Summary: 4400: vbetool dpms on kills the video
QA Contact: intel-gfx-bugs at lists.freedesktop.org
Severity: normal

Hardware: x86-64 (AMD64)
Status: NEW
Version: unspecified
Component: Driver/intel
Product: xorg
Hi. Having a problem with my laptop resuming video after S3 iff the screen was
in dpms off mode on suspending: screen blinks with my desktop contents and
immediately turns black with backlight on.
I think I managed to take hibernation out of the picture by playing with
vbetool.
'vbetool dpms off' turns backlight off as it should
'vbetool dpms on' turns backlight on, but screen still stays black.
'vbetool dpms on' turns screen black even without doing 'dpms off' first.
There's no way to restore from this state other than a reboot.
'xset dpms force off/on' works fine, but doesn't recover the screen after
'vbetool dpms on'
This is on Lenovo T440.
