[Bug 561802] Re: [i915] blank screen on Latitude E6410

[Michael Elkins]

Dell Latitude E6410, Core i5, 4GB
BIOS A03
Intel Graphics (00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02))
Ubuntu 10.04

Kernels: 
linux-image-2.6.36-020636rc3-generic_2.6.36-020636rc3
linux-image-2.6.35-20-generic-pae 2.6.35-20.29~lucid1

With stock boot params "quiet splash", the backlight comes on, but the
screen is black almost immediately after hitting return in grub2. I can
hear the GNOME sound when gdm starts up, so the machine is still
running, but the screen stays black.

With boot param i915.modeset=0 I can see the kernel message text until X
starts, then the screen goes black with the backlight still on, but the
kernel panics and I see the two flashing numlock and capslock lights
blinking. Machine is unresponsive.

The only kernel that allows me to boot into X so far is linux-
image-2.6.32-21-generic-pae.  All newer kernels exhibit the same
behavior described above.
