I'm in the middle of trying to setup dual monitors on ubuntu and would like to backup my xorg.conf...

The documentation I've been thus far say to do the following:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup

But I don't see the xorg.conf file anywhere... Am I missing something? Where is this located?

Quoting from

Current version of don't use a xorg.conf by default but try to recognize everything automatically. If you create a xorg.conf it will be used.

If you use a NVidia card Mikey, just use: sudo nvidia-xconfig (do a reboot) and then sudo nvidia-settings from the normal environment. Best way to set it up. – Shiki May 16 '10 at 16:39
