I may have the same problem with acer travelmate 4001lmi (mobile radeon 9700 / 64mb). I disabled compiz, but as soon as a access the screensaver applet or any other 3d apliccation (glxinfo, glxgears...) the system freezes.
This started during 08.04 alpha (even the live / install-cd was affected). It was fixed in the stable version but after updating the system, it reoccurred. Fedora9 shows the same symptoms. https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/195721 https://bugs.launchpad.net/ubuntu/+bug/203007 -- X freezes in drmCommandWrite() when Compiz is enabled on ATI Radeon Mobility 9600 https://bugs.launchpad.net/bugs/195051 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
