Bug ID: 483803
Summary: Screen does not turn back on after Powerdevil turns it
off.
Classification: Plasma
Product: Powerdevil
Version: 6.0.2
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

Target Milestone: ---

journalctl output covering the screen turning off and not turning back on
SUMMARY
When using Powerdevil's default settings, the screen turns off after 10
minutes. However, no amount of user input will wake the screen. The only way I
have found to wake it (short of a hard shutdown) is to unplug the monitor's
power cord and then plug it back in. Unlike other similar reported bugs such
as, https://bugs.kde.org/show_bug.cgi?id=477738, the monitor's backlight
clearly does not turn on at all. So, it is not a black screen that may or may
not have a cursor.
STEPS TO REPRODUCE
1. Have Powerdevil set to turn off the screen after a certain amount of time
(default is after 10 min)
2. Do not interact with the machine and let Powerdevil turn off the screen
3. Provide user input that normally would wake the screen (type on the
keyboard, move/click the mouse, etc.)
OBSERVED RESULT
The screen does not turn back on - the backlight remains off.
EXPECTED RESULT
The screen turns back on.

ADDITIONAL INFORMATION
The only way to wake the screen up is to unplug it's power cord and then plug
it back in. If I put the machine to sleep, then the monitor wakes up as
expected. This issue has occurred on both 6.0.2 and 6.0.1, but never happened
on 5.27.10 (the last plasma 5 version released on Arch).
The display is plugged directly into the dGPU, the iGPU is not used for
anything.
The attached file show the output of journalctl from the moment I stopped
interacting with the system until the screen turned off and I attempted to turn
the screen back on by interacting with the system (typing my login password,
moving the mouse, etc.). It also includes the screen's power cord being
unplugged and then re-plugged in.
