Description Michal Schmidt 2009-04-24 14:16:40 UTC 
Description of problem:
I attempted to enable compiz using System -> Preferences -> Desktop Effects. X crashed instantly, putting me back to gdm login screen.

Version-Release number of selected component (if applicable):
xorg-x11-drv-ati-6.12.2-6.fc11.x86_64
xorg-x11-server-Xorg-1.6.1-6.fc11.x86_64
kernel-2.6.29.1-104.fc11.x86_64

How reproducible:
almost always

Steps to Reproduce:
1. Run desktop-effects
2. Push the button to enable the effects.
3. If by sheer luck you get to step 3, push the button again to disable the effects.
  
Actual results:
X will likely crash after step 2. If it does not, then it will almost certainly crash after step 3.

Expected results:
X should survive, with compiz running after step 2.

Additional info:
The hardware is ATI Technologies Inc RS690M [Radeon X1200 Series] [1002:791f] in a Toshiba Satellite Pro laptop.
