[Bug 474421] [NEW] blank LVDS when using KMS

[mnemoc]

Public bug reported:

Binary package hint: xserver-xorg-video-intel

Using i915 kernel module (2.6.31-14-generic) and xserver-xorg-video-
intel (2:2.9.0-1ubuntu2) in karmic for x86_64 in my HP Compaq 610, the
panel is always black (but On) regardless of what i try with xrand. It
worked perfectly until I upgraded to 9.10 this morning.

The problem vanishes when disabling KMS in i915
