Bug Description
I have worked on A LOT of trial and error (even trying experimental 3.4.x drm kernels with 12.04) for this problem.
However, 10.10's LiveCD seems to be a sweet spot where I have some of the problem (no video for plymouth) but not all of the problem, X comes up.
Any of the newer releases both Plymouth and Xorg fail.
I do get this error on for 10.10, 11.04, 11.10, and 12.04:
[drm:intel_
[drm:drm_
[drm:drm_
[drm:intel_
[drm:drm_
[drm:drm_
But perhaps that's a red herring. Since that error is present here in 10.10, and yet X is running.
That error led me to this bug:

and I even tried the kernel mentioned there (with 12.04) but I still didn't get any video.
Perhaps this is the problem? (dual channel LVDS issue)

Ultimately I'd like to be runing 12.04LTS. But it seems like I'm stuck at 10.10.

I have since figured out a little bit more.
The motherboard I've been using is a development board. This board can support a flat panel display that would be suitable for a laptop.
Unfortunately, I'm unable to convince the board that it doesn't have a laptop LCD installed. On Ubuntu 10.04.1 LTS (which I switched to because I sorta prefer LTS) I was able to tell Xorg that I didn't want it to use the nonexistent "laptop" display.
I believe all the LVDS errors are from the software trying to query this nonexistent display and failing.
Further, I believe that the newer kernels/ distributions are making little or no attempt to use the external display because of these problems.
Should I file a bug against 12.04?
