Public bug reported: It happened to me twice in the last few days. Sometimes when I open laptop's lid some time after locking the screen, the gnome-screensaver unlock dialog is missing, or even the screen is completely blank - I can only see a cursor. All apps are working, I can hear their sounds. I can even switch to the console using Alt+F1. I'm just unable to log back into my account and continue the work. The only way I know to deal with the problem is to restart lightdm, but, obviously, I lose all unsaved data. i915state doesn't show any problem.
My notebook: Asus K53SV i5-2410M HD3000+GT540M (works thanks to the Bumblebee) Please let me know if there's something I forgot about, but it's needed to fix the problem. It's probably the last thing stopping me from switching to Ubuntu for good.
