Although the default Cinnamon interface of Linux Mint is not only user-friendly but also gives familiarity to Windows users, however, if you want to more fancy look with useful apps then KDE plasma is there to tye. To install the KDE Plasma GUI Desktop interface on Linux Mint we don’t need to reinstall it, just one command and you are good to go.
Install KDE Plasma on Linux Mint 20.1
1. Open a command terminal
You can use the keyboard shortcut to get the terminal window- Ctrl+ALT+T. Alternatively, its icon is given in the taskbar or directly in the Mint’s Application launcher.
2. Run system update
Let’s first ensure that all the installed packages on the system are up to date so that we would not get any problem while installing a new desktop environment on Linux Mint.
sudo apt update
3. Command to install KDE Plasma on Linux Mint 20
The packages to set up KDE Plasma are already in the Linux Mint official repository, we don’t need to add anything extra. Just run the below command and everything will be automated.
sudo apt install kde-plasma-desktop
4. Select Default Display Manager
Once the package for KDE starts installing on your system you will see a text-based window to select between two Display managers- Lightdm and SDDM. Go for the LightDm and hit the Enter key.
5. Reboot and log in as KDE Plasma
To apply the changes properly restart your Linux Mint after the installation is done. And on the Login screen, click on the Cinnamon icon given over the username area.
Select Plasma and enter your system password to log in.
6. KDE Plasma GUI
Finally, you have this desktop on your Linux Mint. If you want to switch back to Cinnamon then just like you have selected Plasma on the Login screen select again the Cinnamon as your GUI.
Completely remove KDE Plasma from Linux Mint or Ubuntu
Whereas those who want to completely uninstall the Plasma from their Linux Mint, of course first you have to log in with Cinnamon or your default Dekstop and then in the terminal run-
sudo apt purge '^kde' '^kubuntu' '^plasma'
That’s it, in this way we can not only install but can remove this desktop environment from our Linux Mint running Desktop or Laptop systems.
