You've probably got XGL installed.
Uninstall XGL I think it could be called, xserver-xgl.
If you have that installed, get rid of it, and make sure that AIGLX is enabled in your xorg.conf.
That was the biggest problem I had with the ATi drivers, doing that fixed it.
That seemed to work; certainly I could start Termulous and CrackAttack, which (I believe) are both GL games.
That said, there is a bit of an annoying flicker - could this be my monitor refresh rate? Changing the settings in the Catalyst Control centre don't seem to make a difference.
Go to Preferences > Screen Resolution and see tinker with a few different settings there to find one that doesn't flicker maybe??
If you're using an older monitor, then a lower refresh rate is what you're after.
I'm using a 2004 model Dell monitor, running it at 1024x768 @ 85hz. It runs fine on my X1600.
CCC:LE I find it actually quite useless.
Maybe it'll have more use in a few releases.
I've had no issues with the graphics drivers since I worked out my problem (The XGL vs AIGLX thing)
I'll check it out, although I'm using a half decent (generic) widescreen TFT I bought last year.

Well, I have no idea...
Probably best to create a new thread.
If you do start a new thread, I'll watch it in case I can help.
