I just installed Lubuntu 13.04 on my MacBook Pro 6,2.
It seems to work fine. However, once in a while, when I am logged in and using the computer, the screen will suddenly become blank. (Sound still works -- I know this because one time the screen went blank when I was watching a video.)
Does anyone know what might be causing this? (I am using the NVIDIA driver.)
Edit: I have installed Lubuntu 12.04 to see if this would fix the problem; however, the unpredictable blank screen problem is still there.
