AMD's Linux driver package ''catalyst'' was previously named ''fglrx'' ('''F'''ire'''GL''' and '''R'''adeon '''X'''). Only the package name has changed, while the kernel module retains its original ''fglrx.ko'' filename. Therefore, any mention of fglrx below is specifically in reference to the ''kernel module'', '''not the package'''.

<strike>Catalyst was once a precompiled package offered by Arch in the [extra] repository, but as of March 2009, official Arch support [https://www.archlinux.org/news/ati-catalyst-support-dropped/ has been dropped] because of dissatisfaction with the quality and speed of development</strike>. In October 2012, it seems like the packages are being offered again. Currently, packages are available in the [community] repository, but it's unknown what will happen when an Xorg upgrade will break the driver. Also, a legacy driver for Radeon HD 2xxx 3xxx 4xxx is not available yet. For more information, see [https://bbs.archlinux.org/viewtopic.php?pid=1166052#p1166052/ this] this forum post and onwards.

'''Catalyst packages are no longer offered in the official repositories.''' In the past, Catalyst [https://www.archlinux.org/news/ati-catalyst-support-dropped/ has been dropped] from official Arch support because of dissatisfaction with the quality and speed of development. After a brief return they were dropped again in April 2013 and they have not returned since.
  
Compared to the open source driver, Catalyst performs worse in 2D graphics, but has a better support for 3D rendering. Supported devices are [[wikipedia:Radeon|ATI/AMD Radeon]] video cards with chipset R600 and newer (as of Catalyst 9.4). See [[wikipedia:Comparison_of_AMD_graphics_processing_units|this table]], or the Xorg [http://www.x.org/wiki/RadeonFeature#Decoder_ring_for_engineering_vs_marketing_names "Decoder ring",] to translate ''model'' names (X1900, HD4850) to/from ''chip'' names (R580, RV770 respectively).

Compared with the open source driver, Catalyst performs better in both 2D and 3D rendering, also having better power management, but it lacks efficient multi-head support. Supported devices are [[wikipedia:Radeon|ATI/AMD Radeon]] video cards with chipset R600 and newer (Radeon HD 2xxx and newer). See the Xorg [http://www.x.org/wiki/RadeonFeature/#index5h2 decoder ring] or [[wikipedia:Comparison of AMD graphics processing units|this table]], to translate ''model'' names (X1900, HD4850) to/from ''chip'' names (R580, RV770 respectively).

There are four ways of installing Catalyst on your system. One way is to use the official [community] repository, but this does not contain all the packages just yet. (At this time of writing, October 2012, there's no xvba-video and lib32 driver yet. Also, a legacy driver is still missing). Another one is to use Vi0L0's (Arch's unofficial Catalyst maintainer) repository. This repository does contain all the necessary packages. The third method you can use is the AUR; PKGBUILDs offered here are also made by Vi0L0 and are the same he uses to built packages for his repository. Lastly, you can install the driver directly from AMD.

Lastly, you can install the driver directly from AMD.
  
Before choosing the method you prefer, you will have to see which driver you need. Since Catalyst 12.4, AMD has separated its development for Radeon HD 5xxx and Radeon HD 2xxx, 3xxx and 4xxx cards. For Radeon HD 2xxx, 3xxx and 4xxx cards, there's the '''legacy''' Catalyst driver, for Radeon HD 5xxx there is the regular Catalyst. Regardless of the driver you need, you will also need the Catalyst utilities.

==== Installing from the official repository ====
 
This is the most simple and straightforward way, as it requires no unofficial repositories and because this package uses [[Dynamic Kernel Module Support|DKMS]] to automatically rebuilt the kernel modules when the kernel is upgraded. If this repository holds the packages you need, I suggest you take this one.
 
 
To install Catalyst, you can use [[Pacman|pacman]]:
 
 
# pacman -S catalyst-dkms catalyst-utils
 
 
{{Note|Don't forget to install {{Pkg|linux-headers}} for [[Dynamic Kernel Module Support|DKMS]] to function properly.}}
 
 
{{Note|If pacman asks you about removing '''libgl''' - you may safely say "Y"}}
 
 
{{Note|If you are using systemd, you should enable the DKMS service. SysV init users do not have to do this. For more information on enabling service files, see [[systemd]].}}
 
 
If you are on 64 bit and also need 32 bit OpenGL support, install lib32-catalyst-utils. Note that you will have to enable the [multilib] repository first.
 
 
# pacman -S lib32-catalyst-utils
 
 
Later on, a legacy driver will also be offered here.

==== Installing from the unofficial repository ====
If you need packages that currently aren't hosted by the official repository and don't fancy building the packages from the [[Arch User Repository|AUR]], this is the way to go. The repository is maintained by our unofficial Catalyst maintainer, Vi0L0. All packages are signed and I consider them safe to use. As you will see later on in this article, Vi0L0 is also responsible for many other packages that will help you get your system working with your ATI graphic cards.
 
  
Vi0L0 has two different Catalyst repositories, each having different drivers:

*[catalyst]; for the regular Catalyst driver needed by Radeon HD 5xxx and up.
+
*[catalyst-hd234k]; for the legacy Catalyst driver needed by Radeon HD 2xxx, 3xxx and 4xxx cards.  
+
  
{{Warning|The Legacy driver does not support Xorg 1.13 for now. Support should be added by AMD in a century or two, but this could be sooner. Should you want to use this driver, see [[#Xorg repositories]] for instructions on how to roll back to or hold back Xorg 1.12.}}
+
Vi0L0 has three different Catalyst repositories, each having different drivers:
 +
* [[Unofficial user repositories#catalyst|catalyst]] for the regular Catalyst driver needed by Radeon HD 5xxx and up, it contains the latest (stable or beta) Catalyst release.
 +
* ''catalyst-stable'' for the regular Catalyst driver needed by Radeon HD 5xxx and up, with the latest stable driver.
 +
* [[Unofficial user repositories#catalyst-hd234k|catalyst-hd234k]] for the legacy Catalyst driver needed by Radeon HD 2xxx, 3xxx and 4xxx cards.
  
To enable one of these, you will have to edit {{ic|/etc/pacman.conf}} and add the repository of choice's information '''above all other repositories in {{ic|/etc/pacman.conf}}:
+
To enable one of these, follow the instructions in [[Unofficial user repositories]]. Remember to add the chosen repository '''above all other repositories''' in {{ic|pacman.conf}}.
  
# nano /etc/pacman.conf
+
{{Note|The ''catalyst'' and ''catalyst-stable'' repositories share the same URL. To enable ''catalyst-stable'', follow the instructions for enabling ''catalyst'' and replace {{ic|[catalyst]}} with {{ic|[catalyst-stable]}} in {{ic|pacman.conf}}. If you need to stick with an old version, there are also some versioned repositories using the same URL (for example ''catalyst-stable-13.4'').}}
  
For [catalyst], it's this:

{{Tip|Because catalyst.wirephire.com will go down if a certain bandwidth limit is exceeded (this happened in the past) or may be too slow at your location, repository mirror is provided by goll at [http://mirror.hactar.bz/Vi0L0/] (DE). This mirror however come with no warranty and is not guaranteed to always be operational.

}}
  
[catalyst]
+
Once you have added some Catalyst repository, update pacman's database and [[install]] these packages (see [[#Tools]] for more information):
<nowiki>Server = http://catalyst.apocalypsus.net/repo/catalyst/$arch</nowiki>
+
  
For [catalyst-hd234k], you have to add the following:
+
* ''catalyst-hook''
 +
* ''catalyst-utils''
 +
* ''catalyst-libgl''
 +
* ''opencl-catalyst'' - optional, needed for OpenCL support
 +
* ''lib32-catalyst-utils'' - optional, needed for 32-bit OpenGL support on 64-bit systems
 +
* ''lib32-catalyst-libgl'' - optional, needed for 32-bit OpenGL support on 64-bit systems
 +
* ''lib32-opencl-catalyst'' - optional, needed for 32-bit OpenCL support on 64-bit systems
  
[catalyst-hd234k]
+
{{Note|If pacman asks you about removing '''libgl''' you can safely do so.}}
<nowiki>Server = http://catalyst.apocalypsus.net/repo/catalyst-hd234k/$arch</nowiki>
+
  
You must also [[User:Vi0L0|add Vi0L0's GPG key]] so that pacman trusts the repositories.
+
{{Warning|catalyst package was removed from Vi0L0's repository, its place was taken by catalyst-hook.}}
 
+
# pacman-key --keyserver pgp.mit.edu --recv-keys 0xabed422d653c3094
+
# pacman-key --lsign-key 0xabed422d653c3094
+
 
+
Once you have added this, update pacman's database and install the packages:
+
 
+
# pacman -Syu
+
# pacman -S catalyst catalyst-utils
+
 
+
{{Note|If pacman asks you about removing '''libgl''' - you may safely say "Y"}}
+
 
+
If you are on 64 bit and need 32 bit OpenGL support, install lib32-catalyst-utils. Note that you will have to enable the [multilib] repository first:
+
 
+
# pacman -S lib32-catalyst-utils
+
 
+
Both repositories also contain other packages, that can ''replace'' the Catalyst package and provide fglrx modules for ''multiple'' kernels that are installed on your system:
+
 
+
* Catalyst-generator; this package is able to generate fglrx modules packed into pacman compliant packages - most secure and KISS-compatible package in this side-note, although it has to be operated manually.
+
* Catalyst-hook; A hook for [[mkinitcpio|mkinitcpio]] which will automatically update fglrx modules with every kernel's update. '''This is basically the same as catalyst-dkms from [community]'''.
+
* Catalyst-daemon; this delivers an automatic update of the fglrx module with every kernel update, done by an init script. '''This is the same as Catalyst-hook and also catalyst-dkms from [community]. Also, systemd users have no use for this package, as systemd has no init script support'''.
+
 
+
You will find more details about those packages in [[#Tools| Tools section]].
+
Lastly, both repositories also contain the '''xvba-video''' package, which enables video acceleration described [[#Video_acceleration]] and the '''AMDOverdriveCtrl''' package, which is a GUI to control over- and underclocking. See [[#GPU/Mem frequency, Temperature, Fan speed, Overclocking utilities]]

The last way to install Catalyst is from the [[Arch User Repository|AUR]]. If you want to built the packages specifically for your computer, this is your way to go.

