I have Ubuntu 16.04 Xenial Xerus and I installed kubuntu-desktop.

sudo apt-get install kubuntu-desktop

Now there is no KDE in the login screen selection. Just Gnome classic, Gnome-wayland (which does not work because 15.081410 rc.local[1923]: Error opening display!) MATE (the only one usable) Plasma (black desktop with a few tray icons and no usable panels...)

How do I make KDE appear there as well?

BTW How the heck do I make my post preserve all line breaks and not just some? This is not very readable. I am sorry, but I did not figure out how to fix that...

    Plasma is the kubuntu-desktop. – user589808 Oct 4 '16 at 15:22
  • Aha :D The thing is that I tried to install it a long time ago. It did not work and I forgot meanwhile. Any idea how to fix it? As I said - black background, few scattered tray icons in the middle and nothing else... It's been some time and I thought they might have fixed it already. – Vitas Oct 5 '16 at 6:17
  • Sorry, I don't know. I never installed it as an additional DE. I do use a few KDE apps though (and its dependencies). Perhaps reinstalling the meta-package (with --reinstall) will bring something that's missing. – user589808 Oct 5 '16 at 9:22
  • Which meta-package you mean? Kubuntu-desktop? – Vitas Oct 5 '16 at 20:35
  • Yes, of course. It's a meta-package because it has no content in itself but lists and installs others. – user589808 Oct 5 '16 at 20:43

In order to assure the correct and complete installation of all the packages required, use the following command to reinstall the kubuntu-desktop meta-package:

sudo apt install --reinstall kubuntu-desktop
