YoK4oX Thank you for your blog post.Really thank you! Really Cool.

= Alternative Manual Installation =
WARNING: This method is incompatible with Debian/Ubuntu Filesystem Hierarchy and may cause issues, especially when trying to remove or upgrade Catalyst. It is highly recommended to build .deb pakages. USE AT OWN RISK.

This is another method of manual installation that may work best for laptop users who have a hybrid setup (i.e. Intel HD onboard graphics with an AMD discrete GPU).

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orig
./amd-driver-installer-{{Catalystdashversion}}-x86/x86_64.run

Click "Install Driver on X.Org" rather than "Generate distribution specific driver package". Select the "Automatic" install option.

= Hardware Video Decode Acceleration (EXPERIMENTAL) =

== Using XBMC player (XvBA) ==

XBMC has added support for accelerating video using XvBA/libxvba directly, but the support is currently not in the xbmc package in Ubuntu's repositories. To install the XvBA-enabled version of xbmc:

sudo apt-add-repository ppa:wsnipex/xbmc-xvba
sudo apt-get update
sudo apt-get install xbmc
sudo amdconfig --set-pcs-u32=MCIL,HWUVD_H264Level51Support,1

== Using the xvba-va Driver (VA-API) ==
This is confirmed to work for newer RadeonHD GPU's (those with UVD2). If you have a RadeonHD 4000-series or newer, you have UVD2. To see the complete list: http://en.wikipedia.org/wiki/Unified_Video_Decoder#UVD_enabled_GPUs

sudo apt-get install xvba-va-driver libva-glx1 libva-x11-1 vainfo
vainfo

vainfo should return something like the following (and no errors):
libva: libva version 0.32.0
Xlib: extension "XFree86-DRI" missing on display ":0.0".
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/dri/fglrx_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA API version: 0.32
vainfo: Driver version: Splitted-Desktop Systems XvBA backend for VA-API - 0.7.8
vainfo: Supported profile and entrypoints
VAProfileH264High : VAEntrypointVLD
VAProfileVC1Advanced : VAEntrypointVLD

If vainfo returns an error, you may need to create a symlink:

sudo ln -s /usr/lib/va/drivers/fglrx_drv_video.so /usr/lib/x86_64-linux-gnu/dri/fglrx_drv_video.so #for 64-bit
sudo ln -s /usr/lib/va/drivers/fglrx_drv_video.so /usr/lib/dri/fglrx_drv_video.so #for 32-bit

Once you've confirmed that vainfo is correct, you can test video playback. A good test player for xvba is VLC. You can enable xvba in Tools -> Preferences -> Input and Codecs. Check the box named "Use GPU acceleration (experimental)" and then restart VLC.

=Updating Catalyst/fglrx=

DO NOT try to install a new version over an old one. Follow the 'Removing Catalyst/fglrx' section below to remove your existing driver, and then you can start at 'Downloading the latest Catalyst' to install the new one.

=Removing Catalyst/fglrx=
The uninstall script in the first command will only exist if you downloaded the drivers and installed them directly (rather than building packages as this guide does). Skip the first command if it does not exist.
sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*

If you plan on using open-source drivers, you will need to reinstall some packages because Catalyst overwrites or diverts some key 3D libraries with proprietary versions. For more information on this issue, see [https://wiki.ubuntu.com/X/Troubleshooting/FglrxInteferesWithRadeonDriver this Ubuntu wiki page]
sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon
sudo apt-get install xserver-xorg-video-ati
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
sudo rm -rf /etc/ati

If you receive

$ E: Internal Error, No file name for libgl1-mesa-dri

Change the third command above to:

sudo apt-get install --reinstall libgl1-mesa-glx:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:i386 libgl1-mesa-dri:amd64 xserver-xorg-core

= Issues =

== Video Tearing ==

AMD/ATI claims that the "Tear Free Video" option is enabled by default, but that wasn't the case with Catalyst 12-3 installed on Kubuntu 12.04.
If you're having issues with tearing, make sure that "Tear Free Video" is on. You can find this option in the Catalyst Control Center under 'Display Options' or you can use the following command:
sudo amdconfig --sync-video=on
The option will not take effect until you restart X (i.e. log out).

