lt;br /&gt;
will be see mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same Crossfired card vary and is not same if running on&lt;br /&gt;
x16/x16 both,real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make difference..and almost is not really important like this mentioned above..some cards really scale 100% and double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

== How to enable CrossFire manually in terminal ==&lt;br /&gt;
note : up to now ,as i know IOMMU need to be switched off ,best if IOMMU was &amp;quot;off&amp;quot;in bios when you was doing last installation of Ubuntu.. (some motherboards have that device,most older do not have it) so check your case with &amp;quot;lspci&amp;quot; and take a look in your Bios..so i recommend to first check all pci devices with &lt;br /&gt;
  lspci &lt;br /&gt;
or at minimum do fast check with:&lt;br /&gt;
  lspci | grep IOMMU&lt;br /&gt;
then if you do not find noting similar to:&lt;br /&gt;
IOMMU: Advanced Micro Devices, Inc. [AMD/ATI] RD990 I/O Memory Management Unit (IOMMU)&lt;br /&gt;
as if you find it,you will need to disable it,in Bios..and that is usually not enough in some cases,and can lead to need to recompile your kernel ,as with simple disabling you can lost support to usb mouse and usb keyboard(easy simple &amp;quot;dirty&amp;quot; workaround is to use ps2 keyboard,and if your motherboard have two ps2 ports ,you can use ps2 connection to usb keyboard and ps2 connection to usb mouse,otherwise, you was  warned in advance! mine haved just one ps2.. )&lt;br /&gt;
&lt;br /&gt;
so now, after you know AMD proven facts which can prevent CrossFire to be Enabled,and you are sure that you don&#039;t have IOMMU as hardware device ,or is already disabled,you are safe to proceed further:&lt;br /&gt;
&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (Heaven for Ubuntu) and enjoy&lt;br /&gt;
&lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..  &lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system,&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but to somebody like two gpu cards user like in case of 6990&lt;br /&gt;
will be mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that performance of same Crossfired card vary and is not same if running on&lt;br /&gt;
x16/x16 both,real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make difference..and almost is not really important like this mentioned above..some cards really scale 100% and double performance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

|- &lt;br /&gt;
| &amp;lt;br /&amp;gt;*PLEASE READ FIRST!&lt;br /&gt;
&#039;&#039;&#039;Which Radeon cards are no longer supported by ATI&#039;s Catalyst?&#039;&#039;&#039;&lt;br /&gt;
&amp;lt;br /&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500, Mobility RadeonHD 2300&#039;&#039;&#039;&lt;br /&gt;
If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;
 chmod a+x {{Catalystrunname}}&lt;br /&gt;
 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;
&lt;br /&gt;
== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;BETA/EXPERIMENTAL&#039;&#039; ==&lt;br /&gt;
Note that the beta drivers aren&#039;t neccassarily newer than the stable drivers.&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst-14.6beta1.0jul11 &amp;amp;&amp;amp; cd catalyst-14.6beta1.0jul11&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/beta/linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
 unzip linux-amd-catalyst-14.6-beta-v1.0-jul11.zip&lt;br /&gt;
 cd fglrx-14.20&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
&lt;br /&gt;
 sudo ./amd-driver-installer-14.20-x86.x86_64.run --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails, there is also an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation]&lt;br /&gt;
&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;
&lt;br /&gt;
== Before you start ==&lt;br /&gt;
If you have previously attempted installing Catalyst, remove any leftover files by following the [[#Removing_Catalyst.2Ffglrx| Removing the Driver]] section. Make sure &#039;&#039;universe&#039;&#039; and &#039;&#039;multiverse&#039;&#039; are enabled in your repository sources (System -&amp;gt; Administration -&amp;gt; Software Sources).&lt;br /&gt;
or Applications-&amp;gt;Ubuntu Software Center-&amp;gt;Edit-&amp;gt;Software sources-&amp;gt;Other software: check canonical partners.&lt;br /&gt;
&lt;br /&gt;
Install the prerequisite packages:&lt;br /&gt;
 sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If you are using the x86_64 architecture (64 bit)&#039;&#039;:&lt;br /&gt;
 sudo apt-get install lib32gcc1&lt;br /&gt;

