Configuring ATI Radeon Linux drivers on Ubuntu

Download the ATI Radeon drivers ‘fglrx’ from the Synaptic Package Manager.

Edit /etc/X11/xorg.conf:

Add to ‘Section “Module”‘: Load “GLCore”

In ‘Section “Device”‘ change “ati” to “fglrx”

After restaring, check output in glxinfo – direct rendering should be ‘yes’ and ‘renderer string’ should show ‘MOBILITY/RADEON 9000 DDR Generic’

Initially I had errors running glxinfo – this post here explains the problem and provides a fixed (older?) .so file to replace one in the lates fglrx dirver.
