Black screen on exiting full screen games.

http://forums.opensuse.org – OpenSuse 11.3 with nVidia drivers. I have the screen working fine though it only runs in 1600x1200@75 using the nVidia driver (GTX260 card). When I play a game in full screen mode all seems OK but when I exit the game then I just get the mouse pointer on a black screen. There must be something present since the cursor changes as I move it, normal pointer -> hand over a link etc. It's just that black on black isn't very readable. (Distributions)
