Hello!
1.Go to nvidia website and download the latest driver for your video card!
2.Kill the X server of your session by presing CTRL+ALT+BACKSPACE.
3. cd where is located the driver you just downloaded.
4.sudo sh xxx (where xxx = the name of the driver) and hit enter,then choose Yes.

If you are tired go to sleep, otherwise open a shell and follow along.
# apt-get update
Wait until prompt returns, then.
#apt-cache search nvidia
Then find the driver and
# apt-get install said driver package.

Because my ZOTAC NVIDIA Geforce GTX285 wasn't on the premade driver list, this was my best way to install, I think. I'm kind of super noob so maybe there's an easier way, but at the moment this was =)
