Using KDE Plasma.

When I try to login, I see all my previously opened windows and my background (no icons, not hotbar). Sometimes the icons pop up for a second, then background goes black. No hotkeys apart from Ctrl+Alt+Delete seem to work.

Created a new user in terminal, cannot login (back to login screen).

I don't think I changed anything, just happened after a reboot.

As I do not have a working internet connection (NetworkManager doesn't seem to start without KDE), I cannot reinstall xorg and kde.

System was originally Kubuntu 17.10, upgraded to 18.04

Update

Managed to connect to WiFi using nmcli.

Purging kubuntu-desktop kde-* *plasma*, then installing only plasma-desktop fixed it, but several features are missing. Installing kubuntu-desktop gets me back to where I was before (no bars, no background)

Fixed it by purging all kde and plasma packages (see update) then installing in batches. Managed to narrow it down to print-manager.

Apparently a faulty printer installation can cause plasma to crash.
