I have this bug on three desktop machines which have been upgraded from 10.10 (where there was no problem) to 11.04 beta 2.
Logging out of Unity/Ubuntu Classic/KDE leads to a hard hang, where the machine logs out to a blank screen. The only way to shut down after this is to press the power button. Similarly, issuing a shutdown command (even as root in terminal) gives a hard hang. Two of the machines in question have discrete nvidia graphics cards and are running the nvidia driver, one is fglrx. I tried nouveau on one of teh nvidia machines, but it also hung on logout. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/766272 Title: Crash on shutdown/suspend/logoff -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
