Hey,
after the recent KDE 4.14.3 update I'm missing sensors in my "Sensor Browser" in System Monitor:


However I still have them in the system:

Code: Select all

How can I add these to the Sensor Browser?

what *sensor* packages do you have installed?

guessing (as not a *buntu person) you might be missing libqtsensors4

I (again as not a *buntu person) guess you'd need the following packages: libsensors4, libqtsensors4, lm-sensors and sensord

Yes, I have all the appropriate sensor packages installed here. Also as you can see in the screenshot some sensors are already available. But I'm missing some, specifically fan 1,3,5 and temps.

2 possibilites:
1) there's an issue with one of your account's ksysguard related files if so rename ~/share/.kde/config/ksysguardrc and ~/.kde/share/apps/ksysguard/, you can also test this as a new user

2) something needed by ksysguard isn't installed or wasn't installed correctly if so then reinstall all relevant packages listed on this page, minimally ksysguard, libksgrd4 and libqtsensors4

Ok, I checked 1) and 2) no difference so far...

But may I ask you, if you do this:
1. Run sensors-detect in terminal (requires root)
2. run sensors
3. note that list
4. start ksysguard (System Monitor)
5. File -> New Tab
6. Check the Sensor Browser, every sensor reported by "sensors" should be available in that list!

Then you see all sensors from "sensors" in the "Sensor Browser"?

sensors only detects temps on my motherboard and they show in ksysguard

did you try as root ?

close ksysguard, then run kdebudialog -> deselect all -> search for ksysguard -> check ksysguard -> ok, then start ksysguard and look at the tail end of ~/.xsession-errors - anything sensors related show?

Which version did you update from? There have not been any changes in KSysGuard in a long time - so it is probable that another change elsewhere caused the issue.

@google01103:
You mean ksysguard as root?
I just tried no change, also no entries in xsession-errors

@bcooksely:
I updated from 4.13 and yeah I already thought so, too. I posted now on my distro forum too, if they have the same error...

Can you please use kdebugdialog to enable debug output? Then try to start ksysguard from the terminal again.

Hi Ben,
sorry for delay.

Yes, this is the output from terminal:
