Disabling compiz seems to have fixed the freezing. There might be a shorter way to do this, but this is what I've done.:

Then on the blue icon that appears, right click, go to Select Window Manager, and choose Metacity. -- 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/781402 Title: Ubuntu 11.04 / Unity freezing when screen is 'woken up' _______________________________________________ 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
