Help Kubuntu, Nvidia driver, X server

Hey guys I just installed yesterday the latest version of Kubuntu (so expect many more questions to come :) and I tried to install the latest Nvidia driver by using the following commands, which i found on various web sties.
the driver starts to install, but then it says that there is an X server running and it cannot continue the install. How do i stop the X server? I thought the kdm stop was suppose to stop it. Any help would be appreciated.

Hi!
Check this Trick from the Linux Tips and Tricks here on bytes. You're looking for something like xserver, xorg or X11.

Thanks for the link, I'll be sure to look more closely next time on the tips section. The weird thing was after i started kubuntu again i ran the commands i posted above and it stopped the xserver. I now have another problem, but I'll start a new thread for it.
