Silky smooth accelerated graphics on ATIRadeon Mobility 9000 laptop with Ubuntu 6.06

I was initially very impressed with the ease of installation and device detection on my 3 yr old laptop. Over the last couple of weeks of downloading and setting up software though, it was obcious there was something not quite right with the video drivers… the update rate and screen refresh was not as slick as what I’ve been used to in XP.

I did some searching around and found links to the ‘fglrx’ driver, a Linux display driver from ATI. Check out my post on getting this working – read more here.

Now I’ve got this installed and configured correctly, my screen updates, scrolling, moving windows around the screen etc are *very* smooth… it looks pretty impressive…

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.