==== Installing directly from AMD ====
+
{{Warning|Using the installer from ati.com/amd.com is '''not''' recommended! It may cause file conflicts and X failures and you will miss Arch-specific fixes. You '''must''' be familiar with booting to the command-line if you wish to attempt this.}}
+
 
+
{{Note|If you have attempted a manual install from the official installer and cannot recover your desktop:
+
# /usr/share/ati/fglrx-uninstall.sh
+
}}
+
 
+
1.) Download the installer from AMD or elsewhere (whereas *-* will be the version): {{ic|ati-driver-installer-*-*-x86.x86_64.run}}
+
 
+
2.) Make sure it's executable: {{ic|# chmod +x ati-driver*}}
+
 
+
3.) Ensure you're using a basic video driver like vesa and remove conflicting drivers (i.e. {{ic|xf86-video-ati}}) with pacman.
+
 
+
4.) Symlink {{ic|/usr/src/linux}} to {{ic|<nowiki>/usr/src/{kernelsource}</nowiki>}}. 64-bit users also symlink{{ic|/usr/lib64}} to {{ic|/usr/lib}}.
+
 
+
5.) Be sure to have your build environment setup: {{ic|# pacman -Syu base-devel linux-headers}}
+
 
+
6.) Now run {{ic|# ./ati-driver-installer-*-*-x86.86_64.run}} (Files will extract to a temporary folder and scripts will run...)
+
 
+
Assuming nothing went horribly wrong...
+
 
+
7.) Check {{ic|/usr/share/ati/fglrx-install.log}} for issues. There should also be a {{ic|/lib/modules/fglrx/make.{ker_version}.log}}.
+
  
{{Note|If you modify the make scripts, save to a different filename. Otherwise uninstall will not complete successfully.}}
+
The {{AUR|catalyst-total}} packages are made to make the lives of AUR users easier. It builds the driver, the kernel utilities and the 32 bit kernel utilities. It also builds the {{AUR|catalyst-hook}} package, which is described in [[#Tools]].

==== Loading the module at boot ====
 
==== Loading the module at boot ====
How you should handle this depends on the init system you're using; either SysVinit or systemd. In either case, you have to blacklist ''radeon'' in {{ic|/etc/modprobe.d/modprobe.conf}}. For more information, see [[Modprobe|blacklisting in this article]]. '''Users of the [community] package do not have to do this, it's automatically done for them when installing the package'''.
+
We have to blacklist the {{ic|radeon}} module to prevent it from auto-loading. To do so, blacklist ''radeon'' in {{ic|/etc/modprobe.d/modprobe.conf}}. Also, make sure that it is not loaded by any file under {{ic|/etc/modules-load.d/}}. For more information, see [[kernel modules#Blacklisting]].  
  
{{Note|The systemd method is recommended, as Arch is slowly switching over to this and the rc.conf method is actually deprecated.}}
+
Then we will have to make sure that the {{ic|fglrx}} module gets auto-loaded. Either add {{ic|fglrx}} on a new line of an existing module file located under {{ic|/etc/modules-load.d/}}, or create a new file and add {{ic|fglrx}}.
 
+
===== The systemd method =====
+
* Disable the {{ic|radeon}} module from auto-loading. If it occurs in any file under {{ic|/etc/modules-load.d/}}, remove the file (or, if the file contains multiple modules, just remove the radeon one).
+
* Either add {{ic|fglrx}} on a new line of an existing module file located under {{ic|/etc/modules-load.d/}}, or create a new file and add {{ic|fglrx}}.
+
 
+
===== Arch initscripts =====
+
Edit {{ic|/etc/rc.conf}} by:
+
* Removing {{ic|radeon}} from the MODULES array.
+
* Adding {{ic|fglrx}} to MODULES.
+
 
+
{{Note|If you are using an AGP card instead of PCI Express add the ''agp'' module as well.}}

==== Disable kernel mode setting ====
 
==== Disable kernel mode setting ====
  
Disabling kernel mode setting is important, as the driver doesn't take advantage of [[KMS]] yet. If you do not deactivate KMS, your system might freeze when trying to switch to a tty or even when shutting down via your DE.
+
{{Note|Do not do this if you are using powerXpress technology (or hybrid AMD-Intel graphics) because Intel driver needs it.}}
  
For [[GRUB Legacy|GRUB Legacy]], edit {{ic|menu.lst}} by adding {{ic|nomodeset}} to the kernel parameters. For example:

+
To disable kernel mode setting, add {{ic|nomodeset}} to your [[kernel parameters]].
  
For [[GRUB2|GRUB 2]], edit {{ic|/etc/default/grub}} and add ''nomodeset'' to the kernel parameter options, e.g.
+
==== Checking operation ====
  
GRUB_CMDLINE_LINUX="nomodeset"
+
Assuming that a reboot to your login was successful, you can check if {{ic|fglrx}} is running properly with the following commands:
  
Then run, as root;
+
$ lsmod | grep fglrx
  
# grub-mkconfig -o /boot/grub/grub.cfg
+
If you get output, it works. Finally, run X manually with {{ic|$ startx}} or by using a display manager (see [[Xorg#Running]]).
  
For [[Syslinux|Syslinux]], edit {{ic|/boot/syslinux/syslinux.cfg}} and add ''nomodeset'' to the {{ic|APPEND}} line, e.g.:
+
The following command should output your graphic card model name:
  
APPEND root=/dev/sda2 ro ''nomodeset''
 
 
==== Checking operation ====
 
 
Assuming that a reboot to your login was successful, you can check if fglrx is running properly with the following commands:

==== Running two X servers (one using the Intel driver, another one using fglrx) simultaneously ====
 +
Because fglrx is crash-prone (regarding PowerXpress), it could be a good idea to use the Intel driver in the main X server and have a secondary X server using fglrx when 3D acceleration is needed. However, simply switching to the discrete GPU from the integrated GPU using {{ic|aticonfig}} or {{ic|amdcccle}} will cause all sorts of weird bugs when starting the second X.
 +
 +
To run two X servers at the same time (each using different drivers), you should firstly set up a fully working X with Catalyst and then move its {{ic|xorg.conf}} to a temporary place (for example, {{ic|/etc/X11/xorg.conf.fglrx}}. The next time X is started, it will use the Intel driver by default instead of fglrx.
 +
 +
To start a second X server using fglrx, simply move {{ic|xorg.conf}} back to the proper place ({{ic|/etc/X11/xorg.conf}}) before starting X. This method even allows you to switch between running X sessions. When you are done using fglrx, move {{ic|xorg.conf}} somewhere else again.
 +
 +
The only disadvantage of this method is not having 3D acceleration using the Intel driver. 2D acceleration, however, is fully functional. Other than that, this will provide us with a completely stable desktop.
 +
 +
==== Issues with PowerXpress laptops running in AMD mode (pxp_switch_catalyst amd) with external / secondary monitor ====
 +
When using a PowerXpress laptop in AMD-only mode (ie, setting the discrete card to render everything) you sometimes run into issues with artifacting/duplicating between displays. This is a known issue, and seems to effect 7xxxM series cards.
 +
 +
The artifacting disappears when you transform one of the monitors by either rotating or scaling. So you can use xrandr to fix this:
 +
 +
{{bc|1=
 +
xrandr --output HDMI1 --left-of LVDS1 --primary --scale 1x1 --output LVDS1 --scale 1.0001x1.0001

=== Catalyst-hook ===
 
=== Catalyst-hook ===
[https://aur.archlinux.org/packages.php?ID=40834 Catalyst-hook] is a hook for [[mkinitcpio|mkinitcpio]] that will automatically update fglrx modules with every kernel update. '''This is basically the same as catalyst-dkms from [community].''' Before updating the fglrx modules, it will first try to update the {{Pkg|linux-headers}}.
+
{{AUR|Catalyst-hook}} is a [[systemd]] service that will automatically rebuild the {{ic|fglrx}} modules while the system shuts down or reboots, but only if it is necessary (e.g. after an update).
  
The hook will call the ''catalyst_build_module'' command to update fglrx module for the version of your new kernel. Additionally, it can call the ''catalyst_build_module remove'' command to remove the now old and unneeded flgrx module(s).
+
Before using this package make sure that both the {{Grp|base-devel}} group and the {{Pkg|linux-headers}} package (the one specific to the kernel you use) are installed.
  
{{Note|If you are using this functionality it's '''important''' to look at the installation process of the linux kernel (or any other kernel) package. Catalyst-hook will tell you is everything all right.}}
+
To enable the automatic update, enable the {{ic|catalyst-hook.service}}:
  
{{Note|If your '''custom kernel''' is using some '''non-standard mkinitcpio configuration file''' (ie. linux-zen is using /etc/mkinitcpio-zen.conf) you'll have to manually add '''fglrx''' to HOOKS array in your non-standard configuration file so it can be auto-recompiled with a kernel update.}}
+
# systemctl enable catalyst-hook
 +
# systemctl start catalyst-hook
  
{{Note|If you '''aren't using the stock linux kernel''' at all and still want to use auto-recompilation, you should remove linux-headers from the {{ic|SyncFirst}} list of {{ic|/etc/pacman.conf}} after running 'catalyst_build_module auto'. If you also have custom linux-headers, you can swap linux-headers in the {{ic|SyncFirst}} line with your custom one, for example linux-lts-headers.}}
+
You can also use this package to build the {{ic|fglrx}} module manually. Simply run the {{ic|catalyst_build_module}} script after the kernel has been updated:
 +
 
 +
# catalyst_build_module all
 +
 
 +
'''A few more technical details:'''
 +
 
 +
The {{ic|catalyst-hook.service}} is stopping the systemd "river" and is forcing systemd to wait until catalyst-hook finishes its job.
 +
 
 +
The {{ic|catalyst-hook.service}} is calling the {{ic|catalyst_build_module check}} function which checks if fglrx rebuilds are really necessary.
 +
 
 +
The {{ic|check}} function is checking if the {{ic|fglrx}} module exists, if it:
 +
 
 +
*does not exist, it will build it;
 +
 
 +
*does exist, it will compare the two values to be sure that a rebuild is necessary.
 +
 
 +
These values are md5sums of the {{ic|/usr/lib/modules/<kernel_version>/build/Module.symvers}} file (because I, Vi0L0, noticed that this file is unique and different for every kernel's release). The first value is the md5sum of the existing {{ic|Module.symvers}} file. The second value is the md5sum of the {{ic|Module.symvers}} file which existed in a moment of the {{ic|fglrx}} module creation. This value was compiled into the {{ic|fglrx}} module by a {{ic|catalyst_build_module}} script.
 +
 
 +
If the values are different, it will compile the new {{ic|fglrx}} module.
 +
 
 +
The check is checking the whole {{ic|/usr/lib/modules/}} directory and building modules for all of the installed kernels if it is necessary. If the build or rebuild is not necessary, the whole process takes only some milliseconds to complete before it gets killed by systemd.

