I have an Intel DQ77MK motherboard, which has 2 DVI connectors, and a Core i7 3770S IvyBridge CPU. Under Ubuntu 12.04, the multiple display support does not work, and I am stuck with a single display. The second screen only shows all pixels as 100% red. Enabling the second screen in Displays in System Settings does allow me to move windows and the mouse cursor to that screen, though I cannot actually see anything on it, as everything is red. For now I have had to force it to mirror displays, to avoid moving things to the second screen.
Also, on the daily live image for Quantal, the system appears to freeze when X starts, and I am left with the primary screen being black, and the secondary screen being full red. The plymouth framebuffer is a fuzzy green image, and everything turns black when X comes up.

Sorry, installing nvidia is not going to work for now. I'm working with airlied on prime support for it though, so if lucky it lands in quantal or 12.04.2. Things will probably start working in x1.13 but it will probably still need manual configuration then.
