Giving up on Ubuntu 11.04

I'm finally giving up on trying to install Ubuntu 11.04 on Lenovo T420s Core i7. Ubuntu 11.04 doesn't like the video adapter on this laptop. As soon as the installer tries to load the windows manager, the display goes blank with thin blue vertical lines covering 1/3rd of the screen from the right. 

I've tried finding the right video drivers, but to no avail. 

I'm falling back to Ubuntu 10.10, till somebody else figure this out. If you have any suggestions, please feel free to tweet me.

Thanks,

Saqib
