jpds posted me the pertinent bits from the .xsession-errors: ** (gnome-fallback-mount-helper:1522): DEBUG: ConsoleKit session is active 0 gnome-session[1430]: WARNING: Application 'compiz.desktop' killed by signal gnome-session[1430]: WARNING: App 'compiz.desktop' respawning too quickly gnome-session[1430]: CRITICAL: We failed, but the fail whale is dead. Sorry....
So, compiz is definitely getting stuck in a loop. gnome-session notices it's failing and (I guess) restarts the session. I'd follow the usual compiz troubleshooting steps from here. Enable debugging; test a guest session; run compiz through gdb; disable compiz plugins one by one, etc. ** Package changed: xserver-xorg-video-intel (Ubuntu) => compiz (Ubuntu) -- 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/929655 Title: Unity randomly freezes after 11.10 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/929655/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
