The KDE community has officially announced the release of KDE 4.1. This second feature release of the KDE4 contains many bug fixes, added more applications and also polished up the Plasma desktop to make it even more stunning. On the same day, the Ubuntu team has also released a package for its users to upgrade to the new KDE 4.1. Ubuntu GNOME users can also install KDE4.1 and run alongside their GNOME desktop.

Installing KDE 4.1 in Ubuntu Hardy Heron
In your terminal,
gksu gedit /etc/apt/sources.list
Add the following line to the end of the file
deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu hardy main
Save and close the file
sudo apt-get update
sudo apt-get install kubuntu-kde4-desktop
This will download a whole bunch of KDE files.
Once it is done, reboot your computer. You will now see a change in the boot screen. The usual Ubuntu usplash screen is now changed to Kubuntu usplash.
You will also see a new login window.
Click on the Session Type and select KDE 4
You should now see the KDE desktop with the Oxygen theme.
Move your mouse to the top right corner to add widgets to the desktop.
And the bottom right corner to add icon to the bottom panel
Overall, I like KDE 4.1 very much. The Plasma desktop is much more polished now and the new applications such as KDE-PIM integrates well with it. While GNOME gives you the flexibility to customize your desktop, KDE 4.1 gives you the stunning interface right from the start. Good work! KDE.
