I experienced this bug on 11.10 and switch to 12.04 last week, on the 11st of May. -> The desktop continued freezing randomly when I switch workspace as described in bug #880768.
Right now, the bug has desappeared but I am not sure I have done anything for that. What I can see, is that the design of the popups (when you use Alt-tab or Ctrl-Alt-arrow) has regressed. They are not "pretty" any more (with transparent backgrounds) as they were when the desktop froze before. If I go to the historic changes of the packages, I can see that "zenity" has been upgraded on May, the 12th. I also installed the x-server-xorg- video-install-intel-dgb and inteltool packages, but I did not do anything with them really, so I am not sure it has anything to do with the new status. Do not hesitate to ask for more information (providing the command line to do if any, I am far from being an expert) Cheers Emmanuel -- 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/compiz-plugins-main/+bug/815996/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
