# mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
# mv xorg.conf.new /etc/X11/xorg.conf
# xinit
# startx
open your resolution settings and see if new ones appear

I tried doing this and when I do X -configure I get this error.

user not authorized to run the X server, aborting.

I am the only user on this computer, and I am set up as an admin. Maybe Ctrl-Alt-Backspace doesnt stop X?

All of those commands have to be run as root, try running `sudo X -configure`.