=== OpenCL and OpenGL development ===
 +
 
 +
Since years AMD is working on tools for OpenCL and OpenGL developement.
 +
 
 +
Now under the banner of '''"Heterogeneous Computing"''' AMD is providing even more of them, fortunately most of their computing tools are available also for Linux.
 +
 
 +
In the AUR and the [catalyst] repositories you will find packages that represent the most important work from AMD, namely:
 +
 
 +
* {{AUR|amdapp-aparapi}}
 +
* {{AUR|amdapp-sdk}}
 +
* {{AUR|amdapp-codexl}}
 +
 
 +
APP shortcut stands for Accelerated Parallel Processing.
  
'''WARNING:''' '.pkg' is not a valid archive extension.
+
==== amdapp-aparapi ====
 +
AMD's Aparapi is an API for expressing data parallel workloads in Java and a runtime component capable of converting the Java bytecode of compatible workloads into OpenCL so that it can be executed on a variety of GPU devices. If Aparapi can’t execute on the GPU, it will execute in a Java thread pool.

+
You can find more information about Aparapi [http://developer.amd.com/tools/heterogeneous-computing/aparapi/ here].
  
=== Catalyst-daemon ===
+
==== amdapp-sdk (formerly known as amdstream) ====
{{Warning| systemd users have no use for this, as systemd is not compatible with regular initscript daemons.}}
+
The AMD APP Software Development Kit (SDK) is a complete development platform created by AMD to allow you to quickly and easily develop applications accelerated by AMD APP technology. The SDK provides samples, documentation and other materials to quickly get you started leveraging accelerated compute using OpenCL, Bolt, or C++ AMP in your C/C++ application.
  
[https://aur.archlinux.org/packages.php?ID=40832 Catalyst-daemon] is, as its name suggests, a daemon that will run upon every boot to check if the kernel was updated. If it was, it will rebuild the fglrx module - if it wasn't, it will load the previously built fglrx module. This whole operation takes only 20ms on a 2.4 GHz CPU.
+
Since version 2.8 amdapp-sdk is providing aparapiUtil as well as aparapi's samples. A package is available on the [catalyst] repository; it depends on the {{AUR|amdapp-aparapi}} package. The AUR's package will let you decide whether you want aparapi's additions or not.
  
The automatic re-compilation functionality of Catalyst-daemon is done by an init script called ''autofglrx''. Autofglrx's check function is comparing the built time of the just booted kernel (provided by {{ic|uname -v}}) with the built time of a kernel for which the previously used fglrx module was built. It is able to do such a comparison because it adds {{ic|uname -v}} information to the fglrx module description whilst compiling it.  
+
Version 2.8 does not provide Profiler functionality, it has been moved to CodeXL.
  
Whilst rebuilding, autofglrx will call the ''catalyst_build_module'' to build a module and ''catalyst_build_module remove'' to remove the old, unneeded fglrx module. It doesn't remain in the system's memory after being run.
+

'''[[wikipedia:Video_Acceleration_API|Video Acceleration API]] (VA API)''' is an open source software library (libVA) and API specification which provides GPU acceleration for video processing on Linux/UNIX based operating systems. The process works by enabling hardware accelerated video decode at various entry-points (VLD, IDCT, Motion Compensation, deblocking) for common encoding standards (MPEG-2, MPEG-4 ASP/H.263, MPEG-4 AVC/H.264, and VC-1/WMV3).

VA-API gained a proprietary backend (in November 2009) called {{AUR|xvba-video}}, that allows VA-API programmed applications to take advantage of AMD Radeons UVD2 chipsets via the [[wikipedia:XvBA|XvBA (X-Video Bitstream Acceleration API designed by AMD)]] library.

== Uninstallation ==
 +
 +
If for any reason this driver is not working for you or if you simply want to try out the open source driver, remove the {{ic|catalyst}} and {{ic|catalyst-utils}} packages. Also you should remove {{AUR|catalyst-generator}}, {{AUR|catalyst-hook}} and {{AUR|lib32-catalyst-utils}} packages if they have been installed on your system.
 +
 +
{{Warning|
 +
*You may need to use {{ic|# pacman -Rdd}} to remove {{AUR|catalyst-utils}} (and/or {{AUR|lib32-catalyst-utils}}) because that package contains ''gl'' related files and many of your installed packages depend on them. These dependencies will be satisfied again when you install {{Pkg|xf86-video-ati}}.
 +
*You may need to remove {{ic|/etc/profile.d/ati-flgrx.sh}} and {{ic|/etc/profile.d/lib32-catalyst}} (if it exists on your system), otherwise {{ic|r600_dri.so}} will fail to load and you would not have 3D support.}}
 +
 +
{{Note|You should remove unofficial repositories from your {{ic|/etc/pacman.conf}} and run {{ic|# pacman -Syu}}, because those repositories include out-dated Xorg packages to allow use of {{ic|catalyst}} and the {{Pkg|xf86-video-ati}} package needs up-to-date Xorg packages from the [[Official repositories]].}}
 +
 +
Also follow these steps:
 +
 +
* If you have the {{ic|/etc/modprobe.d/blacklist-radeon.conf}} file remove it or comment the line {{ic|blacklist radeon}} in that file.
 +
* If you have a file in {{ic|/etc/modules-load.d}} to load the {{ic|fglrx}} module on boot, remove it or comment the line containing {{ic|fglrx}}.
 +
* Make sure to remove or backup {{ic|/etc/X11/xorg.conf}}.
 +
* If you have installed the {{AUR|catalyst-hook}} package, make sure to disable the systemd service.
 +
* If you used the {{ic|nomodeset}} option in your [[kernel parameters]] and plan to use KMS, remove it.
 +
* '''Reboot''' before installing another driver.

Seemed to be a feature by AMD/ATI to work with all HDTVs that could be adjusted via the amdccle.
  
Restart X server or reboot your system.
+
Using the amdcccle GUI you can select the affected display, go to adjustments, and set underscan to 0% (aticonfig defaults to 15% underscan). It is possible as well that the underscan slider will not show under the display's adjustments, as sometimes in (at least) version 14.10.
 +
 
 +
The problem is that the settings will not persist after restarting X server or rebooting or wake up or might even revert after changing TTYs.
 +
 
 +
For the changes to become permanent, you will need to adjust the underscan settings manually using "aticonfig" via console (as root) or manually edit the file {{ic|/etc/ati/amdpcsdb}} (as root)
 +
 
 +
'''using aticonfig method:'''
 +
 
 +
# aticonfig --set-pcs-u32=MCIL,DigitalHDTVDefaultUnderscan,0
 +
 
 +
After changing the settings, reboot.
 +
 
 +
For newer version (for example, 12.11), if Catalyst control center repeatedly fails to save the overscan setting you can also try:
 +
 
 +
# aticonfig --set-pcs-u32=MCIL,TVEnableOverscan,0
 +
 
 +
'''Manually editing /etc/ati/amdpcsdb method:'''
 +
 
 +
Add the following line anywhere under the following header {{ic|[AMDPCSROOT/SYSTEM/MCIL]}}
 +
 
 +
# DigitalHDTVDefaultUnderscan=V0
 +
 
 +
For newer version (for example, 12.11), if Catalyst control center repeatedly fails to save the overscan setting you can also try:
 +
locate under {{ic|[AMDPCSROOT/SYSTEM/MCIL]}} the following line
 +
 
 +
# TVEnableOverscan=V1
 +
 
 +
and change it to
 +
 
 +
# TVEnableOverscan=V0
 +
 
 +
After changing the settings, reboot.
 +
 
 +
{{note|You might find that the file {{ic|/etc/ati/amdpcsdb}} will be overwritten and revert no matter what you do as user or as root even with log in/log out/reboot, ergo the modification will not stick.
 +
For the amd database file not to be overwritten you have to modify it without the fglrx driver running.
 +
This can be made by rebooting in any "safe mode" that will not use the driver or directly booting into console mode}}
 +
 
 +
'''Workaround:'''
 +
For whatever reason you can find yourself not wanting to touch ATI's config files you can circumvent the problem by forcing the panel's position and resolution:
 +
as user:
 +
 
 +
# aticonfig --set-dispattrib=DISPLAYTYPE,positionX:0
 +
# aticonfig --set-dispattrib=DISPLAYTYPE,positionY:0
 +
# aticonfig --set-dispattrib=DISPLAYTYPE,sizeX:1920
 +
# aticonfig --set-dispattrib=DISPLAYTYPE,sizeY:1080
 +
 
 +
{{ic|DISPLAYTYPE}} will be the name of the monitor you want to change its attributes, for example "dfp9".
 +
To get the name of your {{ic|DISPLAYTYPE}} run the following command:
 +
 +
# xrandr --current
 +
 
