what the internal display displays

This i830M sits in an hp omnibook xt6050.

Booting 2.6.34-rc3-git8 (or 2.6.33.2) with an external display connected works fine (even X works).

When booting without an external display, the internal display starts showing beautiful, but nonsensical, patterns (photo attached).

I can ssh into the machine after booting, but it locks up after a couple of minutes. If I try to run "X -verbose 9", the notebook locks up just the same (after loading intel_drv.so).

I tried passing video=VGA-1:e to the kernel (because kernel log mentions VGA-1), and there is a difference: X starts up and there are no lock ups, but the internal display doesn't even blink and continues displaying the strange patterns.

dmesg logs for the two cases will follow. 

Any help would be appreciated. I would be happy to provide more information.

Looks like my bug could be a duplicate of bug 17902, but I am not certain.

This issue is affecting a hardware component which is not being actively worked on anymore.

Moving the assignee to the dri-devel list as contact, to give this issue a better coverage.

I believe this was the missing drm_mode_set_crtcinfo() bug. Please try a recent kernel.
