Description of problem:

After latest Cauldron updates to Plasma 5.22 it seems the Plasma System Monitor and associated widgets are broken - don't show data (see attached screenshot)

No specific error - just no data

Comment 5 Robert Fox 2021-08-04 10:27:23 CEST

Turns out it's both plasma-systemmonitor and systemmonitor that seems to have the issue - here, I started them from the command line:

[rfox@FoxLT5 ~]$ plasma-systemmonitor 
org.kde.ksysguard.plugin.network: Helper process terminated abnormally!
org.kde.ksysguard.plugin.network: "The process doesn't have permission to open the capture source\n"
^C
[rfox@FoxLT5 ~]$ systemmonitor   
org.kde.ksysguard.plugin.network: Helper process terminated abnormally!
org.kde.ksysguard.plugin.network: "The process doesn't have permission to open the capture source\n"
QProcess: Destroyed while process ("/usr/bin/nvidia-smi") is still running.

Comment 8 papoteur 2022-10-07 08:55:41 CEST

Nicolas, you don't have the same output. In particular, you haven't any error about openGL.
I found that the package lacks ksystemstats requires.

Comment 9 papoteur 2022-10-08 09:17:25 CEST

The package now requires ksystemstats.
However, I don't know about openGL errors.
Yuusha, if you have them without damage, or anymore, can you close this report?

Comment 10 Cyril Levet 2022-10-08 09:49:28 CEST

It works now.

OpenGL errors are still here, but does not prevent the program from working. Maybe, there are VirtualBox related.

Comment 11 papoteur 2022-10-08 10:49:55 CEST

Thus closing.
Thanks