If you're using compositing, you should also make sure that vsync is enabled in the compositor's settings. I found that vsync was enabled by default, but here are the appropriate settings should you want to experiment.

=== kwin ===
You can enable vsync for kwin in System Settings -> Desktop Effects -> Advanced tab

=== Compiz (Unity/GNOME-Shell) ===
TODO: See if there's a friendlier way to make sure vsync is enabled without installing ccsm.

Install the compiz settings manager:
sudo apt-get install compizconfig-settings-manager
ccsm

The 'Sync to Vblank' is found in the 'OpenGL' subsection of the 'General' group

== Hybrid Graphics and Catalyst==

There are two basic types of hybrid designs. Older hybrid systems use a multiplexor (mux) to switch between GPU's. Newer systems (those with PowerXpress >= 4.0) are muxless. As far as I can tell, PowerXpress 4.0 started with RadeonHD 6000-series GPU's, and systems with older ATI GPU's have a mux, but don't quote that.

=== ATI/ATI Hybrids ===
As of Catalyst 11-8, switching between two ATI cards (and maybe Intel/ATI muxless too?) is supposed to be doable, though I don't know if that applies to all ATI/ATI hybrids or only the muxless ones. One would use amdconfig's PowerXpress options to switch back and forth between the integrated and discrete cards, like so:

amdconfig --pxl # List current activated GPU
sudo amdconfig --px-dgpu # Activate discrete GPU (High-Performance mode), must re-start X to take effect
sudo amdconfig --px-igpu # Activate integrated GPU (Power-Saving mode), must re-start X to take effect

After switching, one would log out and back in to restart X.

=== Intel/ATI Hybrids ===

Follow GUI Installation and choose the basic one "ATI/AMD proprietary FGLRX graphics driver". Let the install finish and it will ask you to reboot. Do not REBOOT.

Make a backup of your xorg.conf.

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orig

Generate a new config:

sudo amdconfig --initial -f

Force use of the new xorg.conf.

sudo amdconfig --input=/etc/X11/xorg.conf --tls=1

Run the following commands to confim your new settings:

fglrxinfo

and

fgl_glxgears

Once all done, Reboot.

Relogin and try the following command to see your Graphics card status:

sudo lshw -C display

Re-open "Additional Drivers" settings and you will see "ATI/AMD proprietary FGLRX graphics driver" status as "This driver is activated and currently in use". Open "AMD Catalyst Control Center" to see more options.

Tested on my Intel Gen 2/RadeonHD7550 gfx cards on a Samsung NP530U4B-S01AU Laptop. This solved a general overheating and crashing of AMD Catalyst Control Center issues.

Extra: I completely solved overheating issue with Jupiter Applet. (http://www.webupd8.org/2010/07/jupiter-ubuntu-ppa-hardware-and-power.html) on the same laptop. More comments on this would be appreciated.

== Build Fails and Log Shows "mixed implicit and normal rules. Stop." ==

If the installation fails and you find the above message in /var/lib/dkms/fglrx/<version_number>/build/make.log, it may be because you're using a pentium-build wrapper around gcc. See what the following ls command returns:
ls -la /usr/bin/gcc
If it shows that gcc is a link to builder-cc, temporarily redirect the link to point to the real gcc (gcc-4.6 in Ubuntu Precise). This should allow you to install fglrx:
sudo ln -sf /usr/bin/gcc-4.6 /usr/bin/gcc
When you're finished installing the driver, return the gcc link to its original value:
sudo ln -sf /usr/bin/builder-cc /usr/bin/gcc
Launchpad link for this bug: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/555957

