I have just installed the latest Ubuntu 14.04 and I would like to install KDE along side my Gnome/Unity that I have now. How can I do this?


  • To get kde you can install the kubuntu-desktop package for full kde and other pre installed software on kubuntu. Apr 21, 2014 at 13:28
  • If you want the full kubuntu experience as well, you can even install the kubuntu-full package. Apr 25, 2016 at 15:02

You can install kde 4.12 easily on ubuntu 14.04 , open terminal :

sudo apt-get update
sudo apt-get install kubuntu-desktop

Enjoy using KDE

  • Just a note, you may need to install software-properties-kde first. I couldn't install kubuntu-desktop until I installed software-properties-kde.

    Just a note: save startkde to .xsession to connect from Windows' remote desktop.

    This no longer works because of this bug: bugs.launchpad.net/ubuntu/+source/mesa/+bug/1424263

  • Ubuntu 18.04.2 LTS, just sudo apt install kubuntu-desktop is enough to switch to KDE/Kubuntu. Mar 26, 2019 at 13:25

Good answers here, but when installing you'll be asked a question in a terminal about choosing between lightdm and kdm. Either works well and lightdm should be selected by default, just press [ENTER}.

Reboot/logout, and when you go to login again, you'll see a "gear" icon next to your password window. Click it and select KDE, now enter your password.

This option will be remembered until you decide to change.

  • How can you change it back if you selected sddm by mistake?

    This question is old, but I wanted to add that as of October 2016, the KDE developers recommend SDDM over LightDM due to better Wayland support. To answer your question: sudo dpkg-reconfigure lightdm Oct 28, 2016 at 7:19
