I followed the steps, but after the installation was done, the system hanged. I forced shut it down and on restart, although kubuntu logo showed up, but still Ubuntu is loading with GNOME only. I have restarted multiple times but no luck.

DO NOT USE tasksel to remove it afterwards. It will remove half of your system alongside totally breaking the OS


I tried to install Plasma desktop to Ubuntu 16.10 and obliterated it. I have run KDE Neon since Ubuntu discontinued Unity. Can’t get much satisfaction out on Gnome. Neon is easy to install and easy to use. Very stable. Recommend if you want to try Plasma that you take the Neon route.


A post was split to a new topic: Logout and login - there is no options to choose KDE