 +
Should RandR be not enabled use:
 +
 
 +
# aticonfig --query-monitor
 +
 
 +
Using the display switch or DISPLAY variable set to the appropriate display/screen (:0.1 for example) might be necessary.
 +
 
 +
That will show you which displays are connected and disconnected and its properties
 +
 
 +
This workaround will not persist but it is a quick fix that will show that the panel works just fine and that the above solutions are to be put into place.
 +
 
 +
{{note|{{ic|<nowiki>aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0</nowiki>}} should not be used on newer versions of the driver as it is deprecated and will be soon removed as stated by ATI.}}
 +
 
 +
Try {{ic|<nowiki>aticonfig --help | grep set-pcs-val</nowiki>}} to read ATI's notice
 +
 
 +
=== Dual Screen Setup: general problems with acceleration, OpenGL, compositing, performance ===
 +
Try to disable xinerama and xrandr12. Check out ie. this way:
 +
 
 +
Type those commands:
 +
# aticonfig --initial
 +
# aticonfig --set-pcs-str="DDX,EnableRandR12,FALSE"
 +
Then reboot your system. In {{ic|/etc/X11/xorg.conf}} check that xinerama is disabled, if it is not, disable it and reboot your system.
 +
 
 +
Next run {{ic|amdcccle}} and pick up amdcccle → display manager → multi-display → multidisplay desktop with display(s) 2.
 +
 
 +
Reboot again and set up your display layout whatever you desire.
 +
 
 +
=== Disabling VariBright feature ===
 +
[http://support.hp.com/vn-en/document/c02848104 Vari-Bright] is a feature designed to save power by dynamically adjusting how much power the display panel uses.
 +
Enter the following command to disable VariBright:
 +
# aticonfig --set-pcs-u32=MCIL,PP_UserVariBrightEnable,0
 +
 
 +
=== Hybrid/PowerXpress: turning off discrete GPU ===
 +
When you are using packages with powerXpress support and you are switching to integrated GPU you may notice that discrete GPU is still working, consuming power and making your system's temperature higher.
 +
 
 +
Sometimes ie. when your integrated GPU is intel's one you can use {{ic|vgaswitcheroo}} to turn the discrete GPU off.
 +
Sometimes unfortunately, it is not working.
 +
 
 +
Then you may check out [https://aur.archlinux.org/packages/?O=0&K=acpi_call acpi_call]. MrDeepPurple has prepared the script which he is using to perform 'turn off' task. He is calling script via systemd service while booting and resuming his system.
 +
Here is his script:
 +
#!/bin/sh
 +
libglx=$(/usr/lib/fglrx/switchlibglx query)
 +
modprobe acpi_call
 +
if [ "$libglx" = "intel" ]; then
 +
    echo '\_SB.PCI0.PEG0.PEGP._OFF' > /proc/acpi/call
 +
fi
 +
 
 +
=== Switching from X session to TTYs gives a blank screen/low resolution TTY ===
 +
Workaround for this "feature", which appeared in catalyst 13.2 betas, is to use {{ic|1=vga=}} kernel option, like {{ic|1=vga=792}}.
 +
You can get the list of supported resolutions with the
 +
$ hwinfo --framebuffer
 +
command. Get the one that corresponds to your wanted resolution, and copy-paste it into kernel line of your bootloader, so it could look like ie. {{ic|1=vga=0x03d4}}
 +
 
 +
=== Switching from X session to TTYs gives a black screen with the monitor backlight on ===
 +
Use [[uvesafb]] as your framebuffer driver. Moreover with {{ic|uvesafb}} it is also possible to set whatever resolution for the TTY.
 +
 
 +
=== Switching to TTYs then back to X session gives a black screen with a mouse cursor ===
 +
If you experience this bug, try adding
 +
Option      "XAANoOffscreenPixmaps" "true"
 +
to the 'Device' section of your xorg.conf file.
 +
 
 +
Also, make sure you have a [[Polkit#Authentication agents|polkit authentication agent]] installed and running, as this behavior can happen when a program is asking for a password, but does not have an authentication agent installed to display the password dialog box.
 +
 
 +
=== 30 FPS / Tear-Free / V-Sync bug ===
 +
Bug introduced in Catalyst 13.6 beta, not fixed till now (13.9).
 +
 
 +
After enabling "Tear-Free" functionality every freshly started OpenGL application is lagging, often generates only 30 FPS, it also touches composited desktop.
 +
 
 +
Workaround is pretty simple and was found by M132. Here are the steps, do everything in "AMD Catalyst Control Center" (amdcccle) application:
 +
 
 +
1. Enable Tear-Free, it will set 3D V-Sync option to "Always on".
 +
2. Set 3D V-Sync to "Always Off".
 +
3. Make sure Tear-Free is still on.
 +
4. Restart X / Re-login.
 +
 
 +
It is working well on KDE 4.11.x, but in case of problems M132 suggests: "Try disabling "Detect refresh rate" and specify monitor's refresh rate in the Composite plugin."
 +
 
 +
=== Backlight adjustment does not work ===
 +
If you have a problem with backlight adjustment, you can try the following command:
 +
# aticonfig --set-pcs-u32=MCIL,PP_PhmUseDummyBackEnd,1
 +
Some users reported that this can decrease FPS. To restore defaults, run:
 +
# aticonfig --set-pcs-u32=MCIL,PP_PhmUseDummyBackEnd,0
 +
[http://ati.cchtml.com/show_bug.cgi?id=711 Read more about this bug]
 +
 
 +
=== Chromium glitching when using plasma ===
 +
Add --disable-gpu execute option to the chromium, ie. to /usr/share/applications/chromium.desktop file, like here:
 +
# cat /usr/share/applications/chromium.desktop | grep -i exec
 +
Exec=chromium %U --disable-gpu
 +
 
 +
=== Xorg crashes ===
 +
 
 +
==== Unsupported Xorg Version ====
  
=== Not using fullscreen resolution at 1920x1080 (underscanning) ===
+
When having a supported Linux kernel version but an unsupported Xorg version, you might get this error message and Xorg will crash
  
Using the amdcccle gui you can select the display, go to adjustments, and set Underscan to 0% (aticonfig defaults to 15% underscan).
+
(WW) fglrx: No matching Device section for instance (BusID PCI:0@0:17:0) found
 +
(...)
 +
/usr/bin/Xorg.bin: symbol lookup error: /usr/lib/xorg/modules/drivers/fglrx_drv.so: undefined symbol: GlxInitVisuals2D
 +
xinit: giving up
 +
xinit: unable to connect to X server: Connection refused
 +
xinit: server error
  
Alternatively, you can edit your xorg.conf by adding this line to remove the default underscanning on a per screen basis:
+
For example: fglrx 15.20.3 does not support Xorg 1.17.
  
Option      "DPMS" "true"
+
To solve this, you should downgrade Xorg. A helpful list of steps can be found on [https://gist.github.com/anonymous/9ea8d3774f7afce3a605]

Owners of ATI/AMD video cards have a choice between AMD's proprietary driver (catalystAUR) and the open source driver (ATI for older or AMDGPU for newer cards). This article covers the proprietary driver.

AMD's Linux driver package catalyst was previously named fglrx (FireGL and Radeon X). Only the package name has changed, while the kernel module retains its original fglrx.ko filename. Therefore, any mention of fglrx below is specifically in reference to the kernel module, not the package.

Catalyst packages are no longer offered in the official repositories. In the past, Catalyst has been dropped from official Arch support because of dissatisfaction with the quality and speed of development. After a brief return they were dropped again in April 2013 and they have not returned since.

Compared with the open source driver, Catalyst performs better in both 2D and 3D rendering, also having better power management, but it lacks efficient multi-head support. Supported devices are ATI/AMD Radeon video cards with chipset R600 and newer (Radeon HD 2xxx and newer). See the Xorg decoder ring or this table, to translate model names (X1900, HD4850) to/from chip names (R580, RV770 respectively).

Contents

Installation

There are three ways of installing Catalyst on your system. One way is to use Vi0L0's (Arch's unofficial Catalyst maintainer) repository. This repository contains all the necessary packages. The second method you can use is the AUR; PKGBUILDs offered here are also made by Vi0L0 and are the same he uses to built packages for his repository. Lastly, you can install the driver directly from AMD.

Before choosing the method you prefer, you will have to see which driver you need. Since Catalyst 12.4, AMD has separated its development for Radeon HD 2xxx, 3xxx and 4xxx cards into the legacy Catalyst driver. For Radeon HD 5xxx and newer, there is the regular Catalyst driver. Regardless of the driver you need, you will also need the Catalyst utilities.

Note: After the instructions for every method of installing, you will find general instructions everyone has to perform, regardless of the method you used.

Installing the driver

Installing from the unofficial repository

If you do not fancy building the packages from the AUR, this is the way to go. The repository is maintained by our unofficial Catalyst maintainer, Vi0l0. All packages are signed and are considered safe to use. As you will see later on in this article, Vi0L0 is also responsible for many other packages that will help you get your system working with your ATI graphic cards.

Vi0L0 has three different Catalyst repositories, each having different drivers:

  • catalyst for the regular Catalyst driver needed by Radeon HD 5xxx and up, it contains the latest (stable or beta) Catalyst release.
  • catalyst-stable for the regular Catalyst driver needed by Radeon HD 5xxx and up, with the latest stable driver.
  • catalyst-hd234k for the legacy Catalyst driver needed by Radeon HD 2xxx, 3xxx and 4xxx cards.

To enable one of these, follow the instructions in Unofficial user repositories. Remember to add the chosen repository above all other repositories in pacman.conf.

Note: The catalyst and catalyst-stable repositories share the same URL. To enable catalyst-stable, follow the instructions for enabling catalyst and replace [catalyst] with [catalyst-stable] in pacman.conf. If you need to stick with an old version, there are also some versioned repositories using the same URL (for example catalyst-stable-13.4).
Tip: Because catalyst.wirephire.com will go down if a certain bandwidth limit is exceeded (this happened in the past) or may be too slow at your location, repository mirror is provided by goll at [1] (DE). This mirror however come with no warranty and is not guaranteed to always be operational.

