I have upgraded to a new version of Ubuntu now, which is using 3.10.0-6,
as well as the latest version of the BIOS for this board, from Intel.
The second screen is completely red, and link train errors are
occurring:

The bug is certainly not fixed. There is no new information, because no
further information has been asked for until now, and I've purchased a
cheap PCIe NVidia card, so that I could get both monitors working in the
meantime, as being able to use both of my monitors is necessary. I
didn't buy a second one to never use it.

Title:
  8086:0162 [Intel DQ77MK] Multiple Displays not working

Status in X.Org X server:
  Confirmed
Status in “linux” package in Ubuntu:
  Confirmed
Status in “linux” source package in Precise:
  Confirmed

Bug description:
  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.
