I would boot into Graphics Safe Mode, then utilize the command: sudo displayconfig-gtk
in a terminal. 1) click on the "Graphics Card" tab 2) click on the "Driver" area 3) Select and test the most appropriate driver based on your video card. When you find a situation that works, please record it for the future.