== Installing Catalyst Manually (from AMD/ATI&#039;s site) &#039;&#039;STABLE&#039;&#039; ==&lt;br /&gt;
&lt;br /&gt;
=== Download the latest Catalyst package ===&lt;br /&gt;
This package contains both the 32-bit and 64-bit driver.&lt;br /&gt;
&lt;br /&gt;
 mkdir catalyst{{Catalystversion}} &amp;amp;&amp;amp; cd catalyst{{Catalystversion}}&lt;br /&gt;
 wget &amp;lt;nowiki&amp;gt;--referer=&#039;http://support.amd.com/en-us/download/desktop?os=Linux+x86&#039; http://www2.ati.com/drivers/linux/&amp;lt;/nowiki&amp;gt;{{Catalystfilename}}&lt;br /&gt;
 unzip {{Catalystfilename}}&lt;br /&gt;
&lt;br /&gt;
=== Create and install .deb packages ===&lt;br /&gt;
If you have Wine installed, the driver installation may fail due to a conflict with a library included with Wine. In this case you&#039;ll need to [[#fglrx-core_conflicts_with_libopencl1| modify the fglrx-core package]] before executing the second command below.&lt;br /&gt;
&lt;br /&gt;

 sudo ./{{Catalystrunname}} --buildpkg Ubuntu/utopic&lt;br /&gt;
 sudo dpkg -i fglrx*.deb&lt;br /&gt;
&lt;br /&gt;
If building .deb packages fails you can try an [http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Alternative_Manual_Installation Alternative Manual Installation] which does NOT create deb packages and might cause some trouble when trying to uninstall.&lt;br /&gt;

&lt;br /&gt;
== In case of failure ==&lt;br /&gt;
Remember these steps before you reboot your computer.&lt;br /&gt;
&lt;br /&gt;
If the X server fails to start, switch to a new TTY using ctrl+alt+F2. Log in, and attempt to start the X server.&lt;br /&gt;
&lt;br /&gt;
 sudo startx&lt;br /&gt;
&lt;br /&gt;
If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

== how to enable CrossFire manually in terminal ==&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (Heaven for Ubuntu) and enjoy&lt;br /&gt;
&lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..  &lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but to somebody like two gpu cards user like in case of 6990&lt;br /&gt;
will be mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that permomance of same Crossfired card vary and is not same if running on&lt;br /&gt;
x16/x16 both,real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make difference..and almost is not really important like this mentioned above..some cards really scale 100% and double perfomance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;

If your card is on that list, you are limited to open-source drivers on Ubuntu Lucid/10.04 (and later).&lt;br /&gt;
NOTE: If you enter your card information on AMD/ATI&#039;s driver page, it will offer you the Catalyst 9-3 driver to download. However, the Catalyst 9-3 driver doesn&#039;t support X servers past 1.5, and it will not work with any modern/supported version of Ubuntu! !!!SO BE CAREFUL!!! If you tried to install Catalyst on a system with one of these cards, see the &#039;Removing the Driver&#039; section to restore the default/pre-installed drivers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;ATI RadeonHD 2x00 - 4xx0 cards&#039;&#039;&#039;&lt;br /&gt;
If you have one of these cards, you have the option of using the Catalyst Legacy driver, but you will need to install/use Ubuntu 12.04.1&lt;br /&gt;
&lt;br /&gt;
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl &#039;&#039;&#039;+ Shift&#039;&#039;&#039; + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).&lt;br /&gt;

If it fails to start, you will likely see a stacktrace, and immediately above it will be something along the lines of &amp;quot;Could not stat /usr/lib64/fglrx/switchlibGL&amp;quot; which means that you failed to copy the executables properly. Ctrl+c, and immediately copy the switchlibGL and switchlibglx executables to the fglrx folder in /usr/lib64/ or /usr/lib32/. &lt;br /&gt;
&lt;br /&gt;
If all else fails, revert your xorg.conf and reboot.&lt;br /&gt;
&lt;br /&gt;
 sudo cp /etc/X11/xorg.conf.orig /etc/X11/xorg.conf&lt;br /&gt;
&lt;br /&gt;
This should return your original display.&lt;br /&gt;
&lt;br /&gt;
== Generate a new /etc/X11/xorg.conf file (DO IT AFTER INSTALLATION OF .DEB Packages) ==&lt;br /&gt;
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file.  It is entirely dependent on your configuration.  The following subsections will attempt to address possible (and tested) variations for their respective configurations.&lt;br /&gt;
&lt;br /&gt;
=== Generic Config ===&lt;br /&gt;
This will work for most people:&lt;br /&gt;
 sudo amdconfig --initial -f&lt;br /&gt;
&lt;br /&gt;
=== Minimal Config ===&lt;br /&gt;
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that&#039;s not fully supported by amdconfig. Here follows the entirety of a minimal xorg.conf file for the Radeon HD 6870:&lt;br /&gt;
&lt;br /&gt;
 Section &amp;quot;Device&amp;quot;&lt;br /&gt;
  Identifier &amp;quot;ATI radeon 6870&amp;quot;&lt;br /&gt;
  Driver &amp;quot;fglrx&amp;quot;&lt;br /&gt;
 EndSection&lt;br /&gt;
&lt;br /&gt;
== Force use of the new xorg.conf &#039;&#039;(if necessary)&#039;&#039;==&lt;br /&gt;
Some people find that changes to xorg.conf don&#039;t get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:&lt;br /&gt;
&lt;br /&gt;
 sudo amdconfig &amp;lt;nowiki&amp;gt;--input=/etc/X11/xorg.conf --tls=1&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Test your installation ==&lt;br /&gt;
NOTE: if you don&#039;t reboot first, fglrxinfo gives an error message.&lt;br /&gt;
Reboot the computer and type&lt;br /&gt;
 fglrxinfo&lt;br /&gt;
into the terminal. If the vendor string contains AMD, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
display: :0.0  screen: 0&lt;br /&gt;
OpenGL vendor string: Advanced Micro Devices, Inc.&lt;br /&gt;
OpenGL renderer string: AMD Radeon HD 6670  --  (This line may be different depending on what graphics card you are using!)&lt;br /&gt;
OpenGL version string: 4.3.12798 Compatibility Profile Context 13.35.1005  --  (This line may be different depending on what graphics card and Catalyst version you are using!)&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
Now, try:&lt;br /&gt;
 fgl_glxgears&lt;br /&gt;
If you experience issues or a hang, you may need to disable fast TLS.&lt;br /&gt;
 sudo amdconfig --tls=0&lt;br /&gt;
&lt;br /&gt;
=== Just in case ===&lt;br /&gt;
Write down or remember this series of Alt+PrntScr key combinations, just in case your screen should go black and Ctrl+Alt+F1 and Ctrl+Alt+Backspace doesn&#039;t work.&lt;br /&gt;
&lt;br /&gt;
Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b&lt;br /&gt;
&lt;br /&gt;
These key-presses will reboot the system safely. To remember the key-presses, remember this nonsensical phrase: &amp;quot;Raising Skinny Elephants Is Never Utterly Boring&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
An alternative would be to hold down Ctrl+Alt+SysRq (SysRq is usually the same key as PrintScreen) and type very slowly R E I S U B. A way to remember this is by inverting the word: &amp;quot;BUSIER&amp;quot; or remembering a phrase: &amp;quot;Restart Even If System Utterly Broken&amp;quot;. This would also safely shutdown the system.&lt;br /&gt;

