The package with Hardy for the Nvidia drivers doesn't actually work. I really wanted graphics acceleration so I decided to download the Nvidia drivers from their site.
Use Google and just go to Drivers, Linux, and pick IA32 or IA64. Download the driver (a .run) file to your home directory.
Press Ctrl+Alt+F2
Execute the commands:
sudo killall -9 gdm
sudo killall -9 Xorg
cd ~
sh N*run
Followed the instructions and all is wonderful. :)
(Oh, yeah, I replaced my old Compaq Presario R3000 with a Dell Latitude D830.)
