Summary: i915 closing laptop lid kills LVDS until reboot
Product: Drivers
Version: 2.5
Kernel Version: 2.6.29.1-70.fc11.i586
Platform: All
OS/Version: Linux
Tree: Fedora
Status: NEW
Severity: high
Priority: P1
Component: Video(DRI)
AssignedTo: drivers_video-...@kernel-bugs.osdl.org
ReportedBy: sai...@cs.cornell.edu
Regression: Yes
I am using KMS with a Intel 915GM card (on a Thinkpad X41 Tablet).
Closing and reopening the lid blanks the display permanently until a reboot.
Same for docking/undocking.
This happens even before X starts. This is not related to suspend/hibernate
etc. The problem occurs only with modeset enabled.
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.
I posted a video of the bug at:

I posted dmesg and Xorg logs in the following Fedora bz:
