Bug ID: 473562
Summary: Screen is dimmed after an arbitrary amount of time
Classification: Plasma
Product: Powerdevil
Version: 5.27.7
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: hi-an...@yandex.ru
CC: m...@ratijas.tk, natalie_clar...@yahoo.de
Target Milestone: ---
SUMMARY
Disregarding the value I have set in `System Settings → Energy Saving → Dim
screen` (which is currently set to 8 minutes) the screen always gets dimmed
much earlier. I just measured and it is 4 minutes.
Workaround: `systemctl --user start plasma-powerdevil`, unfortunately that way
you lose control over your brightness settings. So ATM is repeatedly switch
stop and start the service as I work which is very annoying.
STEPS TO REPRODUCE
1. Go to `System Settings → Energy Saving`
2. On every available tab set `Dim screen` timeout to 8 minutes.
3. Wait for 4 minutes
OBSERVED RESULT
Screen gets dimmed
EXPECTED RESULT
Screen has light as usual

ADDITIONAL INFORMATION
I'm not sure if it's relevant, but when I restart `plasma-powerdevil`, I get
these lines in the log:
org.kde.powerdevil: Handle button events action could not check for screen
configuration
org.kde.powerdevil: org.kde.powerdevil.chargethresholdhelper.getthreshold
failed "Charge thresholds are not supported by the kernel for this hardware"
