= Open Source Drivers =
By default, Ubuntu will already try to use one of the open source drivers for your hardware. If the feature set and stability work for you, then you don't need to change anything.

The drivers that may be used are
* '''vesa''' Lowest common denominator across all graphics vendor, not many features.
* '''ati''' Actually a facade that will invoke the radeon driver.
* '''radeon''' Driver support all radeon classes of hardware - with limited 3D for newer cards.
* '''radeonhd''' An alternate driver support R520 hardware and later.

By default there is no configuration file for X anymore, so X will try to do the right thing.

If you run into stability problems with 3D applications using the radeon/radeonhd drivers, consider trying a more recent kernel.
[http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.3/ mainline-2.6.29.3] did the trick on a few machines.

There's an ongoing debate about how and if the radeon and radeonhd drivers will be used in the future. For more information, see http://wiki.x.org/wiki/RadeonFeature

= Installing Open Source Edge Drivers =

These drivers are built regularly from the X.Org git repository. So sometimes they work, sometimes they don't. However, they have been stable for me, and are the only drivers that work for me. The fglrx drivers hang my system, and the standard "radeon" driver does not support a 2560x1600 resolution.

To install:

First add the repository https://launchpad.net/~tormodvolden/+archive/ppa. Instructions on how to do that are on that page. Then update your packages using Update Manager, and then add the ''xserver-xorg-video-radeonhd'' package. When you log in, you may be using the new driver, but you will probably still be using the radeon driver. To switch to the radeonhd driver, add this to '''/etc/X11/xorg.conf''' :

<pre>Section "Device"
Driver "radeonhd"
EndSection</pre>

= The Ubuntu way to install the Proprietary Drivers =

== Restricted Drivers Manager ==
* Ubuntu 9.04 (Jaunty) provides a notification saying that there are restricted drivers available
* Go to the Restricted Drivers Manager and enable the "ATI accelerated graphics driver"
* Ubuntu will then install and configure the driver for you

Note that you will be restricted to the drivers for you version of Ubuntu that Canonical deem as stable. This may not give you the latest drivers, but should be safest. The driver installed this way does not work with Radeon X1300.

= Installing the drivers manually =
*PLEASE READ FIRST!
This portion of the guide works, since I have used it myself. I guess the rest of the guide is broken or it may be because the new driver doesn't support any of the older ATI cards anymore.

'''Which cards does ATI no longer support?'''
The ATI Radeon 9500-9800, X300-X2100, Xpress. See the complete list [http://wiki.cchtml.com/index.php/9.4 here.]
If your card is on that list, you are restricted to the 9.3 driver - however since 9.3 driver doesn't support xorg-xserver 1.6, it will not work with Jaunty! This guide currently is for installing 9.7. !!!SO BE CAREFUL!!!

_______________________________________________

I recommend using copy and paste. However, you can Ctrl + C in your browser but you cannot Ctrl + V in the terminal. When you have copied something simply use Ctrl + Shift + V or Shift + Insert to paste into the terminal or go to the terminals menu, select edit and click paste. This method will ensure there are no typing mistakes and will greatly speed up the install process.

''If you are using the x86_64 architecture (64 bit), be sure to install "ia32-libs" before proceeding!''

Make sure ''universe'' and ''multiverse'' are enabled in your repository sources.

===''Before you start''===
Install the necessary programs
{{Box Terminal|
sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++5 dkms
}}

===''1. Download the latest Catalyst package.''===

Download page: Catalyst {{catalystversion}} -- File: {{catalystfilename}}. This package contains both the 32-bit and 64-bit driver.

Open a terminal window and switch to the directory you downloaded the installer to. (Example: $ cd Desktop)

Make sure your directory path does not contain spaces

===''2. Create .deb packages.''===
{{Box Terminal|
sh {{Template:Catalystfilename}} --buildpkg Ubuntu/jaunty
}}

===''3. Just in case''===
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't work.

