Re: Tumbleweed: lm-sensors installed and working, but fanspeed plasma object and other sensor object do not work

Hello, Your experience sounds a lot like what I have gone through recently. I bought a new computer (this tale has been on this list), installed Leap 15.3 (not Tumbleweed) booted it up, and it worked...for a few minutes, between 5 and 15...and then screen went black and the power supply, and case fans started spinning at 100%--totally hung, only way out was pulling the power cord. Nothing I tried could resolve the issue....I thought it was a driver issue with the nvidia graphics card, but that lead nowhere. So, I bought a 3-year old used computer (happily I can disable the UEFI stuff on this one...UEFI can not be disabled on the new one.), installed 15.3 and it is stable and happy. I would love to get the new computer working with Leap, so if you resolve your problem, please share your solution. It may help, or (of course) it may not.

Many thanks, Mark On 03/22/2022 8:27 AM Stakanov wrote:

lm-sensors and the setup including the new directory is installed and working. I had to reinstall my TW, before all worked error free. But now, no plasmoid seems to "see" the sensors. When I however go to CLI and do as normal user:

Three fans as expected (cpu and 2 PWR system ones) All sensors are there, but none is seen. Could this be a permissions issue? Any hint why the plasmoids do not have access to the existing values of lm- sensors? I have also reinstalled all sensor related plasmoid from the web again, but nothing, included reboot.

Thankful for some clue about this. Again: ANY sensor is seen of the above in plasma. I do not think the problems are directly related but I can give you some hints on work around the issue.

I do not think that UEFI is the culprit here but more the energy saving settings of the BIOS. Try to first deactivate all Energy Saving features to see if the situation improves. See also and make sure that on the new machine you have IOMMU activated. Report back if the situation improves like that. If it does, then you could try to see if one by one you find the feature causing the issue. The fact that the "screen goes black after some time" is often a energy saving issue. If you are are using plasma, this could be simply a crash of the plasma surface and the workaround is: open at the beginning of the session yakuake. Make it scroll down when you touch the upper screen. (sudo zypper in yakuake) then go to settings for the scroll effect. When the screen goes black and you use plasma chances are good you are running into a mesa problem. In this case, try to: open yakuake as a normal user write: kstart5 plasmashell and return. This should restart the plasma desktop and the "black screen" should turn to normal.
