Disabling compiz seems to have fixed the freezing. There might be a shorter way to do this, but this is what I've done.:
In Ubuntu Software Center find and install Compiz Fusion Icon. Run it: Applications -> System Tools -> Compiz Fusion Icon. 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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/781402 Title: Ubuntu 11.04 / Unity freezing when screen is 'woken up' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
