Package: src:linux
Version: 4.14.2-1
Severity: minor
Dear Maintainer,
For quite some time I've been wondering why laptops running Debian
restart the displays while entering suspend to disk/hibernation.
Since this is now happening with three of my laptops I decided to
file a bug, and since this happens with both Xorg and Wayland I blame
kernel for now.
When starting hibernation from userspace, all my Debian unstable machines
freeze the display and then shut it down. But a few seconds/milliseconds later
the display is restarted with full brightness with the content
that was available on the screen before entering hibernation.
This sounds like a bug or a bad configuration in display drivers or graphics
stack.
My expectation for entering hibernation, which can be wrong, is that
kernel freezes userspace processes and shuts down all drivers. I would have
thought that Intel i915 drivers would support this completely and shut down
the display only once.
When I enter:
# echo disk > /sys/power/state
display goes black (or turns of) immediately on this Thinkpad X1 Carbon laptop
with Intel chips. Then LED on the power button blinks for a few seconds
and then display comes back with full brightness and power button LED stops
blinking. Then a few seconds later the whole machine shuts down.
This wakeup of display seems odd. It happens on this machine as well as
a Thinkpad T60 and HP EliteBook running Debian unstable with Xorg and Xfce.
Only thing in common with these machines is Debian unstable and Intel chips.
What could be causing this and is there maybe a simple fix or configuration
option available?
