Priority: medium
Bug ID: 80008
CC: intel-gfx-bugs at lists.freedesktop.org
Assignee: intel-gfx-bugs at lists.freedesktop.org
Summary: Random loss of video output, laptop connected via
docking station to two external (DVI, VGA) monitors
rotated in portrait mode
QA Contact: intel-gfx-bugs at lists.freedesktop.org
Severity: major
Classification: Unclassified
OS: Linux (All)
Reporter: ilakast at yahoo.com
Hardware: x86 (IA32)
Status: NEW
Version: XOrg CVS
Component: DRM/Intel
Product: DRI
When video output is lost, Fn+F7 does not help restoring video into the
internal laptop LCD either. Only switching off completely and rebooting is the
solution at the moment.

Jun 13 23:33:15 t61 kernel: [29969.988061] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
Jun 13 23:33:15 t61 kernel: [29969.988063] [drm] Please file a _new_ bug report
on bugs.freedesktop.org against DRI -> DRM/Intel
Jun 13 23:33:15 t61 kernel: [29969.988064] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
Jun 13 23:33:15 t61 kernel: [29969.988066] [drm] The gpu crash dump is required
to analyze gpu hangs, so please always attach it.
