[Intel-gfx] i915 closing laptop lid kills LVDS until reboot

[Saikat Guha]

Hi,

I am using KMS with a Intel 915 card (on a Thinkpad X41 Tablet).
Closing and reopening the lid kills the LVDS until a reboot.

I can still fly blind (or log in over the network); and vbetool dpms
does manage to turn the backlight on or off, but the display remains
black. This happens both in X and outside of X (during boot for
example). This is not related to suspend/resume.

I posted a video of the bug at:

I posted dmesg and Xorg logs in the following bz:

I would like to help resolve this bug so I can use my laptop again. Please help!

cheers,
