Bug Description
Ubuntu crashes when I try to use ASUS Zenbook UX31E HDMI out (with Asus VS239H). It works nicely with console and LightDM login screen, but when I log in to Ubuntu/Ubuntu2D, screens (external and internal) go blank.
Restarting LightDM usually works (works as in "you'll see the LightDM login screen again), but sometimes this hangs the whole system.
Things you need to know:
1) lsb_release -rd

Release: 12.04
2) apt-cache policy linux-image-

3) I expect that X doesn't crash and I see output on both (or at least one) displays.
4) X crashes, both screens turn black. Sometimes external monitor turns red. Console usually works after the problem. LightDM has to be restarted.

- HDMI out doesn't work with ASUS Zenbook UX31E + [ASUS Zenbook UX31E] HDMI out doesn't work |
Tested with the latest upstream kernel, and the problem exists, (though I was able to get it once working after several LightDM restarts and HDMI cable attachs and disconnects).
Kernel's drm:intel errors have gone though.
