You just need to plug the DVI cable in. I have the same computer as you, 
also running Edgy. I also have a problem:) It is connected to a 23" LCD 
monitor. When running at the monitors native resolution, I get no output 
from the DVI.

Ubuntu boots fine and until X starts everything works OK. Once X starts 
I get output from the DSub, but not the DVI. Both outputs work correctly 
at lower resolutions. One of my New Year jobs is to find out why this
