I got the same issues on a Thinkpad R61 with the GM965/GL960 and a desktop computer with the same graphics controller. Both upgraded to 8.04 beta - latest updates installed. The system locks up at least once a day - on laptop and desktop computer. Logging in via ssh / killing compiz.real is the only solution.
It seems that this problem occours only when I am doing drag & drop operations on the desktop - no matter in which program (experienced it in nautilus, gimp & amarok). Can somebody confirm that? -- 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
