Spanning dual head using xrandr and a virtual resolution

I have a Lenonvo 3000N100, on which I am running a fresh install of Fedora 10. I would like to have the ability to run a dual monitor setup when I am at my desk. The external monitor will be attached via VGA, be to the right of my laptop, and has a resolution of 1280x1024.

I want to use the command: 'xrandr --output LVDS --mode 1280x800 --output VGA --mode 1280x1024 --right-of LVDS'

I would like to run this when I connect the monitor. In order for it to work, I know I need to add a line to my xorg.conf file under the display subsection: Virtual '2560 1024'

I generated a basic xorg.conf file, and rebooted. The laptop booted just fine. I then added this Virtual line, and rebooted. This time the X server starts, but when I get to the login screen, it does not allow me to login. Instead of displaying the username, it simply says "other". The computer is then locked up.

I booted to runlevel 3, and used startx to hopefully get some debug info. The X server begins to load. I can see the background, but it stops loading and locks up. Ctrl + Alt + backspace does nothing. I have to hit the power to reboot.

Has anyone encountered this? I'm at a loss here.

Thanks for your help.
