I have Ubuntu 10.10 x86_64 with Nvidia 9800 gt and Nvidia driver version 270.41.06

My video card has two DVI sockets, but I only use the single monitor configuration. Now, I think the main DVI socket might be busted, so I want to try to enable the other as the main one, however, I don't know how to achieve that. I tried just plugging the monitor in that socket but it won't auto-detect it (it would have been way too easy to just work).

This is my xorg.conf:
