When this happens attaching gdb to compiz shows it is stuck waiting in a call to glXWaitVideoSyncSGI so it's not going to be a compiz issue here.
Upgrading to 2.6.38 didn't solve it, I still get this every other day or so. Next time it happens I'll see if I can get any info. Apport doesn't collect any info, probably because the driver failed to restart the GPU. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. https://bugs.launchpad.net/bugs/708998 Title: Desktop freezes intermitently _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
