Package: powerdevil Version: 4:6.3.6-2 Severity: important X-Debbugs-Cc: [email protected]
Dear Maintainer, After an update of various kde-plasma related packages on Debian testing (Forky) this morning 2025-10-25, the plasma-shell service was unable to load the KDE system tray. Instead of the usual system tray icons, there was only a single one displaying the message: "Error loading Applet: package does not exist." I checked for service loading failures with systemctl: every service seems to run normal. Upon further investigation in journalctl, I found the following powerdevil errors. When restarting the powerdevel service, I get the following messages: org_kde_powerdevil[9145]: [ 9145] Error(s) opening ddc devices org_kde_powerdevil[9145]: Error EACCES(-13): Permission denied opening /dev/i2c-12 org_kde_powerdevil[9145]: Error EACCES(-13): Permission denied opening /dev/i2c-13 org_kde_powerdevil[9145]: Error EACCES(-13): Permission denied opening /dev/i2c-14 org_kde_powerdevil[9145]: Error EACCES(-13): Permission denied opening /dev/i2c-15 org_kde_powerdevil[9145]: Error EACCES(-13): Permission denied opening /dev/i2c-16 org_kde_powerdevil[9145]: Error EACCES(-13): Permission denied opening /dev/i2c-17 org_kde_powerdevil[9145]: Error EACCES(-13): Permission denied opening /dev/i2c-18 org_kde_powerdevil[9145]: Error EACCES(-13): Permission denied opening /dev/i2c-19 org_kde_powerdevil[9145]: Error EACCES(-13): Permission denied opening /dev/i2c-20 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-7 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-8 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-9 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-10 org_kde_powerdevil[9145]: [ 9166] (dw_recheck_displays_func) Recheck interval: Sleeping for 200 milliseconds org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-11 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-12 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-13 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-14 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-15 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-16 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-17 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-18 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-19 org_kde_powerdevil[9145]: [ 9145] Error EACCES(-13): Permission denied opening /dev/i2c-20 org_kde_powerdevil[9145]: org.kde.powerdevil: org.kde.powerdevil.chargethresholdhelper.getthreshold failed "Charge thresholds are not supported by the kernel for this hardware" org_kde_powerdevil[9145]: org.kde.powerdevil: org.kde.powerdevil.backlighthelper.brightness failed systemd[4359]: Started plasma-powerdevil.service - Powerdevil. org_kde_powerdevil[9145]: org.kde.powerdevil: Handle button events action could not check for screen configuration org_kde_powerdevil[9145]: org.kde.powerdevil: org.kde.powerdevil.chargethresholdhelper.getthreshold failed "Charge thresholds are not supported by the kernel for this hardware" Note, I use a desktop PC, so I guess the charge threshold helper failures are expected. While starting this bug report there was a message prompted, informing me that my powerdevil powerdevil package is outdated. Not sure how this is related to the issue. However, I doublechecked and my package manager is using the forky repositories. I am uncertain if these powerdevil errors are at all related to the system tray problems, therefore I will file a separate bug report on that matter. Also I am uncertain, if these erros can be ignored.
