Bug ID: 494497
Summary: Screen brightness is being changed even though "change
screen brightness" is disabled.
Classification: Plasma
Product: Powerdevil
Version: 6.2.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

SUMMARY
Powerdevil is controlling screen brightness even though it's disabled. When I
first logged in after upgrading to Plasma 6.2 both my monitors popped up the
Dell "Adjusting this value will increase power consumption above the default
level" but didn't actually successfully change the brightness because it wanted
me to confirm. I double checked that the setting was disabled and it was, but
the greyed out slider said "70", which is lower than the percent threshold to
trigger that warning on my monitor, so it seems to be defaulting to 75+
internally even though the UI said 70.
I enabled the setting and tried a couple values and then turning off "change
screen brightness" and it changed the brightness to the value every single time
after rebooting and adjusting the brightness manually.
STEPS TO REPRODUCE
1. Turn off "Change screen brightness" in Energy Saving
2. Manually adjust screen brightness to a different value.
3. login/logout
OBSERVED RESULT
Screen brightness changes.
EXPECTED RESULT
No changes.