== "Errors were encountered while processing: fglrx-amdcccle" (on 64-bit systems) ==
Most likely, you probably did not have the ia32-libs-multiarch:i386 lib32gcc1 libc6-i386 packages installed beforehand. 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, use the following command, which will force the installation of all of the 32 bit dependencies, and then the amdcccle package:

sudo apt-get -f install

Catalyst {{Template:Catalystversion}} on 64-bit systems may require the ''--force-overwrite'' command in the above ''dpkg'' command:
sudo dpkg -i --force-overwrite fglrx*.deb

== Problems Starting Xserver ==

If you get a black screen hang, the first thing to check is if xorg.conf is the problem.

You can disable the xorg.conf with:
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.disabled

Reboot and check to see if things work now.

You can reinstate the file with:
sudo mv /etc/X11/xorg.conf.disabled /etc/X11/xorg.conf

Before tweaking ACPI settings, try ensuring /dev/null is chmodded to 0666. This intermittently changes when using the nano (and possibly other) editors with sudo and the group/world permissions are unset. This leads to the ATI drivers hanging on boot or otherwise. A quick and dirty init script saved as /etc/init/chmodnull does the trick -

start on filesystem

script
chmod 0666 /dev/null
chmod 0666 /lib/udev/devices/null
end script

This has been tested using Ubuntu 10.04 64-bit on a ATI Radeon HD 4830 (HP Envy 15-1060ea). It's worth noting that I had to disable TLS (amdconfig --tls=0) to get things to stay stable!

If you've properly installed the driver, but experience problems when starting the X server, such as hanging, black/white/gray screen, distortion, etc., your system BIOS may have a buggy ACPI implementation. To work around, press Ctrl+Alt+F1 to get to a terminal (or failing that, boot to recovery mode) and run:
sudo amdconfig --acpi-services=off
If this method works, you should consider checking your system vendor's BIOS changelogs for relevant ACPI fixes, updating your BIOS, and reenabling the driver's ACPI services.

== Unsupported Hardware Watermark ==
This can happen if your card's PCI ID wasn't officially certified to work with a particular version of Catalyst. It does not necessarily mean that your card is unsupported, but it does mean that you shouldn't file bugs with that particular card/driver combination. If you installed the driver by downloading it from AMD/ATI, installing a newer version of Catalyst will probably help.

If you installed the proprietary driver included with Ubuntu or you do not want to upgrade to a newer version, it may be possible to work around the issue by using a control file from a older version of Catalyst than the one you're running.
cd ~/; mkdir catalyst12.4; cd catalyst12.4/
wget <nowiki>http://www2.ati.com/drivers/linux/amd-driver-installer-</nowiki>12-4-x86.x86_64.run
chmod +x amd-driver-installer-12-4-x86.x86_64.run
sh amd-driver-installer-12-4-x86.x86_64.run --extract driver
sudo mv /etc/ati/control ~/control.bak
sudo cp driver/common/etc/ati/control /etc/ati

== 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 authorization 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.

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

cd ~/catalyst{{Catalystversion}}
sh amd-driver-installer-{{Catalystversion}}-x86.x86_64.run --extract driver
sudo cp driver/packages/Ubuntu/dists/lucid/replacements/authatieventsd.sh /etc/ati/authatieventsd.sh
sudo chmod +x /etc/ati/authatieventsd.sh

This problem can be fixed permanently with:

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

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

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

You'll have to restart for this to take effect.

