In openSUSE 11.0, AiGLX with Compsite is enabled by default. So, if you prefer to use AIGLX rendering as against the XGL rendering engine then all you need is to install the appropriate drivers for your ATI graphics card.


Install Drivers

For newer ATI cards, click here for 1-click installation for the latest fgrlx drivers

The above will start YaST package manager to install the required drivers.

Now, make configure X to use the newly installed ATI driver.

opensuse11:~ # aticonfig –initial

Restart your X Server by typing <CTRL>+<ALT><Backspace> twice in 2 seconds or alternatively, simply logout/login or reboot your computer.

There was an issue identified with ATI Radeon Express cards. Once, installed run the following:

opensuse11:~ # glxinfo

will show that the direct acceleration/fglrx driver is not being used. To workaround the problem switch to Runlevel 3 (Text mode with Network support)

opensuse11:~ # init 3

Once in Run level 3, login as root and run the following:

Rename the xorg.conf file

opensuse11:~ # mv /etc/X11/xorg.conf /etc/X11/xorg.conf_orig


Re-initiaize and configure X server to use ATI drivers

opensuse11:~ # sax2 -r -m 0=radeon
opensuse11:~ # aticonfig –initial –input=/etc/X11/xorg.conf
opensuse11:~ # sax2 -r -m 0=fglrx

This should help.

AIGLX rendering is faster because of using hardware rendering for OpenGL and Xvideo.

Eedit the /etc/X11/xorg.conf file and check the following entries are already in the configuration file, if not found then add them as required:

Under Section Device

Section “Device”
Option      “XAANoOffscreenPixmaps” “true”

Under Section ServerLayout

The following option enables AIGLX rendering. Enabled by default in openSUSE 11.0.

Section “ServerLayout”
Option      “AIGLX” “true”

Under Section Extensions

Section “Extensions”
Option   “Composite”  “Enable”

Once any of the missing entries are added, restart your X Server by typing <CTRL>+<ALT><Backspace> twice in 2 seconds or alternatively, simply logout/login or reboot your computer.

This gets your ATI Graphics card ready for the Compiz-Fusion desktop experience.
