I'm still experiencing this bug as well. HP nw9440 notebook, Nvidia Quadro FX 1500M, using nvidia driver v169.12, up to date hardy.
It happens most frequently while I'm scrolling a web page in firefox using the arrow keys, but has happened during a cube rotation as well. Screen is froze, mouse pointer moves. I am able to alt-sysreq-r to get to a console where I find compiz.real using a reasonable amount of resources (around 32m resident mem and 3% cpu). stracing the process all I see is it polling 'poll([{fd=11, events=POLLIN|POLLPRI}], 1, 1000) = 0'. I killall -ILL compiz.real and metacity takes over. The one consistent thing I am able to note every time this happens, is at the end of my Xorg.0.log: (II) NVIDIA(0): Initialized GPU GART. I noticed on the same 'SetClientVersion: 0 9' line on a couple of the above commenters Xorg.0.log, too. I'm suspicious of the driver, I think it's freaking out under certain circumstances but I still can't pin down exactly what triggers it. The attached Xorg.0.log is a session where the freeze occurred twice, after killing compiz.real and metacity taking over, I reloaded compiz using fusion-icon and it happened again shortly after. ** Attachment added: "Xorg.0.log" http://launchpadlibrarian.net/14078623/Xorg.0.log -- compiz randomly freezes X https://bugs.launchpad.net/bugs/176589 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