Alt+PrntScr+r, Alt+PrntScr+s, Alt+PrntScr+e, Alt+PrntScr+i, Alt+PrntScr+n, Alt+PrntScr+u, Alt+PrntScr+b

These keypresses will reboot the system safely. To remember the keypresses, remember this nonsensical phrase: "Raising Skinny Elephants Is Never Utterly Boring"

===''4. Install .debs.''===

Install the debs, depending on if you're on a 32-bit or 64-bit system:

* For 32-bit systems

{{Box Terminal|
sudo dpkg -i xorg-driver-fglrx_*.deb fglrx-kernel-source_*.deb fglrx-amdcccle_*.deb
}}

(This may fail due to a missing dkms. If so install this first. Also check the version numbers (8.632) against the created debs)

* For 64-bit systems

{{Box Terminal|
sudo dpkg -i xorg-driver-fglrx_*.deb fglrx-kernel-source_*.deb fglrx-amdcccle_*.deb
}}
''Using [http://en.wikipedia.org/wiki/Command_line_completion tab completion] can make this command easier.''

=== ''5. Additional 64-bit instructions'' ===

--If you have installed the "ia32-libs" package most likely you will not need to do this step.--

If you have a 64 bit install, the above dpkg command may complain that "Errors were encountered while processing: fglrx-amdcccle". This is because of a dependency of the amdccle package on 32 bit libraries. If you receive this error, issue the following command after the above dpkg command, which will force the installation of all of the 32 bit dependencies, and then the amdcccle package:

{{Box Terminal|
sudo apt-get -f install
}}

Catalyst {{Template:Catalystversion}} on 64-bit systems requires the ''--force-overwrite'' command in the above ''dpkg'' command:
{{Box Terminal|
sudo dpkg -i --force-overwrite xorg-driver-fglrx_*.deb fglrx-kernel-source_*.deb fglrx-amdcccle_*.deb fglrx-modaliases_*.deb libamdxvba1_*.deb
}}
''Using [http://en.wikipedia.org/wiki/Command_line_completion tab completion] can make this command easier.''

== Finishing the Install: Configuration ==

===''Now you'll have to edit your xorg.conf''===

'''Note: If you've used fglrx previously, skip down to step 6.'''

For Ubuntu:
{{Box Terminal|
sudo gedit /etc/X11/xorg.conf
}}

For Kubuntu:
{{Box Terminal|
sudo kate /etc/X11/xorg.conf
}}

and add the following line to the Device section (if it does not already exist). Include the following lines without '''[...]''':
<pre>Section "Device"
[...]
Identifier "SOME IDENTIFIER"
[...]
Driver "fglrx"
[...]
EndSection</pre>
Save and exit, then run

===''6. Generate a new /etc/Xorg.conf file''===

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.

==== Generic Config ====
This will work for most people:
{{Box Terminal|
sudo aticonfig --initial -f
}}

==== X2 Cards ====
If you have an X2 card (e.g. 4870X2), use... !!Do not use for two separate cards in crossfire!!
{{Box Terminal|
sudo aticonfig --initial -f --adapter<nowiki>=</nowiki>all
}}

==== Dual/Multi Monitors ====
If you have a dual monitor display (also known as "Big Desktop"), use:
{{Box Terminal|
sudo aticonfig --initial -f --set-pcs-str<nowiki>=</nowiki>"DDX,EnableRandR12,FALSE"
}}
This was confirmed in http://phoronix.com/forums/showthread.php?t=18553.

===''7. Force use of /etc/Xorg.conf file''===
Some people find that changes to xorg.conf don't get used by the driver. To force the ati driver to adopt changes made to xorg.conf, type the following command:

{{Box Terminal|
sudo aticonfig <nowiki>--input=/etc/X11/xorg.conf --tls=1</nowiki>
}}

===''8. Test your installation''===
Finally, reboot the computer and type
{{Box Terminal|
fglrxinfo
}}
into the terminal. If the vendor string contains ATI, you have installed the driver successfully. Release 9.6 looks like:
<pre>
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon HD 4800 Series (This line may be different depending on what graphics card you are using.)
OpenGL version string: 2.1.8673
</pre>

Please note: Depending on the particular ATI card that you own, you may or may not automatically have all of the relevant driver features enabled. R500 and R600 cards (X1xxx, HD series, and newer) in particular will need TexturedVideo enabled in Xorg.conf (rather than the traditional VideoOverlay) in order to support Xv accelerated video playback.

