As you already know, Linux Mint 15 Olivia has just been released, a few days ago. Because it comes, by default, only with Mate and Cinnamon, users may want to change its desktop environment.
But don’t you worry. If you are a KDE fan, you can install it easily on your new Linux Mint. In this article I will show you how to install KDE on Linux Mint 15 Olivia.
There are different KDE versions available, for KDE standard do:
$ sudo apt-get install kde-standard
For the full version, install the kde-full package:
