I just plugged mine in and it worked, so you're going to need to add more details. – Ignacio Vazquez-Abrams Oct 15 '10 at 22:34

Had the same problems with a Radeon x1400 in Ubuntu. Finally, I was able to activate the external out with xrandr. In Ubuntu, it can easily be installed if it isn't already.

But as mentioned, you need to give more information: Which OS? What "outs", vga, dvi ?
