Bug ID: 442015
Summary: Screen looses content randomly, just black
Product: kwin
Version: 5.22.4
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: mail_to_...@gmx.de
Target Milestone: ---
SUMMARY
Since about a week now (after running some system updates) my Notebooks screen
will suddenly turn black after something in between 1 min after plasma has
completely started (rare) and more often something between 10 min and 30 min.
The backlight is still on, I can adjust the brightness. Moving the mouse after
some idle time makes the screen turn on (changes from pitch black to backlit
black). I can ssh in and run commands. Videos in firefox continue playing and
can be paused/started by mouse clicks. I can often press the power button and
then enter and it will shutdown. Plymouth will shortly show the Kde neon logo
before the computer turns off.
Pressing Shift+Alt+F12 does nothing.
When I ssh in, kwin_x11 is still running.
STEPS TO REPRODUCE
1. Start Notebook
2. Do anything or nothing
3. empty/black screen
