Red Hat Bugzilla – Bug 203707
"compiz" window manager locks up system
Last modified: 2007-11-30 17:11:41 EST
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):
Steps to Reproduce:
1. Log in to "GNOME" session.
2. Enable "desktop effects".
3. Disable "desktop effects" or log out.
System locks up.
System terminates "GNOME" session gracefully.
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
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.