Once you have added some Catalyst repository, update pacman's database and install these packages (see #Tools for more information):

  • catalyst-hook
  • catalyst-utils
  • catalyst-libgl
  • opencl-catalyst - optional, needed for OpenCL support
  • lib32-catalyst-utils - optional, needed for 32-bit OpenGL support on 64-bit systems
  • lib32-catalyst-libgl - optional, needed for 32-bit OpenGL support on 64-bit systems
  • lib32-opencl-catalyst - optional, needed for 32-bit OpenCL support on 64-bit systems
Note: If pacman asks you about removing libgl you can safely do so.
Warning: catalyst package was removed from Vi0L0's repository, its place was taken by catalyst-hook.

Installing from the AUR

The second way to install Catalyst is from the AUR. If you want to build the packages specifically for your computer, this is the way to go. Note that this is also the most tedious way to install Catalyst; it requires the most work and also requires manual updates upon every kernel update.

Warning: If you install the Catalyst package from the AUR, you will have to rebuild Catalyst every time the kernel is updated. Otherwise X will fail to start.

All packages mentioned above in Vi0L0's unofficial repository are also available on the AUR:

The AUR also holds some packages that are not found in any of the repositories. These packages contain the so-called Catalyst-total packages and the beta versions:

The catalyst-totalAUR packages are made to make the lives of AUR users easier. It builds the driver, the kernel utilities and the 32 bit kernel utilities. It also builds the catalyst-hookAUR package, which is described in #Tools.

Configuring the driver

After you have installed the driver via your chosen method, you will have to configure X to work with Catalyst. Also, you will have to make sure the module gets loaded at boot. Also, one should disable kernel mode setting.

Configuring X

To configure X, you will have to create an xorg.conf file. Catalyst provides its own aticonfig tool to create and/or modify this file. It also can configure virtually every aspect of the card for it also accesses the /etc/ati/amdpcsdb file. For a complete list of aticonfig options, run:

# aticonfig --help | less
Warning: Use the --output option before committing to /etc/X11/ as an xorg.conf file will override anything in /etc/X11/xorg.conf.d/
Note: To adhere to the new config location use # aticonfig [...] --output to adapt the Device section to /etc/X11/xorg.conf.d/20-radeon.conf. The drawback is that many aticonfig options rely on an xorg.conf, and will be unavailable.

Now, to configure Catalyst. If you have only one monitor, run this:

# aticonfig --initial

However, if you have two monitors and want to use both of them, you can run the command stated below. Note that this will generate a dual head configuration with the second screen located above the first screen.

# aticonfig --initial=dual-head --screen-layout=above
Note: See #Double Screen (Dual Head / Dual Screen / Xinerama) for more information on setting up dual monitors.

You can compare the generated file to one of the Sample Xorg.conf examples listed on the Xorg page.

Although the current Xorg versions auto-detect most options when started, you may want to specify some in case the defaults change between versions.

Here is an example (with notes) for reference. Entries with # should be required, add entries with ## as needed:

Note: With every Catalyst update you should remove amdpcsdb file in this way: kill X, remove /etc/ati/amdpcsdb, start X and then run amdcccle - otherwise the version of Catalyst may display wrongly in amdcccle.

If you need more information on Catalyst, visit this thread.

Loading the module at boot

We have to blacklist the radeon module to prevent it from auto-loading. To do so, blacklist radeon in /etc/modprobe.d/modprobe.conf. Also, make sure that it is not loaded by any file under /etc/modules-load.d/. For more information, see kernel modules#Blacklisting.

Then we will have to make sure that the fglrx module gets auto-loaded. Either add fglrx on a new line of an existing module file located under /etc/modules-load.d/, or create a new file and add fglrx.

Disable kernel mode setting

Note: Do not do this if you are using powerXpress technology (or hybrid AMD-Intel graphics) because Intel driver needs it.

Disabling kernel mode setting is important, as the Catalyst driver does not take advantage of KMS. If you do not deactivate KMS, your system might freeze when trying to switch to a TTY or even when shutting down via your DE.

To disable kernel mode setting, add nomodeset to your kernel parameters.

Checking operation

Assuming that a reboot to your login was successful, you can check if fglrx is running properly with the following commands:

$ lsmod | grep fglrx

If you get output, it works. Finally, run X manually with $ startx or by using a display manager (see Xorg#Running).

The following command should output your graphic card model name:

$ fglrxinfo

You can then verify that direct rendering is enabled by running the following command in a terminal:

$ glxinfo | grep "direct rendering"

If it says "direct rendering: yes" then you are good to go! If the $ glxinfo command is not found install the mesa-demos package.

Note: You can also use:
$ fgl_glxgears

as the fglrx alternative test to glxgears.

Warning: In recent versions of Xorg, the paths of libs are changed. So, sometimes libGL.so cannot be correctly loaded even if it is installed. Check this if your GL is not working. Please read #Troubleshooting section for details.

Custom kernels

Note: If you are at all uncomfortable or inexperienced with making packages, read up the ABS wiki page first so things go smoothly.

To install catalyst for a custom kernel, you will need to build your own catalyst-$kernel package:

  1. Obtain the PKGBUILD and catalyst.install files from Catalyst.
  2. Editing the PKGBUILD. Two changes need to be made here:
    1. Change pkgname=catalyst to pkgname=catalyst-$kernel_name, where $kernel_name is whatever you want (e.g. custom, mm, themostawesomekernelever).
    2. Change the dependency of linux to $kernel_name.
  3. Build your package and install; run makepkg -i or makepkg followed by # pacman -U pkgname.pkg.tar.gz
Note:
  • If you run multiple kernels, you have to install the catalyst-utilsAUR packages for all kernels. They will not conflict with one another.
  • catalyst-generatorAUR is able to build catalyst-{kernver} packages for you so you do not actually need to perform all those steps manually. For more information, see Tools section.

PowerXpress support

PowerXpress technology allows switching notebooks with dual-graphic capability from integrated graphics (IGP) to discrete graphics either to increase battery life or to achieve better 3D rendering capabilities.

To use such functionality on Arch you will have to:

  • Get and build catalyst-totalAUR / catalyst-testAUR package from the AUR, or
  • Install catalyst-libgl alongside with catalyst-utils packages from the [catalyst] repository.

To perform a switch into Intel's IGP you will also have to install the mesa package and Intel's drivers: xf86-video-intel.

Note: Catalyst sometimes has problems with newest intel drivers. If this is happening please downgrade xf86-video-intel to the previous version found on Arch Linux Archive or maybe even from archive #Xorg repositories alongside with xorg-server package(s).

Now you can switch between the integrated and the discrete GPU, using these commands:

# aticonfig --px-igpu    #for integrated GPU
# aticonfig --px-dgpu    #for discrete GPU

Just remember that fglrx needs /etc/X11/xorg.conf configured for AMD's card with fglrx inside.

You can also use the pxp_switch_catalyst switching script that will perform some additional usefull operations:

  • Switching xorg.conf - it will rename xorg.conf into xorg.conf.cat (if there is fglrx inside) or xorg.conf.oth (if there is intel inside) and then it will create a symlink to xorg.conf, depending on what you chose.
  • Running aticonfig --px-Xgpu.
  • Running switchlibGL.
  • Adding/removing fglrx into/from /etc/modules-load.d/catalyst.conf.

Usage:

# pxp_switch_catalyst amd
# pxp_switch_catalyst intel

If you have got problems when you try to run X on Intel's driver you may try to force "UXA" acceleration. Just make sure you got Option "AccelMethod" "uxa" in xorg.conf:

/etc/X11/xorg.conf
Section "Device"
        Identifier  "Intel Graphics"
        Driver      "intel"
        #Option      "AccelMethod"  "sna"
        Option      "AccelMethod"  "uxa"
        #Option      "AccelMethod"  "xaa"
EndSection

Running two X servers (one using the Intel driver, another one using fglrx) simultaneously

Because fglrx is crash-prone (regarding PowerXpress), it could be a good idea to use the Intel driver in the main X server and have a secondary X server using fglrx when 3D acceleration is needed. However, simply switching to the discrete GPU from the integrated GPU using aticonfig or amdcccle will cause all sorts of weird bugs when starting the second X.

To run two X servers at the same time (each using different drivers), you should firstly set up a fully working X with Catalyst and then move its xorg.conf to a temporary place (for example, /etc/X11/xorg.conf.fglrx. The next time X is started, it will use the Intel driver by default instead of fglrx.

To start a second X server using fglrx, simply move xorg.conf back to the proper place (/etc/X11/xorg.conf) before starting X. This method even allows you to switch between running X sessions. When you are done using fglrx, move xorg.conf somewhere else again.

The only disadvantage of this method is not having 3D acceleration using the Intel driver. 2D acceleration, however, is fully functional. Other than that, this will provide us with a completely stable desktop.

Issues with PowerXpress laptops running in AMD mode (pxp_switch_catalyst amd) with external / secondary monitor

When using a PowerXpress laptop in AMD-only mode (ie, setting the discrete card to render everything) you sometimes run into issues with artifacting/duplicating between displays. This is a known issue, and seems to effect 7xxxM series cards.

The artifacting disappears when you transform one of the monitors by either rotating or scaling. So you can use xrandr to fix this:

xrandr --output HDMI1 --left-of LVDS1 --primary --scale 1x1 --output LVDS1 --scale 1.0001x1.0001

Xorg repositories

Catalyst is notorious for its slow update process. As such, it is common that a new Xorg version is pushed down from upstream that will break compatibility for Catalyst. This means that Catalyst users either have to build Xorg packages on their own, or use a backported repository that only contains the Xorg packages that should be hold back. Vi0L0 has stepped in to fulfil this task and provides several backported repositories.

To enable one of these, follow the instructions in Unofficial user repositories (use the same PGP key as for the catalyst repository). Remember to add the chosen repository above all other repositories in pacman.conf, even above your catalyst repository, should you use one.