=HOW TO UPDATE DRIVER=

To update your driver to a new version (say 9.5 to 9.6) first disable the current driver through Ubuntu's Hardware Manager or use EnvyNG to remove the driver, then go to synaptic and search for "xorg-driver-fglrx" without the quotes and mark it for "Complete removal" and hit "Apply" then reboot your computer. Now simply repeat steps #1, 2, 4 and finally run these commends in a terminal: {{Box Terminal|
sudo aticonfig --initial -f
}}
in a terminal. If it doesn't give an error you should be good.

If you have an X2 card (e.g. 4870X2), use... !!Do not use for two separate cards in crossfire!!
{{Box Terminal|
sudo aticonfig --initial -f --adapter<nowiki>=</nowiki>all
}}
instead in a terminal to generate the /etc/Xorg.conf file.

and

{{Box Terminal|
sudo aticonfig <nowiki>--input=/etc/X11/xorg.conf --tls=1</nowiki>
}}

then reboot.

It is very important that you COMPLETELY remove the old driver which includes the config files because when upgrading without uninstalling the old driver I noticed even though the new driver installed and worked there were some annoying problems that I experienced but after I completely uninstalled the old driver then installed the new one, it worked perfectly.

=HOW TO REMOVE DRIVER=

To completely remove the driver disable the current driver through Ubuntu's Hardware Manager or use EnvyNG to remove the driver, then go to synaptic and search for "xorg-driver-fglrx" without the quotes and mark it for "Complete removal" and hit "Apply" then reboot your computer.

Alternatively, use the following command from the terminal.

{{Box Terminal|
sudo apt-get remove --purge xorg-driver-fglrx
}}

=Tweaks=
# Add tweaks as needed: http://ubuntuforums.org/showthread.php?t=849422
# Restart X, if it doesn't work, you can use the "vesa", "ati", "radeon" or "radeonhd" driver in the mean time, until you make it work.
# If you downgraded X to make fglrx work: enter synaptic, make sure all packages with "xorg" and "x11" are locked so that you can update and upgrade without worries.

Done! Now run amdcccle, glxgears, nexuiz, warsow etc :)

= Issues =

== Installation ==
There are some system configurations on which '''none''' of the installation alternatives work with the latest 9.5 driver (please add; also please add if you got it to work in one of the listed setups):
* Ubuntu 9.04 (x64 and i386) on x86_64 with Radeon HD4870X2 and 9.5 driver: Framebuffer error ("No valid linear framebuffer address"), garbled screen.
** Working 9.04 (x64) on x86_64 with Radeon4870X2 and 9.4 driver: use 'aticonfig --initial -f --adapter=all'
** Working 9.04 (x64) on x86_64 with Radeon4870X2 and 9.6 driver: use 'aticonfig --initial -f' (without adapter=all, if you only have one screen)
* Ubuntu 9.04 (x64) on x86_64 with Radeon HD3870X2 and 9.5 driver: "No supported adapters detected."
* Ubuntu 9.04 (x64) on x86 and x86_64 with Radeon HD4850X2: Framebuffer error, garbled screen.
* Ubuntu 9.04 (x64) on x86_64 with Radeon HD4850: Framebuffer error, garbled screen (with automatic log-on, using the restricted drivers manager installation).
* Ubuntu 9.04 (x64) on x86_64 with Radeon HD 3300 (790GX): garbled screen.
**Working Radeon HD 3300 connected to an HDTV, I had a garbled screen before, I reinstalled Ubuntu, then follow manual steps closely. Reinstalled because I didn't know how to remove fglrx, but you may be able to avoid reinstalling by following fglrx complete removal in this guide.
**Working 790GX (A790GMH/128M) with 9.5 driver after manual install (following install with envyng, which might be older version as of 25/5/09). Able to change display resolution which before was not working.
**Working 790GX (MSI 790GX-G65): Now able to call System/Video Configuration which hang up. This driver also reduced the power consumption by 15 W (from 93 W down to 78 W). Thank you for that great installation guide.
** Working Radeon HD 3450 connected to an HDTV on Kubuntu 9.04. Followed manual install of latest drivers (9.6) to the letter, rebooted, and works fully.

