Bug ID: 497794
Summary: Powerdevil incorrect and random monitor brightness
up/down key brightness step
Classification: Plasma
Product: plasmashell
Version: 6.2.4
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Power management & brightness
Assignee: plasma-b...@kde.org
Reporter: 0456...@gmail.com
Target Milestone: 1.0
SUMMARY
When pressing the brightness up or down keys, the brightness changes by 10%
instead of 5% most of the time.
Sometimes, it changes by 5% but there doesn't seem to be a pattern to when it
decides to correctly change by 5 instead of incorrectly changing by 10.
Changing the shortcut to something without the brightness keys (like
Meta+Shift+U or Meta+Shift+D) will not exhibit this behavior.
Any shortcut that *does* use the brightness keys (like Ctrl+Monitor Brightness
Up or Ctrl+Monitor Brightness Down) *will* exhibit this behavior.
STEPS TO REPRODUCE
1. Press the brightness up or brightness down key
OBSERVED RESULT
The OSD will pop up and indicate a change of 10% instead of 5% most of the
time. Sometimes it correctly changes by 5 but that seems to happen randomly.
EXPECTED RESULT
The brightness should consistently change by 5%.

Linux: Arch Linux x86_64, Kernel 6.12.4-arch1-1
