This has probably been asked but I will ask again just because i am naughty.

Okay I boot up knoppix, everything boots up nicely and then after a few minutes my screen goes blank. I thought it might have been the screen saver but i made sure it was turned off then rebooted. The same thing happened. I get a black screena nd no mater what combination of keys i press, it won't give me back my screen.

Any suggestions.