== Can't remove fglrx with dpkg (diversion issue) ==

If dpkg refuses to remove an fglrx package and complains about a diversion of a file, you might need to manually remove it. For example, if dpkg complains:
<pre>dpkg-divert: mismatch on divert-to
when removing `diversion of /usr/lib/libGL.so.1.2 to /usr/share/fglrx/diversions/libGL.so.1.2 by xorg-driver-fglrx'
found `diversion of /usr/lib/libGL.so.1.2 to /usr/lib/fglrx/libGL.so.1.2.xlibmesa by xorg-driver-fglrx'</pre>
then:
sudo dpkg-divert --remove /usr/lib/libGL.so.1.2

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

If you get this error-message, simply uninstall the previous version before installing the new one with:
sudo dkms remove -m fglrx --all

== New kernel installed? ==
In theory, DKMS should automatically install the fglrx kernel module for your new kernel the first time you boot it. Should you need to manually install it:
sudo dkms build -m fglrx -k `uname -r`
sudo dkms install -m fglrx -k `uname -r`

if amdcccle doesn't work and says Identifier is not a valid word. Use lower case letter in xorg.conf
[[Category:Installation Documentation]]

== amdconfig not found after installation ==
This scenario is possible when the driver installation has seemingly succeeded and is possibly related to previous fglrx installs, including those through Jockey (i.e. you first used drivers provided by Ubuntu but then upgraded to ones available from AMD's website). When doing amdconfig --initial after driver installation, you might end up not having the amdconfig available at all:
<pre>amdconfig: command not found</pre>
After booting you might receive X error '(EE) Failed to load module "fglrx" (module does not exist, 0)'. These do not necessarily indicate that the installation has failed completely. On command line, do
ls /usr/lib/fglrx/bin
and see if the command lists some Ati related programs. If they are listed but not found from /usr/bin, it is possible that the "update-alternatives" fglrx .deb installation does has been ignored. See man update-alternatives for more information about the concept and workings of alternatives. In practice, update-alternatives is supposed to create several symbolic links to the files in the fglrx directory, but it will be ignored if the alternatives for the very related gl_conf entry has been set to manual. Do
update-alternatives --get-selections | grep gl_conf
and see if the mode is manual instead of auto and if mesa is mentioned instead of fglrx in the path that is printed. In this case you need to
sudo update-alternatives --set gl_conf /usr/lib/fglrx/ld.so.conf
to set fglrx as the active alternative. You can alternatively (no pun intended) and additionally change the gl_conf into automatic mode before the installation this way:
sudo update-alternatives --auto gl_conf
After that, the alternatives should automatically be configured correctly when the graphics driver .debs are installed.

== "update-alternatives: error" during install ==
During installation you may receive the following message:
<pre>update-alternatives: error: unable to make /usr/lib/xorg/modules/drivers/fglrx_drv.so.dpkg-tmp a symlink to /etc/alternatives/fglrx_drv: No such file or directory</pre>
This can be easily solved by creating directory "drivers" under /usr/lib/xorg/modules/
sudo mkdir /usr/lib/xorg/modules/drivers

== 'Can't exec "debian/rules": Permission denied at /usr/bin/dpkg-buildpackage line 507.' during deb generation ==
During installation you may receive the following message:
<pre>Can't exec "debian/rules": Permission denied at /usr/bin/dpkg-buildpackage line 507.</pre>
This can happen when your /tmp folder is mounted with the option "noexec". The noexec is suggested by many howtos regarding Ubuntu on SSD, when placing the /tmp in memory.
A workaround can be found here: [http://serialized.net/2010/03/getting-around-tmpfs-noexec-problems/]

== Errors during deb generation ==
You may recieve errors if you do not have devscripts, dh-make, execstack and dh-modaliases installed. Run apt-get to install, and the errors go away and the deb is generated correctly.

If you recieve the error dpkg-buildpackage: not found:
sudo apt-get install devscripts

If you recieve the error make: dh: command not found:
sudo apt-get install dh-make

If you recieve the error make: execstack: Command not found:
sudo apt-get install execstack

If you recieve the error make: dh_modaliases: Command not found:
sudo apt-get install dh-modaliases

== Black screen after uninstalling old amd drivers ==
Start you computer in recovery mode and exit to root shell.
Remount your partitions in rw mode:
mount -rw -o remount /
...
Go to your download directory and proceed with building and installing the drivers in recovery mode.
All should be fine after a reboot.

