This has been a problem for me for probably about a year. It often happens with vmware player open in my gnome-shell. I've become so used to it that I was actually looking for a keyboard shortcut to launch the killall gnome-shell! It happens to me two or three times a week so if someone tells me how, I can easily give you a dump of gnome-shell/X/etc when it happens. I've colleagues with the same problem.
For the record I'm using 12.04 and gnome-shell 3.4.1. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1218309 Title: Gnome-shell freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1218309/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
