I don't know if this is a packaging bug in Ubuntu, if so, please simply mark it as invalid: When you deinstall kdm, systemsettings still shows the kcm_kdm module as icon, and if you click on it, you see an error, that the kcm_kdm module can't be found. Reproducible: Always Steps to Reproduce: 1. deinstall kdm 2. open systemsettings Actual Results: the kdm icon is still there and leads to an error page Expected Results: I would expect that the icon is gone as nothing refers to it any more. It should be part of the kdm package (which maybe is just a packaging issue?)
Does running "kbuildsycoca4 --noincremental" between removing kdm and starting System Settings help?

Yes, perfectly. after running "kbuildsycoca4 --noincremental" the kdm entry is gone. So where is the problem? Is this a packaging bug - there seems to be this command missing in the postrm script of apt in (K)ubuntu (what I'm using)? Normally after removing a kde component that has a link in systemsettings there should be run this command, right? Should I report it in Launchpad/Ubuntu?
> So where is the problem? I have no idea. Normally, I would expect that removing files from the service directories would trigger an sycoca refresh, but it could also be a bug in System Settings itself. Reassigning.
How can I help?
kded4 is responsible for firing the kbuildsycoca4 process off. System Settings will need to be restarted however for old modules to disappear.
KDM no longer exists in Plasma 5