== Mesa drivers ==
If fglrxinfo reports that Indirect rendering by Mesa is in place, even though you have installed ATI driver, you might want to remove Mesa:

*Remove the package xserver-xgl.
:<pre>sudo apt-get remove xserver-xgl</pre>
:'''Explanation:''' If you installed this previously in order to make compiz work, it will not allow direct rendering on your display. You can check out if this is what it causing the problem by running
:<pre>DISPLAY=:0 glxinfo | grep render</pre>
:If it returns an ATI renderer, it means that xgl is being displayed indirectly on the display 1. (Taken from [http://ubuntuforums.org/showthread.php?t=740287])

:'''Warning:''' This might make your compiz stop working as it is configured to use XGL. A solution might be to run the Envy script in order to configure compiz. Or, if Compiz stopped working due to "Composite" problem, check that the following is set in the /etc/X11/xorg.conf
<pre>
Section "Extensions"
Option "Composite" "Enable"
EndSection
</pre>

----

*Check for AGP and DRI errors in /var/log/Xorg.0.log like these are:
:(EE) fglrx(0): [agp] unable to acquire AGP, error -1023
:(EE) fglrx(0): cannot init AGP
:(EE) fglrx(0): atiddxDriScreenInit failed, GPS not been initialized.
:(WW) fglrx(0): * DRI initialization failed! *

:If you have Intel 8285P and E7205 chipsets and AGP not detected then you have to remove the i82875p_edac module and restart a some others:
<pre>rmmod i82875p_edac
rmmod fglrx
rmmod intel-agp
rmmod agpgart
modprobe agpgart
modprobe intel-agp
modprobe fglrx</pre>

:Blacklist the modules e7xxx_edac so it doesn't start up again when booting - add the following line at the beginning of /etc/modprobe.d/blacklist:
:<pre>blacklist i82875p_edac</pre>

:This has been known to fix issues with -Mesa -AGP -DRI -Google earth and -suspend to RAM (s2ram).

:'''Explanation:''' http://openwetware.org/wiki/Computing/Linux/Ubuntu

----

*Check you are running the correct kernel.
:'''Explanation:''' If you're upgrading from Gutsy to Hardy in some instances the Grub bootloader does not get updated and the new kernel is not loaded.
:Run in a terminal:
:<pre>uname -r</pre>
:If the output starts with 2.6.22 or below you are not using the current kernel and the Ati drivers will not load properly.

If this doesn't help, try [[Ubuntu Gutsy Installation Guide#Verifying]], or other links: [http://wiki.cchtml.com/index.php/Troubleshooting#No_3D_acceleration], [http://www.thinkwiki.org/wiki/Problems_with_fglrx#Perpetual_Mesa_GLX_Indirect_on_Debian], [http://ubuntuforums.org/archive/index.php/t-475699.html].

== Hang at logout ==

If you experience hangs when logging out (of X) it is probably due to the /etc/ati/authatieventsd.sh script looking for X authorisation files in the wrong place when it starts up. You can kill the hanging authatieventsd.sh processes from a console tty to allow the shutdown of the X server. This can be fixed permanently with:

<pre>sudo mkdir -p /var/lib/xdm/authdir
sudo ln -s /var/run/xauth /var/lib/xdm/authdir/authfiles</pre>

If that doesn't work then you can disable atieventsd with this command:

<pre>sudo /usr/sbin/update-rc.d -f atieventsd remove</pre>

Before the above commands verify that /etc/ati/authatieventsd.sh exists after build and install, if not just do :
(assuming that the installer is in your home directory)

<pre>sh ati-driver-installer-8-12-x86.x86_64.run --extract driver</pre>

<pre>sudo cp ~/driver/packages/Ubuntu/dists/jaunty/replacements/authatieventsd.sh /etc/ati/authatieventsd.sh</pre>

(jaunty is to be replaced by the name used at the building stage (intrepid,hardy,8.10,8.04,etc...)

