SUMMARY I have a static connection on eth0. I don't use NetworkManager. It's not running. Network monitor stopped working after upgrade to Frameworks 5.88. Re-installing networkmanager-qt 5.87 package solves the issue. OBSERVED RESULT System monitor plasmoid configuration doesn't show network devices. In plasma-systemmonitor, "Networks" and "Network rates" areas show nothing. EXPECTED RESULT Like with with networkmanager-qt 5.87 : System monitor plasmoid configuration shows eth0. In plasma-systemmonitor, "Networks" and "Network rates" areas show eth0. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Slackware 15.0 RC2 KDE Plasma Version: 5.23.3 KDE Frameworks Version: 5.88.0 Qt Version: 5.15.3 (20211024_2aa0de43) ADDITIONAL INFORMATION
I found the problem was caused by a new runtime dependency on NetworkManager which wasn't installed. Same thing with ksystemstats 5.23.4. No more problem after NetworkManager installation. Maybe platform specific. For what I have to say, it's resolved. Updating status and title, and adding ksystemstats developper for info.
