How can I get X server to stop while installing nvidia's proprietary drivers on Arch linux?

I am currently in the process of immigrating to Arch Linux. I am trying to install the drivers, however it keeps telling me that "X server is running". I have looked everywhere and CRTL+ALT+BACKSPACE just restarts Gnome before I even get the chance to log in to tty. And X server is apparently still somehow running? I tried to kill X server, but the shortcut didn't work, and even in tty2 the error shows up, so how do i get rid of the X server? Does it have something to do with X11 the window manager? If so how do i kill it?
