I can't seem to find any that will actually allow me to install them. There are some in the software center, but they can't be downloaded. And the ones under nvidia's site, keep saying I'm running an X server, even if I kill it. Can anyone point me to an alternative download site?

Make a backup copy of your xorg.conf file so that you can copy it back to have a working xorg.conf if anything goes wrong with the nvidia driver installation and configuration.

On your keyboard, press ctrl + alt + F1 to switch to console. Use the sudo command to install the nvidia driver. Wnen it's all done, press ctrl + alt + F7 to switch back to your GUI desktop.

If that still give the error that X server is running, try opening a terminal and issue the command init 3 to switch from GUI (runlevel 5) to text mode (runlevel 3). Install the nvidia driver, then give the command init 5 to switch back to runlevel 5.

Run /usr/bin/nvidia-settings to configure your driver.

If you have any trouble getting graphics display, go back to runlevel 3 and copy the xorg.conf backup back to xorg.conf. Then come back with information about any error messages you get.
