I'm having an issue with waking up my laptop from Suspension -- the screen lights up but remains black and I can't log back into the OS! This happens if I actively press the power button and choose to Suspend. If instead I go away from the laptop, the screen goes off after some time. When I come back and say, move the touch-pad I'm prompted to type my user and password with the typical GNOME screen.

I've faced this problem with previous Linux distros but can't remember how I fixed it. I'm guessing it was installing Nvidia drivers that did the magick, I'm not sure. Has anyone had a similar problem? How did you fix it? I know one can "suspend to RAM" or "suspend to disk" -- how/where do you set that?

Here are my hardware specs:

Hope this helps.

Head off to Nvidia's website and download scripts for your PC.

Then find dkms package for your distro (.deb or .rpm).
