For Ubuntu Gutsy users who wants to try out KDE 4, you can install KDE 4.0 side by side with GNOME.

First, add the KDE repository to the sources.list.

Open up a terminal (Applications -> Accessories -> Terminal). Type

sudo gedit /etc/apt/sources.list

Add the following line to the end of the file and save it.

deb gutsy main

Back in the terminal, type,

sudo apt-get update

Alternatively, if you don’t like command line interface, you can add the repository through the Synaptic Package Manager.

Open up your Synaptic Package Manager (System -> Administration -> Synaptic Package Manager).

Go to Settings -> Repositories. Click on the Third-Party Software tab.

Click Add, and paste the above repository to the field.


Now click the Add Source. Immediately, it will ask you to reload information about the new package. Click Reload.

If you have installed any previous version of KDE4.0, you have to remove it first.

In your terminal,

sudo apt-get autoremove kdelibs5 kde4base-data kde4libs-data

Once done, type

sudo apt-get install kde4-core

It will now retrieve over 100MB of file, so you might want to go for a coffee break.

After downloading and installation has finished, log out of the GNOME desktop. Under the Session, choose KDE 4. Login. You should have the KDE 4 working in your desktop now.


(PS: The latest release is KDE 4.0.1 contains numerous bugfixes, performance improvements and translation updates.)
