I think this is a video card problem. Using nVidia geForce 8400 GS.

After suspending the computer and turning it on,  the computer was
working (hard drive noises and num lock led in the keyboard was on but
the screen refused to response, just black screen).

No suggested keyboard combination turned the screen on.

Tried the Compiz solution suggested above and it worked sometimes.

Today I finally tried using another driver version

Selected System->Admin->Additional drivers-> selected the 173 version
(not the recommended version) and it seems that the problem was solved.

You can try using other drivers for you specific video card.

*By the way, had the same problem with this video card also in WinXP
(solved it in the same manner), so I don't think it's an Ubuntu problem.