Tools

Catalyst-hook

Catalyst-hookAUR is a systemd service that will automatically rebuild the fglrx modules while the system shuts down or reboots, but only if it is necessary (e.g. after an update).

Before using this package make sure that both the base-devel group and the linux-headers package (the one specific to the kernel you use) are installed.

To enable the automatic update, enable the catalyst-hook.service:

# systemctl enable catalyst-hook
# systemctl start catalyst-hook

You can also use this package to build the fglrx module manually. Simply run the catalyst_build_module script after the kernel has been updated:

# catalyst_build_module all

A few more technical details:

The catalyst-hook.service is stopping the systemd "river" and is forcing systemd to wait until catalyst-hook finishes its job.

The catalyst-hook.service is calling the catalyst_build_module check function which checks if fglrx rebuilds are really necessary.

The check function is checking if the fglrx module exists, if it:

  • does not exist, it will build it;
  • does exist, it will compare the two values to be sure that a rebuild is necessary.

These values are md5sums of the /usr/lib/modules/<kernel_version>/build/Module.symvers file (because I, Vi0L0, noticed that this file is unique and different for every kernel's release). The first value is the md5sum of the existing Module.symvers file. The second value is the md5sum of the Module.symvers file which existed in a moment of the fglrx module creation. This value was compiled into the fglrx module by a catalyst_build_module script.

If the values are different, it will compile the new fglrx module.

The check is checking the whole /usr/lib/modules/ directory and building modules for all of the installed kernels if it is necessary. If the build or rebuild is not necessary, the whole process takes only some milliseconds to complete before it gets killed by systemd.

Catalyst-generator

catalyst-generatorAUR is a package that is able to build and install the fglrx module packed into pacman compliant catalyst-${kernver} packages. The basic difference from #Catalyst-hook is that you will have to trigger this command manually, whereas Catalyst-hook will do this automatically at boot when a new kernel got installed.

It creates catalyst-${kernver} packages using makepkg and installs them with pacman. ${kernver} is the kernel version for which each package was built (e.g. catalyst-2.6.35-ARCH package was built for 2.6.35-ARCH kernel).

To build and install catalyst-${kernver} package for a currently booted kernel as an unprivileged user (non-root; safer way), use catalyst_build_module. You will be asked for your root password to proceed to package installation.

A short summary on how to use this package:

  1. As root: catalyst_build_module remove. This will remove all unused catalyst-{kernver} packages.
  2. As unprivileged user: catalyst_build_module ${kernver}, where ${kernver} is the version of the kernel to which you just updated. For example: catalyst_build_module 2.6.36-ARCH. You can also build catalyst-{kernver} for all installed kernels by using catalyst_build_module all.
  3. If you want to remove catalyst-generator, it is best to run this as root before removing catalyst-generator: catalyst_build_module remove_all. This will remove all catalyst-{kernver} packages from the system.

Catalyst-generator is not able to remove all those catalyst-{kernver} packages automatically while being removed because there can not be more than one instance of pacman running. If you forget to run # catalyst_build_module remove_all before using # pacman -R catalyst-generator catalyst-generator will tell you which catalyst-{kernver} packages you will have to remove manually after removing catalyst-generator itself.

Catalyst-generator is most safe and KISS-friendly solution because:

  1. you can use unprivileged user to build the package;
  2. it is building modules in a fakeroot environment;
  3. it is not throwing files here and there, pacman always knows where they are;
  4. all you have to do is to remember to use it
Note: If you see those warnings:
WARNING: Package contains reference to $srcdir
WARNING: '.pkg' is not a valid archive extension.
while building catalyst-{kernver} package, do not be concerned, it is normal.

OpenCL and OpenGL development

Since years AMD is working on tools for OpenCL and OpenGL developement.

Now under the banner of "Heterogeneous Computing" AMD is providing even more of them, fortunately most of their computing tools are available also for Linux.

In the AUR and the [catalyst] repositories you will find packages that represent the most important work from AMD, namely:

APP shortcut stands for Accelerated Parallel Processing.

amdapp-aparapi

AMD's Aparapi is an API for expressing data parallel workloads in Java and a runtime component capable of converting the Java bytecode of compatible workloads into OpenCL so that it can be executed on a variety of GPU devices. If Aparapi can’t execute on the GPU, it will execute in a Java thread pool.

You can find more information about Aparapi here.

amdapp-sdk (formerly known as amdstream)

The AMD APP Software Development Kit (SDK) is a complete development platform created by AMD to allow you to quickly and easily develop applications accelerated by AMD APP technology. The SDK provides samples, documentation and other materials to quickly get you started leveraging accelerated compute using OpenCL, Bolt, or C++ AMP in your C/C++ application.

Since version 2.8 amdapp-sdk is providing aparapiUtil as well as aparapi's samples. A package is available on the [catalyst] repository; it depends on the amdapp-aparapiAUR package. The AUR's package will let you decide whether you want aparapi's additions or not.

Version 2.8 does not provide Profiler functionality, it has been moved to CodeXL.

You can find more information about AMD APP SDK here.

amdapp-codexl

CodeXL is an OpenCL and OpenGL Debugger and Profiler, with a static OpenCL kernel analyzer. It is a GUI application written atop of the well known gdebuggerAUR[broken link: archived in aur-mirror] and is available only for x86_64 systems.

You can find more informations about CodeXL here.

Features

Tear Free Rendering

Presented in Catalyst 11.1, the Tear Free Desktop feature reduces tearing in 2D, 3D and video applications. This likely adds triple-buffering and v-sync. Do note that it requires additional GPU processing.

To enable 'Tear Free Desktop' run amdcccle and go to: Display OptionsTear Free.

Or run:

# aticonfig --set-pcs-u32=DDX,EnableTearFreeDesktop,1

To disable, again use amdcccle or run:

# aticonfig --del-pcs-key=DDX,EnableTearFreeDesktop

Video acceleration

Video Acceleration API (VA API) is an open source software library (libVA) and API specification which provides GPU acceleration for video processing on Linux/UNIX based operating systems. The process works by enabling hardware accelerated video decode at various entry-points (VLD, IDCT, Motion Compensation, deblocking) for common encoding standards (MPEG-2, MPEG-4 ASP/H.263, MPEG-4 AVC/H.264, and VC-1/WMV3).

VA-API gained a proprietary backend (in November 2009) called xvba-videoAUR[broken link: archived in aur-mirror], that allows VA-API programmed applications to take advantage of AMD Radeons UVD2 chipsets via the XvBA (X-Video Bitstream Acceleration API designed by AMD) library.

Note: No need to install the xvba-videoAUR[broken link: archived in aur-mirror] package when using catalyst-test or catalyst-total, because a symlink is being used instead.

XvBA support and xvba-video is still under development, however it is working very well in most cases. Build (or install from Vi0L0's repo) the proprietary xvba-videoAUR[broken link: archived in aur-mirror] package, or if you have problems with that version, install libva-xvba-driverAUR; and also install mplayer-vaapiAUR and libva. Then just set your video player to use vaapi:gl as video output:

$ mplayer -vo vaapi:gl movie.avi

These options can be added to your mplayer configuration file, see MPlayer.

For smplayer:

Options → Preferences → General → Video (tab) → Output driver: User Defined : vaapi:gl
Options → Preferences → General → Video (tab) → Double buffering on
Options → Preferences → General → General → Screenshots → Turn screenshots off
Options → Preferences → Performance → Threads for decoding: 1 (to turn off -lavdopts parameter)
Note: If Tear Free Desktop is enabled it is better to use:
Options → Preferences → General → Video (tab) → Output driver: vaapi

If Video Output vaapi:gl is not working - please check:

vaapi, vaapi:gl2 or simply xv(0 - AMD Radeon AVIVO Video).

For VLC:

Tools → Preferences → Input & Codecs → Use GPU accelerated decoding

It might help to enable v-sync in amdcccle:

3D → More Settings → Wait for vertical refresh = Always On
Note: If you are using Compiz/KWin, the only way to avoid video flickering is to watch videos in full-screen and only when Unredirect Fullscreen is off. In compiz you need to set Redirected Direct Rendering in General Options of ccsm. If it is still flickering, try to disable this option in CCSM. It is off by default in KWin, but if you see flickering try to turn "Suspend desktop effects for fullscreen windows" on or off in System SettingsDesktop EffectsAdvanced.

GPU/Mem frequency, Temperature, Fan speed, Overclocking utilities

You can get the GPU/Mem clocks with: $ aticonfig --od-getclocks.

You can get the fan speed with: $ aticonfig --pplib-cmd "get fanspeed 0"

You can get the temperature with: $ aticonfig --odgt

To set the fanspeed with: $ aticonfig --pplib-cmd "set fanspeed 0 50" Query Index: 50, Speed in percent

To overclock and/or underclock it is easier to use a GUI, like ATi Overclocking Utility, which is very simple and requires qt to work. It might be out of date/old, but you can get it here.

Another, more complex utility to perform such operations is AMDOverdriveCtrl. Its homepage is here and you can build amdoverdrivectrlAUR from the AUR or from Vi0L0's unofficial repositories.

Double Screen (Dual Head / Dual Screen / Xinerama)

Introduction

Warning: you should know that there is not one specific solution because each setup differs and needs its own configuration. That is why you will have to adapt the steps below to your own needs. It is possible that you have to try more than once. Therefore, you should save your working /etc/X11/xorg.conf before you start modifying and be able to recover from a command-line environment.
  • In this chapter, we will describe the installation of two different-sized screens on only one graphics card with two different output ports (DVI + HDMI) using a "BIG Desktop" configuration.
  • The Xinerama solution has some inconveniences, especially because it is not compatible with XrandR. For that very reason, you should not use this solution, because XrandR is a must for our later configuration.
  • The Dual Head solution would allow you to have 2 different sessions (one for each screen). It could be what you want, but you will not be able to move windows from one screen to another. If you have only one screen, you will have to define the mouse inside your Xorg session for each of the two sessions inside the Server Layout section.

