I updated to KDE Plasma 5.22.3 today. After this update I have problems with System Monitor, specifically with the CPU temperature sensor.
I had a graph with the CPU temperature added to History page in System Monitor. After the update, the data stopped coming into the graph and the sensor that was used is no longer in the list of available sensors. Now I can only display the temperatures of a specific processor core, but not the entire processor.
In KSysGuard this sensor is available and working:
Hardware Sensors → coretemp-isa-0000 → Package_id_0
Please read this: How to provide good information
and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…
An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.
What’s the output to:
P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you’re using, which CPU/GPU or Kernel, … you have without typing it every time
I tried to start with Linux 5.10.49-1 LTS, the problem remained.
I assume that in the new version of Plasma, some change was made in the principle of creating sensor groups for System Monitor, but so far I have not been able to find the specific code/configuration responsible for this.
