Install (K)ubuntu Breezy Step 3: Nvidia Graphic Card

If you have a Nvidia Graphic Card, you should do the following:

Open a terminal and type (one after the other):

sudo apt-get install nvidia-glx
sudo apt-get install nvidia-settings
sudo nvidia-glx-config enable

Reboot - during the boot you should have now a screen with the Nvidia-Logo.

Update: You can also use Automatix to do that.
