Black screen on any game

[Surttep]

I am using ubuntu 14 and a geforce gt 630 331 driver.

Everytime i launch any game on steam a few seconds later my monitor lose signal and i keep listening to the game music, so tried playing a few others non-steam games to see what happens, and i got no problem with those games.

If unnistall the nvidia driver and play a steam game using nouveau driver i don't get any problem.

Maybe add "-novid" to game's launch options.
