I am a Linux noob and could use a little help with an issue.
I am trying to achieve a very specific resolution and screen size (720x480 @ 59.94) for my headless Ubuntu 12.04.2-64 Desktop box with a nVidia GeForce 8400 GS card.
The machine is used primarily for ssh and the GUI (remotely). The restricted drivers have not worked for my situation. I have created and tried to change the xorg.conf file according to the man but I am not achieving the desired result. The edited xorg.conf file displays the desktop in the desired scale or resolution but the screen output always 1280x768. When I try and add DisplaySize 720 480 to the Monitor section it breaks the file and will not produce a desktop.
Here is the xorg.conf file:
