You may want to know that linux has its own drivers and you only need to go to its graphical environment (please ask here for help if you already aren't in).
But for gaining full 3D support and more features, please download Linux IA32 driver from nVIDIA (www.nvidia.com
) and read its "readme.txt" carefully, at least the first sections of it. If you didn't succeed, mail here again.
