I have the same problem. I use a freshly installed Ubuntu 12.04, and when I log under unity (3d) the GUI freezes after some time randomly. It can be when I surf the web with firefox or when I read a pdf file in evince. The mouse still moves on the screen, but nothing happens when I click somewhere. The system goes on working, for example, the music in rythmbox does not hang.
I think the problem is due to compiz, as no problem occurs when I log under unity2d. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 64bit completely freezes frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/993187/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