<pre>sudo chmod +x /etc/ati/authatieventsd.sh</pre>

just reboot login and ctrl+alt+backspace to try

== Suspend/Hibernation ==

Suspend hibernation '''works''' with the latest driver.

For ATI X1400, to get the laptop to wake up from suspend, I had to change the following in /etc/default/acpi-support:

<pre>
SAVE_VBE_STATE=false

POST_VIDEO=false

ENABLE_LAPTOP_MODE=false
</pre>

<blockquote>
Comment: This is a little surprising, since the comments at the beginning of /etc/default/acpi-support seem to make it quite clear that those settings are ignored unless you add "acpi-support" to SUSPEND_METHODS. --[[User:Bewst|Bewst]] 23:22, 19 December 2008 (UTC)
</blockquote>

For Radeon 3200, to wake up from suspend, I had to add the following lines to /etc/X11/xorg.conf:
(This settings is not good option, if you are using compiz-fusion or any other transparency-based thingie. Not working for HD 3850)

<pre>
Section "Extensions"
Option "Composite" "Disable"
EndSection

Section "ServerFlags"
Option "AIGLX" "off"
EndSection
</pre>

Another way to get it working is to do enable Composite, but when you want to suspend simply disable Compiz Fusion. How would you do that? Easy! Install the fusion-icon package (in repos by default):

<code>
sudo apt-get install fusion-icon
</code>

After you have done that, launch it (Applications > System > Compiz Fusion Icon) and it appears in your notification area. To switch, simply right-mouse click on the icon and select Metacity. Your desktop will flicker and windows will dissapear, but after a while they appear again. Now try to suspend.

When you wake up again, you can (hopefully) unlock your screen and there you go! Now you want Compiz back again, so right-mouse-click on the Compiz Fusion Icon and select Compiz again. Desktop flickering again, but then voila! Your Compiz Fusion Desktop is back again! (At least, that is how it is supposed to work)

KNOWN PROBLEM: When you switch back, all your windows are on the same desktop. This happens because you switched to metacity.

Hopefully this helped some people, as it did for me!
Solution posted by zwyber@gmail.com

== Can't remove fglrx with dpkg ==

If dpkg really-really refuses to remove an older fglrx-package, it might be needed to edit /var/lib/dpkg/diversions and remove a few lines. This is a hack and should be avoided.

== This module/version combo is already installed ==

If you get this error-message, simply uninstall the previous version before installing the new one with:
{{Box Terminal|
sudo dkms remove -m fglrx -v 8.522 --all
}}

== New kernel installed? ==
I found out that when getting a new kernel the fglrx kernel-module is not installed for your new kernel.
You can do that by these simple steps:
{{Box Terminal|
sudo dkms build -m fglrx -v 8.552 -k `uname -r` 
sudo dkms install -m fglrx -v 8.552 -k `uname -r`
}}

if amdcccle doesn't work and says Identifier is not a valid word. Use lower case letter in xorg.conf

Ubuntu Gutsy Installation Guide

2009-09-14T23:10:21Z

91.214.46.18: /* Installation */

dors-andrey-viagra1.txt;3;10

== Post-Installation Checks and Tweaks ==
===Verifying===
Run the following command to check its output to ensure the fglrx driver is installed properly:

<pre>
$fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI MOBILITY RADEON X300
OpenGL version string: 2.1.7415 Release
</pre>

64bit Users only ( 32bit users can continue to the fglrxinfo test ), after rebooting you may have noticed that you cant open aticonfig, and the fglrxinfo test below may not show ati in the info from the test, to fix this in terminal do the following command
<pre>
sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so.1
</pre>

The <code>OpenGL vendor string</code> should read '''ATI''' and not '''Mesa'''.