ATI Documentation

ATI Catalyst Control Center

The GUI tool shipped by ATI is very useful and we will try to use it as much as we can. To launch it, open a terminal and use the following command:

$ {kdesu/gksu} amdcccle
Warning: Do not use sudo directly with a GUI. Sudo gives you admin rights with user account information. Instead, use gksu (GNOME) or kdesu (KDE).

Installation

Before we start, make sure that your hardware is plugged in correctly, that power is on and that you know your hardware characteristics (screen dimensions, sizes, refreshment rates, etc.) Normally, both screens are recognized during boot time but not necessarily identified properly, especially if you are not using any Xorg base configuration file (/etc/X11/xorg.conf) but relying on the hot-plugging feature.

The first step is to make sure that you screens will be recognized by your DE and by X. For this, you need to generate a basic Xorg configuration file for your two screens:

# aticonfig --initial --desktop-setup=horizontal --overlay-on=1

or

# aticonfig --initial=dual-head --screen-layout=left
Note: overlay is important because it allows you to have 1 pixel (or more) shared between the 2 screens.
Tip: For the other possible and available options, do not hesitate to type aticonfig --help inside a terminal to display all available command lines.

Now you should have a basic Xorg configuration file that you can edit to add your screen resolutions. It is important to use the precise resolution, especially if you have screens of different sizes. These resolutions have to be added in the "Screen" section:

SubSection "Display"
    Depth     24
    Modes     "X-resolution screen 1xY-resolution screen 1" "Xresolution screen 2xY-resolution screen 2"
EndSubSection

From now on, instead of editing the xorg.conf file manually, let us use the ATI GUI tool. Restart X to be sure that your two screens are properly supported and that the resolutions are properly recognized (Screens must be independent, not mirrored).

Configuration

Now you will only have to launch the ATI control center with root privileges, go to the display menu and choose how you would like to set your configuration (small arrow of the drop down menu). A last restart of X and you should be done!

Before you restart X, do not hesitate to verify your new xorg.conf file. At this stage, inside the "Display" sub-section of the "Screen" section, you should see a "Virtual" command line, of which the resolution should be the sum of both screens. The "Server Layout" section says all the rest.

Uninstallation

If for any reason this driver is not working for you or if you simply want to try out the open source driver, remove the catalyst and catalyst-utils packages. Also you should remove catalyst-generatorAUR, catalyst-hookAUR and lib32-catalyst-utilsAUR packages if they have been installed on your system.

Warning:
  • You may need to use # pacman -Rdd to remove catalyst-utilsAUR (and/or lib32-catalyst-utilsAUR) because that package contains gl related files and many of your installed packages depend on them. These dependencies will be satisfied again when you install xf86-video-ati.
  • You may need to remove /etc/profile.d/ati-flgrx.sh and /etc/profile.d/lib32-catalyst (if it exists on your system), otherwise r600_dri.so will fail to load and you would not have 3D support.
Note: You should remove unofficial repositories from your /etc/pacman.conf and run # pacman -Syu, because those repositories include out-dated Xorg packages to allow use of catalyst and the xf86-video-ati package needs up-to-date Xorg packages from the Official repositories.

Also follow these steps:

  • If you have the /etc/modprobe.d/blacklist-radeon.conf file remove it or comment the line blacklist radeon in that file.
  • If you have a file in /etc/modules-load.d to load the fglrx module on boot, remove it or comment the line containing fglrx.
  • Make sure to remove or backup /etc/X11/xorg.conf.
  • If you have installed the catalyst-hookAUR package, make sure to disable the systemd service.
  • If you used the nomodeset option in your kernel parameters and plan to use KMS, remove it.
  • Reboot before installing another driver.

Troubleshooting

If you can still boot to command-line, then the problem probably lies in /etc/X11/xorg.conf

You can parse the whole /var/log/Xorg.0.log or, for clues:

$ grep '(EE)' /var/log/Xorg.0.log
$ grep '(WW)' /var/log/Xorg.0.log

If you are still confused about what is going on, search the forums first. Then post a message in the thread specific to ATI/AMD. Provide the information from xorg.conf and both commands mentioned above.

Failed to start atieventsd.service

Install acpid from the official repositories. Start and enable the acpid service.

If the service still fails to start, edit /usr/lib/systemd/system/atieventsd.service and change acpid.socket to acpid.service.

Failed to open fglrx_dri.so

Create a symlink from /usr/lib/xorg/modules/dri/fglrx_dri.so to /usr/X11R6/lib64/modules/dri/fglrx_dri.so (or other requested path)

# mkdir -p /usr/X11R6/lib64/modules/dri
# ln -s /usr/lib/xorg/modules/dri/fglrx_dri.so /usr/X11R6/lib64/modules/dri/fglrx_dri.so

GDM fails to start

Downgrade the xorg-server package or try to use another display manager like LightDM.

3D Wine applications freeze

If you use a 3D Wine application and it hangs, you have to disable TLS. To do this, either use aticonfig or edit /etc/X11/xorg.conf. To use aticonfig:

# aticonfig --tls=off

Or, to edit /etc/X11/xorg.conf; first open the file in an editor as root and then add Option "UseFastTLS" "off" to the Device section of this file.

After applying either of the solutions, restart X for it to take effect.

Problems with video colours

You may still use vaapi:gl to avoid video flickering, but without video acceleration:

  • Run mplayer without -vo vaapi switch.
  • Run smplayer remove -vo vaapi from Options → Preferences → Advanced → Options for MPlayer → Options: -vo vaapi

Plus for smplayer you may now safely turn screenshots on.

KWin and composite

You may use XRender if the rendering with OpenGL is slow. However, XRender might also be slower than OpenGL depending on your card. XRender also solves artefact issues in some cases, for instance when resizing Konsole.

Black screen with complete lockups and/or hangs after reboot or startx

Ensure you have added the nomodeset option to the kernel options line in your bootloader (see #Disable kernel mode setting). Make sure that Catalyst is compatible with your installed Xorg version and used Linux kernel version.

If you are using the legacy driver (catalyst-hd234k) and get a black screen, try downgrading xorg-server to 1.12 by using the #xorg112 repository.

Faulty ACPI hardware calls

It is possible that fglrx does not cooperate well with the system's ACPI hardware calls, so it auto-disables itself and there is no screen output.

If so, try to run this:

$ aticonfig --acpi-services=off

KDM disappears after logout

If you are running Catalyst proprietary driver and you get a console (tty1) instead of the expected KDM greeting when you log out, you must instruct KDM to restart the X server after each logout. Uncomment the following line under the section titled [X-:*-Core]

/usr/share/config/kdm/kdmrc
TerminateServer=True

KDM should now appear when you log out of KDE.

Direct Rendering does not work

This problem may occur when using the proprietary Catalyst driver.

Warning: This error would also appear if you have not rebooted your system after the installation or upgrade of catalyst. The system needs to load the fglrx.ko module in order to make the driver work.

If you have problem with direct rendering, run:

$ LIBGL_DEBUG=verbose glxinfo > /dev/null

at the command prompt. At the very start of the output, it will usually give you a nice error message saying why you do not have direct rendering.

Common errors and their solutions, are:

libGL error: XF86DRIQueryDirectRenderingCapable returned false
  • Ensure that you are loading the correct agp modules for your AGP chipset before you load the fglrx kernel module. To determine which agp modules you will need, run # hwdetect --show-agp. Then open your /etc/modules-load.d/fglrx.conf and add the agp module on a line before the fglrx line.
libGL error: failed to open DRM: Operation not permitted

  • Something has not been installed correctly. If the paths in the error message are /usr/X11R6/lib/modules/dri/fglrx_dri.so, then ensure you have logged completely out of your system, then back in. If you are using a graphical login manager (gdm, kdm, xdm), ensure that /etc/profile is sourced every time you log in. This is usually accomplished by adding source /etc/profile into ~/.xsession or ~/.xinitrc, but this may vary between login managers.
  • If the paths above in your error message are /usr/lib/xorg/modules/dri/fglrx_dri.so, then something has not been correctly installed. Try reinstalling the catalystAUR package.

Errors such as:

fglrx: libGL version undetermined - OpenGL module is using glapi fallback

could be caused by having multiple versions of libGL.so on your system. The command below should return the following output:

$ locate libGL.s
/usr/lib/libGL.so
/usr/lib/libGL.so.1
/usr/lib/libGL.so.1.2

These are the only three libGL.so files you should have on your system. If you have any more (e.g. /usr/X11R6/lib/libGL.so.1.2), then remove them. This should fix your problem.

You might not get any error to indicate that this is a problem. If you are using X11R7, make sure you do not have these files on your system:

/usr/X11R6/lib/libGL.so.1.2
/usr/X11R6/lib/libGL.so.1

Hibernate/Sleep issues

Video fails to resume from suspend2ram

ATI's proprietary Catalyst driver cannot resume from suspend if the framebuffer is enabled. To disable the framebuffer, add vga=0 to your kernel kernel parameters.

To see where you need to add this with other bootloaders, see #Disable kernel mode setting.

System freezes/Hard locks

  • The radeonfb framebuffer drivers have been known in the past to cause problems of this nature. If your kernel has radeonfb support compiled in, you may want to try a different kernel and see if this helps.
  • If you experience system freezes when exiting your DE (shut down, suspend, switching to tty etc.) you probably forgot to deactivate KMS. (See #Disable kernel mode setting)

Hardware conflicts

Radeon cards used in conjunction with some versions of the nForce3 chipset (e.g. nForce 3 250Gb) will not have 3D acceleration. Currently the cause of this issue is unknown, but some sources indicate that it may be possible to get acceleration with this combination of hardware by booting Windows with the drivers from nVIDIA and then rebooting the system. This can be verified by getting output something similar to this (using an nForce3-based system):

$ dmesg | grep agp
agpgart: Detected AGP bridge 0
agpgart: Setting up Nforce3 AGP.
agpgart: aperture base > 4G

and also if issuing the following command gets you the following output:

$ tail -n 100 /var/log/Xorg.0.log | grep agp
(EE) fglrx(0): [agp] unable to acquire AGP, error "xf86_ENODEV"

you have this bug.

