Same problem on Lenovo T61 with screensaver disabled. It mostly happens after a lock-screen.
on the console (ctr-alt-f1) tried to reload compiz and unity, this didn't help. reboot is not necessary, a simple pkill -9 -u <user-name> on the console will restart your X. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