'''If it still says ''Mesa'' and not ''ATI'', even after re-enabling the driver from the Restricted-manager:'''
You can try the following:
:*<pre>$ less /var/log/Xorg.0.log |grep EE</pre> if this command returns <code>(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work</code> then remove the kernel module and reinstall it.
:: <pre>$ sudo dkms remove -m fglrx -v 8.471 --all</pre>

:*Remove all the packages provided by the <code>xserver-xorg-video-all</code> meta-package (search for it using Synaptic or Adept), then restart the machine. The X Server should now use the new fglrx driver by force (provided the driver is being used in ''xorg.conf'').
::If you can't log in after this, you'll have to log in to a terminal in the login screen, and reinstall the <code>xserver-xorg-video-all</code> package. Your problem is probably somewhere else. (taken from [http://ubuntuforums.org/showpost.php?p=3655658&postcount=139]).

:*Remove the package xserver-xgl.
::'''Explanation:''' If you installed this previously in order to make compiz work, it will not allow direct rendering on your display. You can check out if this is what it causing the problem by running
::<pre>DISPLAY=:0 glxinfo | grep render</pre>
::If it returns an ATI renderer, it means that xgl is being displayed indirectly on the display 1. (Taken from [http://ubuntuforums.org/showthread.php?t=740287])
::'''Warning:''' This might make your compiz stop working as it is configured to use XGl. A solution might be to run the Envy script in order to configure compiz.

Note: Here is the [[glxinfo]] of a good install (for those interested).

=== Enable laptop mode on battery power ===

Enabling laptop mode on battery power gives you much better battery life, however be aware that sometimes it causes odd hangs.

Switch ENABLE_LAPTOP_MODE to true
{{Box File|/etc/default/acpi-support|
<pre>
# Switch to laptop-mode on battery power - off by default as it causes odd
# hangs on some machines
ENABLE_LAPTOP_MODE=true
</pre>
}}

Switch FGLRX_ACPI_SWITCH_POWERSTATES to true
{{Box File|/etc/default/fglrx|
<pre>
# Uncomment the next line to enable powerstate switching on ACPI
# events for lid open/close and AC adapter on/off
FGLRX_ACPI_SWITCH_POWERSTATES=true
</pre>
}}

=== Additional configure with aticonfig tool ===
You can configure the driver even further with the '''aticonfig''' tool, more information can be found at [[Configuring]].

For example: 
* use powerplay option to switch power state for battery friendly or performance mode
* use dual head or one big desktop mode
* turn second monitor on/off on the fly

==Specific Issues==

=== 3D desktop effects ===
The new ATI drivers use AIGLX so there is not need to install XGL that older drivers (< 8.40) required.

Remove this section from to the /etc/X11/xorg.conf file.
The new xorg server enables "Composite" by default.
<pre>
# Section "Extensions"
# Option "Composite" "0"
# EndSection
</pre>

Compiz does not know about the fglrx driver. You can either skip the checks

<pre>mkdir -p ~/.config/compiz && echo SKIP_CHECKS=yes >> ~/.config/compiz/compiz-manager</pre>

or add it to the compiz white list, and clear the blacklist pci Ids variable '''*Recommended*'''

<pre>sudo gedit /usr/bin/compiz</pre>

<pre>
# Driver whitelist
WHITELIST="fglrx nvidia intel ati radeon i810"
</pre>

<pre>
# blacklist based on the pci ids
# BLACKLIST_PCIIDS="$T"
BLACKLIST_PCIIDS=""
</pre>

You might have to modify the path for line 30 and 31
<pre>
COMPIZ_BIN_PATH="/usr/bin/" # For window decorators and compiz
PLUGIN_PATH="/usr/lib/compiz/"
</pre>
The COMPIZ_NAME on line 35 should also be modified accordingly
<pre>
COMPIZ_NAME="compiz.real" # Final name for compiz (compiz.real)
</pre>

After the necessary configurations, just restart X and enjoy the cool effects.

