Need help installing nvidia drivers.
 

'Before beginning the driver installation, you should exit the X server.
In addition you should set your default run level so you will boot to a
vga console and not boot directly into X...'

This is what it says in the readme about installing the nvidia driver, how do I exit the X server and how do I change my default run level so I will boot to a vga console and not boot directly into X?

Just press CTRL+ALT+F1 to bring up a terminal, log in as root and issue the command init 3. That should put you in runlevel 3 (no X server). There is no need to reboot.
