More information! It is indeed a bug in Compiz (or maybe Unity)! I get a fully usable desktop (in fact, I am using it right now) if I quit to a TTY and replace unity with metacity.
More info on the segfault: it appears to be happening while loading unityshell, because with verbose output it is very easy to see the pattern. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/775060 Title: Random GUI "freezes" in Natty (can only move the cursor) (might be a segfault) To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/775060/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
