Bug ID: 503030
Summary: Plasma brightness setting overrides monitor OSD value
after sleep or reboot
Classification: Plasma
Product: plasmashell
Version: 6.3.4
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Power management & brightness
Assignee: plasma-b...@kde.org
Reporter: rocking...@proton.me
Target Milestone: 1.0
SUMMARY
Adjusting the brightness via the System Tray in Plasma works well with my
external monitor (MSI MAG274QRF-QD) — the new value is correctly reflected in
the monitor's OSD. However, if I manually change the brightness via the
monitor’s OSD, Plasma does not register the new value. After a reboot or when
the monitor wakes from sleep, the brightness reverts to the value previously
set in Plasma.
Ideally, Plasma should detect the brightness change made via the monitor OSD
and update its internal setting accordingly to prevent this override.
STEPS TO REPRODUCE
1. Adjust brightness via the System Tray (Brightness and Color).
2. Manually change brightness using the monitor’s OSD.
3. Let the monitor enter sleep mode.
4. Wake the monitor.
OBSERVED RESULT
Brightness resets to the value last set in Plasma.
EXPECTED RESULT
Brightness remains at the value set via the monitor OSD.
