After removing KDE an On-screen Keyboard Obstructs the Login Screen

Support & Help Requests
1

I manually removed KDE Plasma from my system with Synaptic (though I did leave quite a few packages installed to retain the dependencies for other KDE software). After this, however, upon startup and whenever the login screen is displayed (not the lock-screen) a large, black on-screen keyboard obstructs the login screen. I can hide this with the downward facing arrow button in the bottom right of this keyboards interface. There is also a drawing/calligraphy tool feature in this keyboard (I’m not sure what package/software it is).

Can someone help me remove this, and cleanly remove the rest of KDE? I’ll just reinstall the desired KDE software afterwards and let the package manager handle dependencies, as I should.

Appendum: I’ve entirely removed KDE from my system (except for the Breeze mouse-cursor theme; it has no dependencies) with Synaptic, and now I have no login screen. Upon boot, I have a terminal on TTY1 (with the text slightly bolder than other virtual terminals (TTY2-6; there is no TTY7) and I must login manually and then start the MATE DE with ‘startx’.

I’d like to revert my system to a default installation of MATE, but without having to go through a backup and installation process. How can I revert back to a default configuration?

Hello

You do not say if you are using Ubuntu-Mate or not.

Over years of reading on the internet I have pieced together the following "theory": If you are running a Debian system you can add, delete and change desktop environments with a high degree of success. If, however, your base system is Ubuntu, you will find this is not as successful.

I have a very limited personal experience which seems to back this up, but I'm not an expert on the matter. If using "Ubuntu-something" I would recommend installing the flavour which has the desktop environment that you want and then sticking with that. :slightly_smiling_face:
