Bug ID: 484931
Summary: Waking the screen up right as it enters sleep breaks
the session
Classification: Plasma
Product: kwin
Version: 6.0.3
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: bizy...@zoho.com
Target Milestone: ---
SUMMARY
After a period of inactivity on the lock screen, the monitor is automatically
turned off. If I shake the mouse to wake it up again as soon as it happens (or
right after that), the monitor's backlight is re-enabled, but there is no image
— just a black rectangle.
So far, I have not found a way to continue using my computer when this happens.
I am able to enter a TTY and issue "systemctl reboot".
STEPS TO REPRODUCE
1. System Settings > Energy Saving > When locked, turn off screen: 200 sec
2. System Settings > Screen Locking > Lock screen automatically: after 1 minute
3. Wait :)
4. As the screen is turned off, shake the mouse.
OBSERVED RESULT
The screen is re-enabled, but the signal is just darkness.
EXPECTED RESULT
I can see the lockscreen.