Some sources indicate that in some situations, downgrading the motherboard BIOS may help, but this cannot be verified in all cases. Also, a bad BIOS downgrade can render your hardware useless, so beware.

See this bugreport for more information and a potential fix.

Temporary hangs when playing video

This problem may occur when using the proprietary Catalyst.

If you experience temporary hangs lasting from a few seconds to several minutes occuring randomly during playback with mplayer, check the system logs for output like:

Adding the nopat and/or nomodeset kernel parameters should work.

"aticonfig: No supported adapters detected"

If you get the following:

# aticonfig --initial
aticonfig: No supported adapters detected

It may still be possible to get Catalyst working by manually setting the device in your your etc/X11/xorg.conf file or by copying an older working /etc/ati/control file (preferred - this also fixes the watermark issue).

To get an older control file, download a previous version of fglrx from AMD and run it with --extract driver parameter. You will find the control file in driver/common/etc/ati/control. Copy the extracted file over the system file and restart Xorg. You can try different versions of the file.

To set your model in xorg.conf, edit the device section of /etc/X11/xorg.conf to:

/etc/X11/xorg.conf
Section "Device"
        Identifier "ATI radeon ****"
        Driver     "fglrx"
EndSection

Where **** should be replaced with your device's marketing number (e.g. 6870 for the HD 6870 and 6310 for the E-350 APU).

Xorg will start and it is possible to use amdcccle instead of aticonfig. There will be an "AMD Unsupported hardware" watermark.

You can remove this watermark using the following script:

#!/bin/sh
DRIVER=/usr/lib/xorg/modules/drivers/fglrx_drv.so
for x in $(objdump -d $DRIVER|awk '/call/&&/EnableLogo/{print "\\x"$2"\\x"$3"\\x"$4"\\x"$5"\\x"$6}'); do
   sed -i "s/$x/\x90\x90\x90\x90\x90/g" $DRIVER
done

and then reboot your machine.

WebGL support in Chromium

Google has blacklisted Linux's Catalyst driver from supporting webGL in their Chromium/Chrome browsers. See Chromium#WebGL for details.

Lag/freezes when watching flash videos via Adobe's flashplugin

Edit:

/etc/adobe/mms.cfg
#EnableLinuxHWVideoDecode=1
OverrideGPUValidation=true

If you are using KDE make sure that "Suspend desktop effects for fullscreen windows" is unchecked under System SettingsDesktop EffectsAdvanced.

Lag/slow windows movement in GNOME3

You can try this solution, it has been reported to work for many people.

Add this line into ~/.profile or into /etc/profile:

export CLUTTER_VBLANK=none

Restart X server or reboot your system.

Not using full screen resolution at 1920x1080 (underscanning, black borders around the screen)

This usually happens when you use a HDMI connection to connect your monitor/TV to your computer.

Seemed to be a feature by AMD/ATI to work with all HDTVs that could be adjusted via the amdccle.

Using the amdcccle GUI you can select the affected display, go to adjustments, and set underscan to 0% (aticonfig defaults to 15% underscan). It is possible as well that the underscan slider will not show under the display's adjustments, as sometimes in (at least) version 14.10.

The problem is that the settings will not persist after restarting X server or rebooting or wake up or might even revert after changing TTYs.

For the changes to become permanent, you will need to adjust the underscan settings manually using "aticonfig" via console (as root) or manually edit the file /etc/ati/amdpcsdb (as root)

using aticonfig method:

# aticonfig --set-pcs-u32=MCIL,DigitalHDTVDefaultUnderscan,0

After changing the settings, reboot.

For newer version (for example, 12.11), if Catalyst control center repeatedly fails to save the overscan setting you can also try:

# aticonfig --set-pcs-u32=MCIL,TVEnableOverscan,0

Manually editing /etc/ati/amdpcsdb method:

Add the following line anywhere under the following header [AMDPCSROOT/SYSTEM/MCIL]

# DigitalHDTVDefaultUnderscan=V0

For newer version (for example, 12.11), if Catalyst control center repeatedly fails to save the overscan setting you can also try: locate under [AMDPCSROOT/SYSTEM/MCIL] the following line

# TVEnableOverscan=V1

and change it to

# TVEnableOverscan=V0

After changing the settings, reboot.

Note: You might find that the file /etc/ati/amdpcsdb will be overwritten and revert no matter what you do as user or as root even with log in/log out/reboot, ergo the modification will not stick.

For the amd database file not to be overwritten you have to modify it without the fglrx driver running.

This can be made by rebooting in any "safe mode" that will not use the driver or directly booting into console mode

Workaround: For whatever reason you can find yourself not wanting to touch ATI's config files you can circumvent the problem by forcing the panel's position and resolution: as user:

# aticonfig --set-dispattrib=DISPLAYTYPE,positionX:0
# aticonfig --set-dispattrib=DISPLAYTYPE,positionY:0
# aticonfig --set-dispattrib=DISPLAYTYPE,sizeX:1920
# aticonfig --set-dispattrib=DISPLAYTYPE,sizeY:1080

DISPLAYTYPE will be the name of the monitor you want to change its attributes, for example "dfp9". To get the name of your DISPLAYTYPE run the following command:

# xrandr --current

Should RandR be not enabled use:

# aticonfig --query-monitor

Using the display switch or DISPLAY variable set to the appropriate display/screen (:0.1 for example) might be necessary.

That will show you which displays are connected and disconnected and its properties

This workaround will not persist but it is a quick fix that will show that the panel works just fine and that the above solutions are to be put into place.

Note: aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0 should not be used on newer versions of the driver as it is deprecated and will be soon removed as stated by ATI.

Try aticonfig --help | grep set-pcs-val to read ATI's notice

Dual Screen Setup: general problems with acceleration, OpenGL, compositing, performance

Try to disable xinerama and xrandr12. Check out ie. this way:

Type those commands:

# aticonfig --initial
# aticonfig --set-pcs-str="DDX,EnableRandR12,FALSE"

Then reboot your system. In /etc/X11/xorg.conf check that xinerama is disabled, if it is not, disable it and reboot your system.

Next run amdcccle and pick up amdcccle → display manager → multi-display → multidisplay desktop with display(s) 2.

Reboot again and set up your display layout whatever you desire.

Disabling VariBright feature

Vari-Bright is a feature designed to save power by dynamically adjusting how much power the display panel uses. Enter the following command to disable VariBright:

# aticonfig --set-pcs-u32=MCIL,PP_UserVariBrightEnable,0

Hybrid/PowerXpress: turning off discrete GPU

When you are using packages with powerXpress support and you are switching to integrated GPU you may notice that discrete GPU is still working, consuming power and making your system's temperature higher.

Sometimes ie. when your integrated GPU is intel's one you can use vgaswitcheroo to turn the discrete GPU off. Sometimes unfortunately, it is not working.

Then you may check out acpi_call. MrDeepPurple has prepared the script which he is using to perform 'turn off' task. He is calling script via systemd service while booting and resuming his system. Here is his script:

#!/bin/sh
libglx=$(/usr/lib/fglrx/switchlibglx query)
modprobe acpi_call
if [ "$libglx" = "intel" ]; then
    echo '\_SB.PCI0.PEG0.PEGP._OFF' > /proc/acpi/call
fi

Switching from X session to TTYs gives a blank screen/low resolution TTY

Workaround for this "feature", which appeared in catalyst 13.2 betas, is to use vga= kernel option, like vga=792. You can get the list of supported resolutions with the

$ hwinfo --framebuffer

command. Get the one that corresponds to your wanted resolution, and copy-paste it into kernel line of your bootloader, so it could look like ie. vga=0x03d4

Switching from X session to TTYs gives a black screen with the monitor backlight on

Use uvesafb as your framebuffer driver. Moreover with uvesafb it is also possible to set whatever resolution for the TTY.

Switching to TTYs then back to X session gives a black screen with a mouse cursor

If you experience this bug, try adding

Option      "XAANoOffscreenPixmaps" "true"

to the 'Device' section of your xorg.conf file.

Also, make sure you have a polkit authentication agent installed and running, as this behavior can happen when a program is asking for a password, but does not have an authentication agent installed to display the password dialog box.

30 FPS / Tear-Free / V-Sync bug

Bug introduced in Catalyst 13.6 beta, not fixed till now (13.9).

After enabling "Tear-Free" functionality every freshly started OpenGL application is lagging, often generates only 30 FPS, it also touches composited desktop.

Workaround is pretty simple and was found by M132. Here are the steps, do everything in "AMD Catalyst Control Center" (amdcccle) application:

1. Enable Tear-Free, it will set 3D V-Sync option to "Always on".
2. Set 3D V-Sync to "Always Off".
3. Make sure Tear-Free is still on.
4. Restart X / Re-login.

It is working well on KDE 4.11.x, but in case of problems M132 suggests: "Try disabling "Detect refresh rate" and specify monitor's refresh rate in the Composite plugin."

Backlight adjustment does not work

If you have a problem with backlight adjustment, you can try the following command:

# aticonfig --set-pcs-u32=MCIL,PP_PhmUseDummyBackEnd,1

Some users reported that this can decrease FPS. To restore defaults, run:

# aticonfig --set-pcs-u32=MCIL,PP_PhmUseDummyBackEnd,0

Xorg crashes

Unsupported Xorg Version

When having a supported Linux kernel version but an unsupported Xorg version, you might get this error message and Xorg will crash

(WW) fglrx: No matching Device section for instance (BusID PCI:0@0:17:0) found
(...)
/usr/bin/Xorg.bin: symbol lookup error: /usr/lib/xorg/modules/drivers/fglrx_drv.so: undefined symbol: GlxInitVisuals2D
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error

For example: fglrx 15.20.3 does not support Xorg 1.17.

To solve this, you should downgrade Xorg. A helpful list of steps can be found on [2]
