Since upgrading to Plasma 5.9.0 (openSUSE Tumbleweed), Ksysguard seems to have broken in several ways: The menubar is completely gone, whereas the "CPU History" and "Network History" displays are completely empty! Anyone else experiencing those issues and knows what might be wrong?

Menubar issue solved: For some reason I had MenuBar=Disabled in ~/.config/ksysguardrc, and of course removing it made the menubar appear again.

The CPU and Network histories are however still empty, even with a fresh ksysguardrc file! Could it be an openSUSE Tumbleweed specific issue, or the update introducing something that doesn't like my hardware?

Hi
Same problem for me, however I'm on Kubuntu 16.04.

ksysguard 5.5.5
KDE Frameworks 5.18.0
Qt 5.5.1 (built against 5.5.1)

It's been a while I've noticed this issue... Maybe 3 months

I also have this cpu and network graph issue for some time.
I'm on a fully patched Arch installation (from 2015).

On my work laptop I recently installed a base Antergos and then manually installed Plasma5 and I don't have any issues.

Back to troubleshoot.

[EDIT - SOLVED] As mentioned on https://bugs.kde.org/show_bug.cgi?id=218796#c18 , copying /usr/share/ksysguard/SystemLoad2.sgrd to ~/.local/share/ksysguard/SystemLoad2.sgrd solved the issue.
Removing ~/.config/ksysguardrc in my case wasn't necessary.
