Hi there, need some help here- kde systemsettings won't load any module , seems the kcm modules they are all missing for some reason may be the last update. This happens on neon unstable .

Exactly the same here - would really like to get this fixed.

I am on opensuse leap 15.1 with kde (or is it plasma?) 5.18.90

Also noticed that on startup I can now choose between plasma, plasma (wayland) and plasma (full wayland). I have no clue what these differences mean and whether they have anything to do with my systemsettings problem.

I'm on neon unstabel kde 5.19.80 not using wayland, as it is a display server i suppose it's not related to the latest problem with kde system stettings. After several updates ran on my system still no fix for the issue, beside this everything works without remarks.

It now seems to me that the problem was caused either by some hickup in the update process or by wayland, or both.

I have now reinstalled the original plasma version (5.12...), everything worked there, and then upgraded again to 5.18, but without choosing neither "wayland" nor "full wayland" (no matter what the difference is, remains still a mystery why stuff like that is installed on my computer and nobody can tell me what it is) as login option.

Now everything SEEMS to work properly.

Nice, glad to hear that! There was an update on neon unstable last hour that fixed the problem here, now everything's fine as it has to be!