= Minimal X.Org server configuration =
Once installed the two indicated packages, you must tell to the X.Org server to use ATI proprietary drivers, to do this we must check if the xorg.conf file, which is usually located in the ''/etc/X11/'' directory, contains the following items:

Section "Module"
...
Load "dri"
Load "glx"
...
EndSection

Section "Device"
...
Driver "fglrx"
...
EndSection

Section "DRI"
Group 0
Mode 0666
EndSection

{{Useful Information|Note|The command:
#> aticonfig --initial
can help you. Do '''aticonfig''' without options for more infos.}}

= Installation checking =
To see if proprietary ATI drivers are properly installed run the command:
$> fglrxinfo
On my computer the output is:
display::0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Mobility Radeon X1400
OpenGL version string: 2.0.6650 (8.39.4)

= Remove installed packages =
== ATI Proprietary drivers or ATI Catalyst < 11.3 ==
To remove installed packages you can use the '''removepkg''' utility. However, there are aspects that should be considered:
* The packages' removing don't delete fglrx's driver configuration files, these files are located in ''/etc/ati'' directory
{{Be Careful|Be Careful|The /etc/ati/custom-package directory, if exists, contains the '''external SlackBuild''' and therefore should not be deleted.}}
* The fglrx-x package contains ATI's OpenGL libraries, and these libraries are located in the same directory of the Mesa libraries, so when you install the fglrx-x package Mesa OpenGL libraries are overridden. To restore the situation you should simply reinstall the package containing these libraries, like:
::x11
:for Slackware 11, or:
::mesa
:for Slackware 12.

== ATI Catalyst >= 11.3 ==
During installation of the package ''fglrx-<version>-<architecture>-<release>.tgz'' some libraries that would be overwritten are renamed as FGL.renamed.library_name. Due to remove this package “cleanly” you should do:
#> aticonfig --uninstall
or, directly with the script:
#> /usr/share/ati/amd-uninstall.sh
or, also with any installer >= 11.3, with:
#> ati-driver-installer-<versione>-x86.x86_64.run --uninstall
Will remain only the directory ''/etc/ati'' with the configuration files.

= Patching the drivers =
Ati drivers are usually not compatible with brand new version of kernel linux. You often need to patch the driver so that you can create the kernel module successfully. Since Ati Catalyst > 8.11 you can patch Ati drivers within the '''internal SlackBuild''' before that same SlackBuild compiles the kernel module.

In order to do that, you just have to create (or download from the Internet) a patch and rename it like this:

''/etc/ati/patch/patch-ATI_DRIVER_VERSION-KERNEL_VERSION''

where:

ATI_DRIVER_VERSION must be equal to the output of:
$> sh ati-driver-installer-<version>-x86.x86_64.run -i | head -n1 | cut -d'-' -f2
KERNEL_VERSION must be equal to the output of:
$> uname -r

If ''/etc/ati/patch'' doesn't exist, it must be made.

For example, if the former command outputs "8.55" and the latter "2.6.27.6", you need to name the patch ''/etc/ati/patch/patch-8.56-2.6.27.6''.

The '''internal SlackBuild''' will find the patch automatically and, if the command '''patch''' is installed, it will run:
#> patch -p0 < /etc/ati/patch/patch-8.56-2.6.27.6

== Patches ==
Here some patches and how to use there:

You need to enable the '''Big Kernel Lock''' in your kernel configuration. You find it under the '''Kernel hacking''' menu. You can check if this option is enable with:
$> zcat /proc/config.gz | grep BKL
CONFIG_BKL=y

== FATAL: modpost: GPL-incompatible module fglrx.ko uses GPL-only symbol 'paravirt_ops' ==
The error occurs during module compilation and It's due to the fact that the kernel was compiled with the option of paravirtualization active. This option among other things, prevents to load, and then to compile, modules that do not have the GPL license. Since that ATI drivers don't have this type of license, they aren't compiled.

