The fault is as reported by rullger at https://forum.kde.org/viewtopic.php?f=67&t=156749&p=410152&hilit=thermal#p410152 during beta testing.

I am using PCLinuxOS on AMD FX 8350 on GA-970A-DS3P (Rev 2.0), 8GB RAM, Asus EN210 (Nvidia) GPU, Maxtor STM325031, 3 SSDs, Amilo LSL 3220T monitor.

I had thought if I could identify the process I might be able to send it a SIGHUP to reload the sensors as a workaround, but I can't identify the process for the applet or find out where it is installed. Can anyone help, please?

It's very annoying when things that used to work stop working and I'd really like to get this going without needing manual intervention at every system start.

Yes.

Try any of the methods mentioned here. They are all mutually exclusive, so just use either one of them. I tried all three of them, one at a time of course, and I could confirm that they all fixed the issue. I ended up settling with the first method however, since I was trying them from last to first, kek.

That comment mentioned to edit the file at

Code: Select all

/usr/share/plasma/plasmoids/org.kde.thermalMonitor/contents/ui/main.qml

but depending on how you install the plasmoid, the file that you may need to edit can be located here instead

Code: Select all

~/.local/share/plasma/plasmoids/org.kde.thermalMonitor/contents/ui/main.qml

At least that was the case for me since I installed the plasmoid from Plasma's Download New Widgets menu.

Here is Guide How to check what is average Maximum & Normal CPU temperatures.

I can confirm this worked for me on Kubuntu v19.10 and now v20.04 - after a restart it shows OFF but as soon as the monitor pokes the sensors it fires up. OFF is only shown for one or two pokes so by the time you're ready to open a program, it's already started to show you the temp. This was with a clean install of v20.04 and simply add the Thermal Monitor widget > click Get New Widgets... > Click Download New Plasma Widgets > search for Thermal Monitor > click Install > go back to the widgets lists and drag the monitor widget to your desktop and configure as normal, then edit the properties:

Open a terminal window and enter:
sudo nano ~/.local/share/plasma/plasmoids/org.kde.thermalMonitor/contents/ui/main.qml

Scroll down a few pages to find and change this property:

property var systemmonitorAvailableSources
Add a colon, space, open/close brackets like so:
property var systemmonitorAvailableSources: []

CTRL O to save, CTRL X to exit, close the terminal window and reboot. Your monitor should now work.
