I get requests from users and see questions all the time for "where did my xorg.conf go in the latest Ubuntu or Fedora?", though it is usually a bit more of a flame.
The quick answer... press Ctrl+Alt+F2 or similar to log into a TTY console, or type 'init 3' into a root X terminal.
If you haven't already, log in as root and kill X or type 'init 3' if you want to be heavy handed. Then run:
X -configure mv ~/xorg.conf.new /etc/X11/xorg.conf
xorg.config in two commands. Run the 'init 5' command to get back to your GUI login (or kdm or gdm or startx, etc if you know what you are doing. Worst case remove the .conf and restart.)
If you are advanced enough to edit an xorg.conf, the above should be a cakewalk and you shouldn't complain about it.
Regardless, you should investigate 'xrandr' which makes it simple to do runtime adjustments.
If you are a newbie, look into a gui. KDE has KRandRTray which makes controlling outputs and resolutions a breeze. Don't forget to toggle the output on with the Fn key if you are a laptop user.
Needless to say, Xorg is moving in the right direction. Stop complaining about it.
