Dual Monitor support problem Dell D630

[jeanM]

Hello all.

I've been using Ubuntu for about 6 months now. It's the best. I have one small problem. I have searched lots for answers to this particular problem, but have yet to find a solution.

I am using Intrepid on a D630. I have a Dell 1905FP monitor - native resolution is 1280x1024. The problem is with the dual monitor setup, I always end up with 1024x768 on the 1905FP. Here's what's in my xorg.conf:
