So did you try to run nivida-xconfig???   It should make you a new file in   
/etc/X11

The file that needs to be changed (lots of luck doing it manually)  is

/etc/X11/xorg.conf

which isn't used anymore (or as much) in later systems since they do most of 
the configuring on the fly.

So  nivida-xconfig   should build you a new file.
