Comment 33 for bug 745304

Just as a notice: the described problem can be workaround by doing sleep (aka standby aka in-memory-suspend) after resuming from hibernation.

I.e. the system is restored from hibernation, the screen is broken (only the right 1/10 of the screen works). Then press Ctrl+Alt+F2, type your login, Enter, type your password, Enter, type "sudo pm-suspend", Enter (then your password again and Enter again if your sudo is configured to ask password), wait until it falls asleep, then move your mouse to wake it up -- and VOILA -- the screen now works ok.
