Question: I am a new user of Linux. I just installed Ubuntu and now I want to try the KDE desktop environment. Can you guide me how to set up KDE in Ubuntu?

Answer: 
To install the KDE Desktop, go to the terminal and type in this command:

```
sudo apt-get install kubuntu-desktop

```

This will install the KDE desktop environment on Ubuntu. Reboot, then select the KDE desktop at the login screen (it will look like something similar to this):

Enjoy!
You should try Kubuntu for best experience. Kubuntu is optimized for KDE, Ubuntu is optimized for Unity. Installing KDE in Ubuntu will not optimize it in any way.
