Description of problem: The "compiz" window manager delivers working compositing functionality on my "Radeon 7200 PCI" graphics card which is powered by an "R100" chip. However, upon deselecting "dektop effects" or logging out from the "GNOME" session, the monitor turns blank instantaneously and goes to "power off" mode. The system does not respond to the keyboard anymore. Consequently, it is required to power off the computer manually to leave this state. Version-Release number of selected component (if applicable): compiz-0.0.13-0.16.20060817git.fc6 How reproducible: Always. Steps to Reproduce: 1. Log in to "GNOME" session. 2. Enable "desktop effects". 3. Disable "desktop effects" or log out. Actual results: System locks up. Expected results: System terminates "GNOME" session gracefully. Additional info: None
One of the recent mesa builds had a deadlock problem on r100 and r200 systems. The one I just built in rawhide should fix it, please give it a try and see if that fixes it. Make sure you test at least mesa-libGL version 6.5-26.20060818cvs, thanks.
Tried again after upgrading "X" related packages as of 2006-08-25 including "mesa-libGL-6.5.1-0.rc1.fc6" and no lock-ups anymore.
