I am having problems with a dual monitor setup with my X200 tablet and an ultrabase. I have two Dell monitors, a 1905FP connected on the vga port as primary, and a 2001FP as second, connected on the displayport with a Lenovo displayport-dvi adapter. This has been working fine for a couple of months. I am running windows 7 professional sp1, with all relevant updates. I have the most recent video driver installed (126.96.36.1995).
Today, the dvi ported display disappeared - the intel control panel only sees 1 monitor if the laptop lid is closed. If the lid is open, the system works fine in dual display using the built-in and the vga port, but I cannot get it to see the dvi monitor. I have tried using a new third party displayport-dvi adapter, with no change. Here are some interesting observations:
Any ideas on how to fix this?

I have similar problem. I think "system topology" you refereing to is only available on nVidia video card. He and I have intel video card and I can't seems to find "system topology".
