I was reading something someone posted and the said to press Ctrl+Alt+backspace so I did that and it got rid of my X server problem but now I can get out of it will someone please help.
Ok so, if you hold down CTRL+ALT+F1 , then login as your user,
Then enter password for root
then when your logged in as root, type
this should of disabled the X server.
then when your done with your nvidia drivers etc type
that will take you back to what you was originally using (most likely)
hope that helps?
