I'm nut sure if I'm looking at exactly the same bug, since in my case the
displays stay black, no output what so ever.
The displays are all connected to the digital output.
I'm including the dmesg of one of my machines with drm debug.

I created a test kernel using the raring master-next branch. It would
be great if you could test this kernel to confirm it resolves this bug.

I have reported the same symptoms earlier with an Intel Core i5 PC
running Quantal, bug 1029865. I have installed the kernel from comment
#7 also there and booted it, but that machine still shows the ghost VGA
display and due to that comes up with a 1024x768 login screen. I have
checked with uname
I am currently testing the test fixed kernel. Will provide feedback
shortly

I have tested your test kernel from comment #11 on both machines now and
get exactly the same results as with the kernel from comment #7. On the
laptop (bug 1156548) the problem is solved by both kernels and on the PC
(bug 1029865) the problem is not solved by both kernels.

Till: this bug is about raring, not quantal. And if you have issues on

Now I have upgraded the PC to Raring now and there the problem still
persists. According to uname -a I am using the kernel 3.8.0-13-generic
#23~lp1156548v1. I hope this is a kernel intended for Raring (Quantal
has 3.5.x kernels).