If it still does not work, locate /etc/xdg/compiz/compiz-manager.ubuntu [this line may instead be in /etc/xdg/compiz/compiz-manager] and see if it contains an infinite loop in it. If it does, comment out the line that causes the infinite loop.
<pre>
# . /etc/xdg/compiz/compiz-manager.ubuntu
</pre>

For Kubuntu you need some extra steps:
<pre>
sudo apt-get install compiz compiz-kde compizconfig-settings-manager compiz-core compiz-fusion-plugins-main compiz-plugins
</pre>

To test 3D Effects, press ALT+F2 and type "compiz --replace".

To configure use the tool KMenu->Settings->Avanced Desktop Effect Settings.

=== Suspend/Hibernation work with 7.12===

With Gutsy release, there was a big problem using the ATI proprietary drivers. The Suspend/Hibernate function stopped working. The problem was due to the new SLUB allocator incorporated in 2.6.22 / 2.6.23 Kernel.

'''The problem has been solved in the AMD Catalyst 7.12 driver release.'''
'''UPDATE: The problem has NOT been solved in the AMD Catalyst 7.12 driver release.'''

Suspend/hibernate is not working for FireGL 5250.
For FireGL 5200, suspend works with the 7.12 fglrx kernel module loaded (which did not work before this release) , but does not work if X is running.

For Thinkpad T60 with ATI X1400, to get the laptop to wake up from suspend, I had to change the following in /etc/default/acpi-support:

SAVE_VBE_STATE=false

POST_VIDEO=false

Even with the above settings (like POST_VIDEO=false, etc.) my ASUS Z96J with an X1600 does not suspend.

This bug has been a serious issue for several months now. There is a lot of frustration over this, because Ubuntu/Canonical has not been helpful. They've said things like suggesting not using fglrx (thanks a lot, that really helps).

Current status on this bug can be found here: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/121653/

===If you get /usr/X11R6/lib/modules/dri/fglrx_dri.so not found===

sudo ln -s /usr/lib/ /usr/X11R6/lib/modules

It may be necessary to create the /usr/X11R6/lib directory first:

sudo mkdir /usr/X11R6/lib

===If you get /usr/X11R6/lib64/modules/dri/fglrx_dri.so not found===

sudo ln -s /usr/lib/ /usr/X11R6/lib64/modules

===Segmentation Fault with glxinfo/fglrxinfo===
If <code>fglrxinfo</code> or <code>glxinfo</code> returns a Segmentation fault like this:
<pre>
$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon Xpress Series
OpenGL version string: 1.4 (2.1.7170 Release)

Segmentation fault
</pre>

Set output of libGL to verbose with
<pre>$ export LIBGL_DEBUG=verbose</pre>

Run <code>fglrxinfo</code> or <code>glxinfo</code> again
<pre>libGL: XF86DRIGetClientDriverName: 8.44.3 fglrx (screen 0)
libGL: OpenDriver: trying /usr/lib/dri/fglrx_dri.so

display: :0.0 screen: 0

OpenGL renderer string: ATI Radeon Xpress Series
OpenGL version string: 1.4 (2.1.7170 Release)

Segmentation fault</pre>

Don't know if its always fglrx_dri.so, but the fix is to add read permissions to the file.

Check if read permission is not there
<pre>ls -l /usr/lib/dri/ |grep fglrx_dri
-rw-rw---- 1 root root 17462688 2008-01-13 17:42 fglrx_dri.so
</pre>

Add read permission
<pre>$ sudo chmod +r /usr/lib/dri/fglrx_dri.so</pre>

Check read permission
<pre>ls -l /usr/lib/dri/ |grep fglrx_dri
-rw-rw-r-- 1 root root 17462688 2008-01-13 17:42 fglrx_dri.so
</pre>

=== libGL error ===
* fglrxinfo gives: libGL.so.1: cannot open shared object file.
* Check the permission of the libGL.so.1.2 file with command:
ls -l /usr/lib/libGL*
* The file permission of libGL.so.1.2 should be "-rw-rw-r--". If the permission reads "-rw-rw----", do command
sudo chmod o+r /usr/lib/libGL.so.1.2
* If the permission is correct, fixed with command:
sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so.1

=== Monitor detection (1680x1050 Resolution Issue)--- SOLVED ===

As specified in the release notes, "Connecting a display device that supports 1680x1050 to a system running Linux may result in a
maximum display resolution of 1280x1024 only being available". (from [http://ubuntuforums.org/showthread.php?t=645974 thread])

['''It works with the latest driver''']

Fglrx driver does not detect some monitors correctly, so you have to do it manually (google about your monitor spec with keyword: xorg.conf).

