[Bug 561802] [NEW] [lucid] [i915] blank screen on Latitude E6410

[Launchpad Bug Tracker]

Binary package hint: xorg

During installation, bootup (plymouth) and while inside X, screen
remains blank. Switching VTs yields no results (screen remains blank).

This was done with today's daily desktop image, amd64: 10.04 (20100412).

I've been able to isolate the issue to possibly somewhere in modesetting
with the i915 driver, here are the tested cases:

 - Disabling modesetting with 'nomodeset' as a kernel parameter: boot messages visible in 'verbose', otherwise nothing on screen, X remains blank.
 - Disabling modesetting with 'i915.modeset=0' as a kernel parameter: results in a kernel oops, after briefly showing a simple "text" splash and showing corruption of that splash screen. X clearly never comes up, caps/scroll/num blink.
 - Disabling modesetting with 'nomodeset' and switching X drivers to 'vesa': nothing on screen during boot, up to a working, visible desktop.
