Public bug reported: 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.
