Robert, since this is reproducible for us on a stock Natty install, I've generated an apport report on Natty, and I'm attaching it here.

Steps to reproduce:

1. Configure T420s in the BIOS to use Intel integrated graphics.
2. Install Natty with the Ubuntu desktop task
3. After install, GDM and X will start normally.
4. Shut down the laptop
5. Power on the laptop. When X starts, the display is corrupted as David explains above--2/3 of the screen is black and 1/3 is black and white striped. At this point, you can fix the display by closing the lid to suspend and then opening the lid again.

I should point out that not all T420s Thinkpads exhibit this problem. We have some, type 4174AY9, that have this problem. But also I have a 4174A11 model that doesn't have this problem.
