I use the KDE desktop. I came in this morning and noticed screen was unlocked. I tried to check system settings but it was missing. I did the weekly update yesterday so maybe something got uninstalled that shouldn't have been. So I installed systemsettings and opened it, but many settings categories are missing.

This install is 2 months old. I am looking at doing a complete reinstall in case unknown things related to security and stability are also missing. Anyone else have this issue?
