Most Linux distributions have a "main" desktop environment they use - the one that comes installed by default in the distro's most popular download. For Kali Linux, it's Xfce.

If you prefer KDE Plasma over Xfce or are just looking for a change of scenery, it's quite simple to switch desktop environments on Kali. In this guide, we'll walk you through the steps to install the KDE desktop environment on Kali Linux.

Install KDE Plasma Desktop Environment

Follow the step by step instructions to install KDE and learn how to switch between Xfce and KDE desktop environments once both are installed. We'll also see how to remove Xfce completely, in case you want to make a permanent switch to KDE or encounter conflicts from having both environments installed simultaneously.

  1. Open a terminal and type the following commands to install KDE.
    $ sudo apt update
    $ sudo apt install kali-desktop-kde

  3. If you receive a notification that asks you what display manager to use, select sddm, as that is the display manager for KDE.

    Select sddm display manager and press Enter
    Select sddm display manager and press Enter
  4. Installation may take some time, as many packages and their dependencies will have to be downloaded and installed. But once installation has completed, reboot the computer.
    $ reboot
    
  5. When Kali finishes loading back up, you'll be presented with the option to select KDE or Xfce from the login screen (note that you must first select your user).

    Select Plasma or Xfce, depending on which environment you want to use
    Select Plasma or Xfce, depending on which environment you want to use


  6. If you like KDE so much that you want to get rid of Xfce completely, which will get rid of the option to select it from the login screen, execute the following commands in terminal. The second command will remove any lingering packages that were part of Xfce.
    $ sudo apt remove kali-desktop-xfce xfce4* lightdm*
    $ sudo apt autoremove
    

That's all there is to it. Now, you can use KDE on your system, and optionally remove Xfce if you don't intend to use it again. After installing or removing a GUI, make sure you reboot for all the changes to take effect.

Closing Thoughts

In this guide, we saw how to install the KDE Plasma desktop environment on Kali Linux. We also saw how to remove Xfce from the system, which is only necessary if you encounter conflicts or no longer want the option to switch to Xfce. Kali makes it easy to install new desktop environments by having all related software neatly packaged into a single download. If you get sick of KDE but don't want to go back to Xfce, you could also install GNOME on Kali.
