Same problem around here. Disabling Sync to Vblank wont work for me. The bug has appeared with 2 variants: After long time of inactivity (everything freezes, except the mouse) and after suspending the notebook by closing the lid (black screen, mouse still can be seen and moves)
I'm running an M880 RAdeon HD 6650M on ubuntu 12.04 OS still works, since CTRL+ALT+F1 works fine. However pressing CTRL+ALT+F7 return you to the stuck screen -- 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' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/781402/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
