            Bug ID: 501415
           Summary: Brightness level below 100% is not persistent after
                    reboot or unplugging/replugging power adapter
    Classification: Plasma
           Product: plasmashell
           Version: 6.3.2
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: Power management & brightness
          Assignee: plasma-b...@kde.org
          Reporter: johnebedf...@gmail.com
  Target Milestone: 1.0

SUMMARY
I set my laptop screen brightness to around 30%. However, since a recent update
(I think to Plasma 6.3) this setting is no longer persistent after (1) a reboot
or (2) unplugging then replugging the power adapter. In these cases it resets
to 100%. NB on suspend/return the brightness level is indeed persistent.

STEPS TO REPRODUCE
1. Set brightness to level below 100%
2. Either (1) reboot or (2) unplug and replug the power adapter

OBSERVED RESULT
Brightness level resets to 100%

EXPECTED RESULT
Preset brightness level (below 100%) is maintained
