Unfortunately I couldn't find any automated installation for my Nvidia GeForce 9600 GT, so I found a way to install it manually and get it to work with my X server.
Get the driver here.
(My installation assumes you rename the file "Driver.run" and put it in the '/home/UsernameHere' directory.)
Right click on the driver file -> properties -> Permissions -> Allow executing file as program
Get the libc6-dev package from the Synaptic Manager. If it prompts you to install dependencies, do so.
Go to Applications -> Accessories -> Terminal (Or Konsole, or any terminal.) and Enter:
This will close the X server and leave you at a screen asking what you want to do. Press the arrow keys to highlight the "root" option and press enter. Go ahead and type in:sudo init 1
This will run Nvidia's installer Go through the steps. When it finishes, you're back at the root prompt. To finish off the installation enter:'/home/UsernameHere/Driver.run'
Change the last line to readnano /etc/default/linux-restricted-modules-common
Press ctrl+x to save it, y to confirm and enter to finish. Now reboot the computer. (You can use the command "reboot" to do this.)DISABLED_MODULES="nv"
Hope this helps. Only tested with the 9600 GT driver, but I see no reason this shouldn't work for other 9 series cards.
