Bug ID: 476369
Summary: Power Devil Restart Loop
Classification: Plasma
Product: Powerdevil
Version: 5.27.9
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: theatt...@gmail.com
CC: m...@ratijas.tk, natalie_clar...@yahoo.de
Target Milestone: ---
SUMMARY
***
Powerdevil updated to 5.27.9-2 with ddcutil to 2.0.0-1. Update was 2 days ago.
The Power module is broken every since. Using journalctl I got the following
for you.
"org.kde.powerdevil: org.kde.powerdevil.chargethresholdhelper.getthreshold
failed “Charge thresholds are not supported by the kernel for this hardware”
Oct 30 10:51:46 attish-archLinux org_kde_powerdevil[3705]: org.kde.powerdevil:
org.kde.powerdevil.backlighthelper.brightness failed
Oct 30 10:51:51 attish-archLinux systemd[901]: plasma-powerdevil.service: start
operation timed out. Terminating.
Oct 30 10:51:51 attish-archLinux systemd[901]: plasma-powerdevil.service:
Failed with result ‘timeout’.
Oct 30 10:51:51 attish-archLinux systemd[901]: plasma-powerdevil.service:
Consumed 1.745s CPU time.
Oct 30 10:51:51 attish-archLinux systemd[901]: plasma-powerdevil.service:
Scheduled restart job, restart counter is at 46."
This restart loop never ends. Downgrading to previous versions work. After
downgrade, this is what pacman spits out after using pacman -Syu so you know
which version I am using currently.
warning: ddcutil: ignoring package upgrade (1.4.1-1 => 2.0.0-1)
warning: powerdevil: ignoring package upgrade (5.27.8-2 => 5.27.9-2)

STEPS TO REPRODUCE
1. Upgrade ddcutil and powerdevil to the versions that I have stated above.
OBSERVED RESULT
The power devil service always crashes and tries to restart itself and whenever
it does, it freezes the computer for a second. Restart loop causes this every 5
or so seconds.
EXPECTED RESULT
The power devil module and service should work fine after update and the power
module should be loaded in System Settings
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma:
(available in About System)
KDE Plasma Version: 5.27.9
KDE Frameworks Version: 5.111.0
Qt Version: 5.15.11
ADDITIONAL INFORMATION
In order to make it work I have to use the following commands:
killall org_kde_powerdevil
kstart5 /usr/lib/org_kde_powerdevil
It spits out:
org.kde.powerdevil: org.kde.powerdevil.chargethresholdhelper.getthreshold
failed “Charge thresholds are not supported by the kernel for this hardware”
org.kde.powerdevil: org.kde.powerdevil.backlighthelper.brightness failed
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”
The restart loop breaks this way.
