display

I'm running 12.10 on a dell e5400 laptop and I used xrandr to get the dual monitors working that I connect through a laptop dock. I used xrandr again to switch back to the laptop display when I undocked. The problem is, after a restart, the laptop seems to want to come back up with the dual monitor configuration and the laptop screen stays blank. I can boot into single user mode but I'm not sure what to do from there to get the display settings reset. Any ideas? There's no xorg.conf file so I'm not sure where the settings are stored anymore.

Thanks.