'''For example:''' Samsung 205BW 1680x1050 monitor needs manually set:
{{Box File|/etc/X11/xorg.conf|
<pre>
Section "Monitor"
Option "DPMS"
Identifier "samsung-monitor"
VendorName "Samsung"
ModelName "SyncMaster 205BW"
HorizSync 31.4 - 80.0
VertRefresh 56.000 - 75.000
Modeline "1680x1050" 146.25 1680 1784 1960 2240 1050 1053 1059 1089
EndSection

Section "Screen"
Identifier "samsung-screen"
Device "samsung-device"
Monitor "samsung-monitor"
Defaultdepth 24
SubSection "Display"
Depth 24
Modes "1680x1050"
EndSubSection
EndSection
</pre>
}}

=== A possible problem with fglrx.ko conflicts ===

NOTE: I've run into strange problem building fglrx-kernel-source_8.443.1-1_i386.deb. If pentium-builder is installed, dkms fails to build fglrx.ko for make error (mixed implicit and static pattern rules. Stop.). It is caused by gcc.real and other indirections and wrong gcc version detection. Removing pentium-builder cures the problem.

It's necessary, because sometimes this file is written by other packages, and so there's no 3D acceleration.
Check that the file /lib/modules/$(uname -r)/misc/fglrx.ko has been created.

''Create the following folder''

<pre>
sudo mkdir /lib/modules/$(uname -r)/volatile
</pre>

Note: the volatile directory might already exist at this stage then simply continue with the next step.

''Create a symbolic link''

<pre>
sudo ln -sf /lib/modules/$(uname -r)/misc/fglrx.ko /lib/modules/$(uname -r)/volatile/fglrx.ko
</pre>

NOTE : On my Gutsy install, after a reboot this link was always removed automatically leaving me without an fglrx module loaded, and thus no ATI rendering. There have been several ways of getting around this suggested here, and here is the one that worked for me:

<pre>
sudo gedit /etc/init.d/ati-module-fix
</pre>

And put this in it:
<pre>
#!/bin/sh -e

# For loading ATI display drivers

ln -sf /lib/modules/$(uname -r)/misc/fglrx.ko /lib/modules/$(uname -r)/volatile/fglrx.ko
exit 0

</pre>

Make it executable

<pre>
sudo chmod ugo+x /etc/init.d/ati-module-fix
</pre>

Now, make this run ''before'' gdm

To check the gdm sequence number,
<pre>
ls /etc/rc2.d/
</pre>

The value for [seqno] in the section below should be the gdm sequence number -1.

<pre>
sudo update-rc.d ati-module-fix defaults [seqno]
</pre>

=== Hang at logout ===

If you experience hangs when logging out (of X) try disabling atieventsd with this command:

<pre>sudo /usr/sbin/update-rc.d -f atieventsd remove</pre>

== Revert to Xorg driver ==

If (for any reason) the fglrx install fails, you can revert to the Xorg driver by executing
<pre>sudo dpkg-reconfigure xserver-xorg</pre>
and selecting the "ati" driver, or simply restoring the previous /etc/X11/xorg.conf file, if you made a backup.

You also need to remove the xorg-driver-fglrx or your manually installed drivers to get the 3D acceleration back, since it is provided by file /usr/lib/libGL.so.1.2 which belongs to libgl1-mesa package and which is moved to backup and replaced at the installation of xorg-driver-fglrx (or the manually built) package. In case the removal of the fglrx drivers fails to restore the file from libgl1-mesa, you have to reinstall the package by running:

<pre>sudo apt-get install --reinstall libgl1-mesa-glx</pre>
