Ubuntu, high res & multiple screens.

[BoomAM]

Hi.
Every now and then i boot into my Ubuntu partition, and then 5mins later, i reboot and go back to Vista.
Reason?
It wont detect my second monitor, and wont display either at 1920x1200.

The current install is the one prior to 8.04, upgraded.
My final shot at getting at least the proper res on one is a fresh install...?


Anyone got any tips?

ATI.
Dual cards.

So basically then, with 2 ATI video cards, wanting dual screens and both at their full res, im knackered? .