&lt;br /&gt;
after that install playonlinux&lt;br /&gt;
&lt;br /&gt;
== Get more fps in games ==&lt;br /&gt;
Change your cpu profile to performance:&lt;br /&gt;
&lt;br /&gt;
cpufreq-set -g performance&lt;br /&gt;
&lt;br /&gt;
This change is not permanent, to make it permanent write this line to /etc/rc.local before &amp;quot;exit 0&amp;quot; . If needet install the cpufreq package first.&lt;br /&gt;
&lt;br /&gt;
== how to enable Crossfire manually in terminal ==&lt;br /&gt;
Check if both cards system see,&lt;br /&gt;
  amdconfig --lsa&lt;br /&gt;
if that is adapter 0 and 1 then ,just proceed,to add crossfire chain,this way&lt;br /&gt;
  amdconfig --cfa --adapter=0,1&lt;br /&gt;
(i read that some reported that they need to reboot now,some get same result with only one final reboot..)&lt;br /&gt;
then activate crossfire&lt;br /&gt;
  amdconfig --cf on --adapter=0,1&lt;br /&gt;
reboot,check increased performance in some benchmark (Heaven for Ubuntu) and enjoy&lt;br /&gt;
&lt;br /&gt;
this is valid for two separated single gpu card,but is similar on two gpu on one card,where crossfire is automatically enabled..  &lt;br /&gt;
&lt;br /&gt;
this is valid ,when you install driver for just one adapter,same like in manual above&lt;br /&gt;
&lt;br /&gt;
just to be sure ,you can anytime check crossfire status with&lt;br /&gt;
CrossFire Diagnostics:&lt;br /&gt;
  amdconfig --lscs&lt;br /&gt;
note message if crossfire is enabled or disabled on current device!&lt;br /&gt;
note mesage about how CrossFire can work on your particular system&lt;br /&gt;
most will get just: &lt;br /&gt;
CrossFire can work with P2P mapping through GART&lt;br /&gt;
but to somebody like two gpu cards user like in case of 6990&lt;br /&gt;
will be mentioned side port connection..&lt;br /&gt;
&lt;br /&gt;
and what you can officially pair with,you will see&lt;br /&gt;
  amdconfig --lscc&lt;br /&gt;
note : that permomance of same Crossfired card vary and is not same if running on&lt;br /&gt;
x16/x16 both,real one CrossFire motherboards(one of famous is Sabertooth ,and above) ,or on x16/x8  or on cheap CrossFire motherboards x16/x4 lanes..&lt;br /&gt;
pciex2.0 or pciex3.0 still not make difference..and almost is not really important like this mentioned above..some cards really scale 100% and double perfomance,but most are more close or more far away from that..so bench it! &lt;br /&gt;
note: two cards with diff gpu clock will work together on clock of less clocked card..&lt;br /&gt;
