Bug ID: 472165
Summary: KDE Power Management System init failed with
powerdevil 5.27.6 on Steam Deck
Classification: Plasma
Product: Powerdevil
Version: 5.27.6
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: dominik.kra...@gmx.net
CC: m...@ratijas.tk, natalie_clar...@yahoo.de
Target Milestone: ---
After upgrade powerdevil from 5.27.5-3 to 5.27.6-1, 5.27.6-2 or 5.27.6-3
powerdevil failed to start on Valve's Steam Deck.
If I start powerdevil from terminal I get these error messages:
org.kde.powerdevil: KDE Power Management System init failed!
org.kde.powerdevil: org.kde.powerdevil.chargethresholdhelper.getthreshold
failed "Charge thresholds are not supported by the kernel for this hardware"
With version 5.27.5-3 everything works fine. However there was the hint "Charge
thresholds are not supported by the kernel for this hardware" too. But
powerdevil starts and I am able to see the battery and brightness widget an set
the standby timings in the KDE settings, which is not possible with powerdevil
5.27.6-1, 5.27.6-2 or 5.27.6-3.
STEPS TO REPRODUCE
1. Install powerdevil >= 5.27.6-1 on the Steam Deck
2. Start KDE
3. Go into the energy settings or try to use the battery and brightness widget.
OBSERVED RESULT
If you open the energy settings in KDE, it tells me that powerdevil couldn't be
started.
The battery and brightness widget isn't shown.
EXPECTED RESULT
Energy settings in KDE are shown without errors.
The battery and brightness widget appears.