To work around this problem you can:
==== Disable kernel paravirtualization option ====
The paravirtualization option is called '''CONFIG_PARAVIRT''' and generally is in the '''Processor type and features''' kernel submenu.
==== Patch ATI drivers ====
This operation is illegal because It changes the type of license issued by ATI in a GPL license. I wrote the patch:

[http://www.slacky.eu/~spina/fglrx/patch/ati_to_gpl.patch ati_to_gpl.patch] (md5sum: 4207f41a71035dc2eed3ea9346b881bb)

but I do not take any responsibility, I do not use It and I discourage the use in order to prefer the alternative to disable the paravirtualization kernel option. To use this patch You need to:

'''External SlackBuild'''
* Copy the patch in the ''/etc/ati/custom-package/patch'' directory

'''Internal SlackBuild''' (only with Ati Catalyst > 8.11):
* Copy the patch in the ''/etc/ati/patch'' directory (if it doesn't exist you must create it)

The SlackBuild will find and apply the patch automatically. In order to uninstall it you simply need to delete it. In order to uninstall the patch simply delete It from ''/etc/ati/custom-package/patch'' directory.

== Using GLX_SGIX_pbuffer FGLTexMgr: open of shared memory object failed (Permission denied) __FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!! ==
This problem is due to the lack of SHM filesystem (now called tmpfs), that is virtual memory filesystem. To work around this problem you must:
* Add into ''/etc/fstab'' file the following line:
shm /dev/shm tmpfs defaults 0 0
* Then mount the filesystem through:
#> mount /dev/shm
Obviously the kernel must be predisposed for the "mounting" of this filesystem, in particular the kernel option that must be enabled is '''CONFIG_TMPFS''' that is generally placed in '''File system --> Pseudo filesystems''' submenu. However all the compiled kernel generally have this option enabled.

== kernel includes at /lib/modules/`uname -r`/build/include do not match current kernel ==
The complete mistake is something like this:

Error:
kernel includes at /lib/modules/`uname -r`/build/include do not match current kernel.
they are versioned as ""
instead of "`uname -r`".
you might need to adjust your symlinks:
- /usr/include
- /usr/src/linux

The error, also if explained, could be not clear. In practice It results from the fact that the symbolic link:
/lib/modules/`uname -r`/source
/lib/modules/`uname -r`/build
don't point to the directory where are inserted the current kernel sources (which is generally ''/usr/src/linux- 'uname-r'''). It happens to those who use a kernel contained in Slackware, so I will try to explain It in terms of Slackware "packages". This can happen:
* because the kernel source were not installed. In this case should be enough to install the source package which can be found in Slackware k/ directory. However, It is not granted that the problem will be solved, You'll need to see the second reason why there is an error.
* because sources (also if installed) do not reflect the settings of the current kernel. The new Slackware 12 has some precompiled kernels (which means different settings), while just a single package for the sources (unless seeing the branch extra/). In particular, the sources are for the SMP kernel and so if you use a non-SMP kernel can appear this error. To avoid this, after making sure that the package source has been installed, do simply the following:
#> cd /usr/src/linux
#> cp /boot/config .config
#> make
:running make, in addition to compiling the kernel modules (which we will not use), some header files are regenerated, and they will reflect the kernel configuration (as it's set in the .config file).

== Driver 8.39.4 logo ==
This "bug" in 8.39.4 drivers results from the fact that ATI developers don't update the packager maintainers before the official releases. It should be nice first if they did test us official releases in order to certify the proper functioning of the scripts for creating packages. To solve the problem it's necessary to use the '''external SlackBuild''' as described here.

== amdcccle don't start on Slackware 12 ==
Many users of the X.Org 7.2 (or 1.3) server version fail to start properly the Catalyst. The command to run the Catalyst is:
#> amdcccle
For this problem it seems there is no solution yet, but we are working on to solve it.
