Install KDE 4.1 in Ubuntu/Kubuntu

KDE 4.1 was released to address many of the issues and complaints people had against KDE 4 and it completely lives upto its expectations.From better application integration to the many new desktop effects similar to compiz fusion are added in this version. Beware though KDE 4.1 is still in beta stage so I would suggest you back up all your data before installing it.

First you need to edit your sources list to add the KDE 4.1 repository, to do that simply enter this command into the terminal

sudo gedit /etc/apt/sources.list

this will open up Gedit and will list all your repositories at the end just add this line

deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu hardy main

This is the KDE 4.1 repository now save the file and exit gedit, Ubuntu now needs to read the packages from the newly added repository to do that simply enter this into the terminal

sudo apt-get update

Now to install KDE 4.1 if you are using Ubuntu execute this command

sudo apt-get install kubuntu-kde4-desktop

If you are using Kubuntu execute this command

sudo apt-get dist-upgrade

And now just restart your computer then when asked to enter your user name and password in sessions select KDE 4 as the default desktop environment so that the next time you start you wont have to select KDE 4 again and again
