black screen after screensaver unlock
I've recently started getting unresponsive black screens after unlocking my computer. This happens both when I just have the computer go to the screensaver and when I wake from sleep.
I'll type in my password and just be greeted by a blank black screen with the mouse cursor visible and movable. The cursor sometimes even changes, like it's sensing what's behind it. The only solution so far has been to switch to a different tty and restart my session (service lightdm restart).
This started happening recently, so I'm thinking it might be related to the recent compiz upgrade? I'm using a multi monitor setup, for what it's worth.
Using Unity/Compiz on an Intel i3 laptop.
Does anyone have an idea how I'd go about solving this? Is it a known issue?
Thanks in advance.
