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.
This will work for most people:
$ sudo amdconfig --initial -f
If you are using dual head, that is to say, two _different_ desktops on two monitors, do this:
$ sudo amdconfig --initial=dual-head -f
Most people with two or more monitors will want instead one large desktop; to do this you may have to specify your monitors individually in the xorg.conf file and tell the driver to use a larger desktop size (big enough to contain both monitors) then use xrandr to configure the monitor arrangement.
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 amdconfig. 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 amdconfig --initial -f --adapter=all
A post at http://phoronix.com/forums/showthread.php?t=18553 suggested to do the following to use a dual monitor display (also known as "Big Desktop"):
$ sudo amdconfig --initial -f $ sudo amdconfig --set-pcs-str="DDX,EnableRandR12,FALSE"
However the information is dated 2009 and now believed to be obsolete.
For multiple monitors, instead try specifying all monitors in your xorg.conf file. Use the following as a starting point:
Section "ServerLayout" Identifier "amdconfig Layout" Screen 0 "amdconfig-Screen-0" 0 0 EndSection Section "Module" EndSection Section "Monitor" Identifier "0-DFP6" Option "DPMS" "true" Option "PreferredMode" "1920x1080" EndSection Section "Monitor" Identifier "0-CRT1" Option "DPMS" "true" Option "PreferredMode" "1280x1024" EndSection Section "Device" Identifier "amdconfig-Device-0" Driver "fglrx" BusID "PCI:1:0:0" Option "Monitor-DFP6" "0-DFP6" Option "Monitor-CRT1" "0-CRT1" EndSection Section "Screen" Identifier "amdconfig-Screen-0" Device "amdconfig-Device-0" Monitor "0-DFP6" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 # Big Desktop: 1920+1280=3200, max(1080,1024)=1080 Virtual 3200 1080 EndSubSection EndSection
After starting X successfully, use xrandr to check the maximum screen size is large enough for your combined desktop:
$ xrandr Screen 0: minimum 320 x 200, current 3200 x 1080, maximum 3200 x 1080
And positioning of connected monitors:
DFP1 disconnected (normal left inverted right x axis y axis) DFP2 disconnected (normal left inverted right x axis y axis) DFP3 disconnected (normal left inverted right x axis y axis) DFP4 disconnected (normal left inverted right x axis y axis) DFP5 disconnected (normal left inverted right x axis y axis) DFP6 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 531mm x 299mm [modes elided] CRT1 connected 1280x1024+1920+56 (normal left inverted right x axis y axis) 338mm x 270mm
Use xrandr (or in KDE, krandrtray) to reposition your monitors within your screen.
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 amdconfig --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
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.)
If you experience issues or a hang, you may need to disable fast TLS.
$ sudo amdconfig --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
DO NOT try to install a new version over an old one. Follow the Removing the Driver section below to remove your existing driver.
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
Catalyst 11.9 and Debian Squeeze x86_64 (October 2011)
Version 11.9 will not install on Debian Squeeze with Kernel >= 3.1. To fix and install proceed as follows. First uninstall all versions of fglrx you can find, see above. (!!)
Download the driver and extract it thusly:
$ sudo ./ati-driver-installer-11-9-x86.x86_64.run --keep
Enter the newly created directory (will be named fglrx-install.XXXXXX). Use a hexeditor to find bytes starting at A6B0 with the values e8 53 90 ff ff and replace them with 90 90 90 90 90. This replaces a faulty free-op with 5 no-ops and fixes the exception thrown by "setup.data/bin/x86_64/setup". Read up on this at http://disbauxes.upc.es/?p=2964 .
Now the kernel-build-environment for the 3.1 kernel is currently missing in the repositories. To get around that type:
$ sudo aptitude install linux-source-3.1.0-rc7 $ cd /usr/src;tar -xjf linux-source-3.1.0-rc7;ln -s linux-source-3.1.0-rc7 linux;cd linux;
You may need to append an "-amd64" (or similar) to the localversion of the source to have its version-string match the one of the running kernel. To do so open .config in the current dir with an editor and search for "LOCALVERSION", set that var to "-amd64" or similar. Configure the kernel using
$ sudo make oldconfig
and build it using
$ make-kpkg --initrd --append-to-version="-myversion" kernel_image kernel_headers modules_image
You may not need to rebuild the whole kernel, installing its headers may be enough, but i wanted a fresh kernel with a few custom options. Install your kernel (or just the headers) from the .deb-files that were created by make-kpkg in the directory above.
After this return to the directory where you extracted the driver to and type:
$ sudo ./amd-installer.sh 8.892 --install --force
To load the driver type:
$ sudo modprobe fglrx
Debian Squeeze x86_64 and AMD A Series (June 2012)
First install Kernel 3.2 from squeeze-backports. Add backports to your sources.list Add this line
deb http://backports.debian.org/debian-backports squeeze-backports main contrib non-free
to your sources.list (or add a new file to /etc/apt/sources.list.d/)
$ sudo apt-get update $ sudo apt-get -t squeeze-backports install linux-image-3.2.0-0.bpo.2-amd64
$ sudo reboot
$ sudo apt-get remove --purge xserver-xorg-video-radeon $ sudo apt-get -t squeeze-backports 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 -t squeeze-backports install fglrx-glx-ia32
