Debian

= Installation =

The open-source ati/radeon driver should already be installed and used as the default. This guide focuses on installing the proprietary ATI driver (fglrx/Catalyst).

Before Starting
If you have previously attempted installing Catalyst, remove any leftover files by following the Removing the Driver section.

Which cards are no longer supported by ATI Catalyst? The ATI Radeon 9500-9800, Xpress200-1250, 690G, 740G, X300-X2500 (including Mobility RadeonHD 2300, since it is really a DirectX 9 part). See the complete list here. If your card is on that list, you are limited to open-source drivers on Debian Squeeze/6.0 (and later). If you really need the proprietary Catalyst/fglrx driver, you will have to use Debian Lenny/5.0.x and install Catalyst 9-3.
 * PLEASE READ FIRST!

Installing from Debian Repository
Debian considers fglrx non-free software, so it is located in the non-free repository. If you do not have non-free enabled, you can do so like this: http://serverfault.com/questions/240920/how-do-i-enable-non-free-packages-on-debian

$ sudo apt-get remove --purge xserver-xorg-video-radeon $ sudo apt-get install fglrx-driver fglrx-control fglrx-glx fglrx-atieventsd fglrx-modules-dkms

If you are using 64-bit Debian, install the 32-bit fglrx libraries for use with 32-bit programs.

$ sudo apt-get install fglrx-glx-ia32

Installing Manually
This method uses the latest Catalyst driver downloaded from AMD/ATI's site.

Prerequisite Packages
Install the prerequisite packages (names are based on Debian sid, older Debians may be different): $ sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 If you are using the x86_64 architecture (64 bit), be sure to install "ia32-libs" before proceeding! $ sudo apt-get install ia32-libs

Download the latest Catalyst package.
This package contains both the 32-bit and 64-bit driver. $ cd ~/; mkdir catalyst; cd catalyst/ $ wget http://www2.ati.com/drivers/linux/ati-driver-installer- -x86.x86_64.run $ chmod +x ati-driver-installer--x86.x86_64.run

Create .deb packages.
will be one of the following: Debian/sid Debian/unstable Debian/etch Debian/stable Debian/lenny Debian/testing  Debian/experimental $ sudo ./ati-driver-installer--x86.x86_64.run --buildpkg

Install .debs.
$ sudo dpkg -i fglrx*.deb

Generate a new /etc/X11/xorg.conf file
Unfortunately, there is no sure way to generate the ATI version of the Xorg.conf file. It is entirely dependent on your configuration. The following subsections will attempt to address possible (and tested) variations for their respective configurations.

Generic Config
This will work for most people: $ sudo aticonfig --initial -f

Minimal Config
A very basic /etc/X11/xorg.conf file might be what you need if you have a new card that's not fully supported by aticonfig. Here follows the entirety of a minimal xorg.conf file for the Radeon 6870:

Section "Device" Identifier "ATI radeon 6870" Driver "fglrx" EndSection

X2/Dual GPU Cards
If you have an X2 card (e.g. 4870X2 or 5970), use... !!Do not use for two separate cards in crossfire!! $ sudo aticonfig --initial -f --adapter = all

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

Force use of the new xorg.conf (if necessary)
Some people find that changes to xorg.conf don't get used by the driver. To force the ATI driver to adopt changes made to xorg.conf, use the following command:

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

Test your installation
NOTE: if you don't reboot first, fglrxinfo gives an error message. Reboot the computer and type $ fglrxinfo into the terminal. If the vendor string contains ATI, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 11-4 and a RadeonHD 4250 returns: display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 4200 Series (This line may be different depending on what graphics card you are using.) OpenGL version string: 3.3.10665 Compatibility Profile Context (This line may be different depending on what graphics card and Catalyst version you are using.) Now, try: $ fgl_glxgears If you experience issues or a hang, you may need to disable fast TLS. $ sudo aticonfig --tls=0

= Hardware Video Decode Acceleration (EXPERIMENTAL) = 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

Debian wheezy/7.0 and Later
$ sudo apt-get install xvba-va-driver

=Updating Catalyst/fglrx=

DO NOT try to install a new version over an old one. Follow the Removing the Driver section below to remove your existing driver.

=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* xorg-driver-fglrx

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 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
