How do I install KDE?
You need to install the kubuntu-desktop
package for the full install.
The GUI method would be to click this button:
(source: hostmar.co)
The command line method would be:
sudo apt-get install kubuntu-desktop
Then the next time you login you can choose what to use from the login screen (under Session).
To get just the plasma environment (on 12.04 and newer):
sudo apt-get install plasma-desktop
It worked fine for me on 15.10
If you want to log in from KDE run sudo apt-get install kdm
, sudu apt-get remove gdm
, and dpkg reconfigure kdm
.
