I am having the same issue, and it seems to happen when I'm switching workspace using Ctrl-Alt-[arrow] shortcuts. My screen doesn't freeze mid slide, but it freezes after it has slided to the next screen. I followed your method to back out to the terminal (Ctrl+Alt+F1) but when I press (Alt+F7) all I get is a blank screen. Can you confirm with me if it's Alt+F7 or Ctrl+Alt+F7?
While in console, I use "/etc/init.d/gdm restart" to get back to the desktop but this is no better than restarting the computer as I have to reopen all my apps! (Just speculation for now) It does not seem to happen when I switch workspaces using Expo mode, Super+W, although I've only been using it for half a day (avoiding Ctrl+Alt+[arrow]) as of writing this. I'm using nvidia GTX465 with nvidia drivers from ubuntu's repository. I'll submit my apport-collect in awhile. If there's anything I can help to diagnose this issue let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/815996 Title: Desktop occasionally freezes/locks up when switching workspaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/815996/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
