SUMMARY After reboot, lm-sensor readings, such as CPU temperatures, are displayed as OFF. At the same time, the "sensors" command displays temperatures as expected. STEPS TO REPRODUCE 1. Add Thermal Monitor widget on the horizontal panel. 2. In the widget options, add lm-sensor sources, lmsensors/coretemp-isa-0000/Package_id_0, lmsensors/coretemp-isa-0000/Core_0, etc. 3. Reboot. OBSERVED RESULT After reboot, the added sensors are displayed as OFF. The "sensors" command show expected temperatures. Sometimes, if I open the widget options, change one of the sensors to something else, then change back, and click Apply, the sensors start displaying valid readings. EXPECTED RESULT Sensor readings should be displayed correctly. SOFTWARE/OS VERSIONS Linux/: Kubuntu 19.04 KDE Plasma Version: 5.15.4 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.2
We don't have a thermal monitor widget. Can you confirm the name please.
The name is "Thermal Monitor", and apparently it's not a built-in widget of Plasma and it was installed from elsewhere, probably from here: https://store.kde.org/p/998915. Sorry for the confusion.
