Bug ID: 494588
Summary: Monitor screen brightness is reduced after monitors
are automatically turned off and on
Classification: Plasma
Product: kwin
Version: 6.2.0
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: mec...@gmail.com
Target Milestone: ---
SUMMARY
Monitor screen brightness is reduced after monitors are automatically turned
off and on. This is with a dual-monitor setup (unsure if relevant).
STEPS TO REPRODUCE
1. enable "Turn off screen" setting, set screen brightness to 100%
2. wait for monitors to turn off
3. use mouse/keyboards to re-enable the monitors
OBSERVED RESULT
The monitor brightness is set to 30% instead of 100%. The new brightness is
always 30%, but it is unclear where the 30% value is coming from - I do not
have the "Dim" option set, and there's no 30% in any related config tool that I
can find.
Of note is that sometimes only one monitor is set to 30%, and sometimes both
are. If I turn a monitor off+on manually, the brightness change is not observed
(in limited testing).
EXPECTED RESULT
Monitors set to 100%.
