How do I install KDE?

Question

I want to have both KDE and Gnome shells on Ubuntu. Ubuntu only has Gnome installed by default. How do I install KDE?

Answer 1

You need to install the kubuntu-desktop package for the full install.

The GUI method would be to click this button:

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).

Answer 2

If you want to log in from KDE run sudo apt-get install kdm, sudu apt-get remove gdm, and dpkg reconfigure kdm.

Answer 3

Just try the following command in a terminal

sudo apt-get install kubuntu-desktop

Then just select KDE on the login manager.

To get just the plasma environment (on 12.04 and newer):
