The latest fglrx driver supports Radeon 9500+ and the X-series cards up to X1900.
Pre-Installation Checks
Enable "restricted" Repository
Make sure the restricted repository is enabled in /etc/apt/sources.list or this guide will not work!
Disable Composite Extension
In Ubuntu Edgy the Composite extension is enabled by default, however, fglrx does not yet support Composite with DRI. In order to disable Composite you have to edit the xorg.conf file:
sudo gedit /etc/X11/xorg.conf
and add these lines at the end of the file:
File: /etc/X11/xorg.conf |
Section "Extensions" Option "Composite" "Disable" EndSection |
- Note: Xubuntu does not have gedit. The default text editor in Xubuntu is called mousepad.
- Note: Kubuntu does not have gedit. The default text editor in Kubuntu is called Kate. Another option is to use nano.
Installation
Install the Driver
sudo apt-get update sudo apt-get install linux-restricted-modules-$(uname -r) #Okay if it is already installed sudo apt-get install xorg-driver-fglrx sudo depmod -a
Configure the Driver
sudo aticonfig --initial sudo aticonfig --overlay-type=Xv
- Note: An alternative to the aticonfig --initial command is to edit /etc/X11/xorg.conf and replace the string "ati" with "fglrx" in the "Device" section. This way you won't lose your old "Screen" and "Monitor" settings. Afterwards you can use aticonfig for setting overlay etc.
sudo aticonfig --overlay-type=Xv
Finish the Installation
Now Reboot your system:
sudo shutdown -r now
- Note: An alternative to rebooting is to restart the X Server by pressing your CTRL+ALT+BACKSPACE keys. You must remove any old kernel modules such as "drm" "radeon" or "fglrx".
Post-Installation Checks
Verifying
Run the following command to check its output to insure the fglrx driver is installed properly:
$fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: RADEON 9600 Generic OpenGL version string: 2.0.6011 (8.28.8)
Ubuntu-specific Issues
Revert to Xorg driver
If (for any reason) the fglrx install fails, you can revert to the Xorg driver by executing
sudo dpkg-reconfigure xserver-xorg
and selecting the "ati" driver, or simply restoring the previous /etc/X11/xorg.conf file, if you made a backup.
You also need to remove the xorg-driver-fglrx or your manually installed drivers to get the 3D acceleration back, since it is provided by file /usr/lib/libGL.so.1.2 which belongs to libgl1-mesa package and which is moved to backup and replaced at the installation of xorg-driver-fglrx (or the manually built) package. In case the removal of the fglrx drivers fails to restore the file from libgl1-mesa, you have to reinstall the package by running:
sudo apt-get install --reinstall libgl1-mesa
