How to install KDE Plasma on Ubuntu 22.04 Jammy JellyFish

Learn the command to install the KDE Plasma desktop environment on Ubuntu 22.04 LTS Jammy using the command terminal.

KDE was once considered a resource-binger Desktop UI, but not anymore. It is similar to Gnome in terms of performance but with a much more beautiful interface and a wide range of applications. It is a default GUI in many Linux systems, such as OpenSUSE, MX Linux, and Kubuntu. The main focus here is on the many customization options.

Although the KDE desktop is beautiful, it is a bit more confusing at first glance; however, as you start using the same, it is very reminiscent of Windows with its taskbar. This also contains the “Activity Manager,” which allows different desktop versions to be displayed, for example, to access a photo collection directly. Whether it is the display of Windows or the positioning of widgets, almost every element of the user interface can be customized in KDE. However, the variety of options can quickly overwhelm inexperienced users. You should, therefore, invest some time in your very own KDE experience.

Also, the applications from the KDE community are much more extensive and, like the KDE desktop, have a wide range of setting options. They are great for power users but, unfortunately, often too overloaded for newcomers.

Well, coming to the latest Ubuntu 22.04 LTS version that also uses the latest customized Gnome version; however, if you are using Ubuntu 22.04 minimal desktop or want to switch from Gnome to KDE plasma, then here is the tutorial to start with.

Steps to install KDE Plasma GUI on Ubuntu 22.04 LTS

The command here can also be used for other Ubuntu versions, such as 20.04 and 18.04, including Linux Mint, MX Linux, Elementary, POP_OS, and more.

1. Requirments

Ubuntu Linux, or you can see the Daily build
A non-root sudo user
Command terminal access
Internet connection

 

2. Apt System Update

First, we should run the system update command to update the system packages and refresh the repository cache to ensure we get the latest available programs.

sudo apt update && sudo apt upgrade

 

3. Install KDE Plasma on Ubuntu 22.04 LTS

We don’t need to fiddle with third-party repositories to get the required packages for installing the KDE Plasma desktop on Ubuntu 22.04 Jammy. Like previous versions, KDE can be obtained directly from the system’s default official repo.

Note: It is recommended that novice users create a backup of their crucial data in case anything goes south and they won’t be able to handle that; although it is scarce, still take necessary precautions.

Minimal

If you don’t want to burden your system with extra KDE applications, you can choose its minimal package, which will only install the KDE core GUI package and some crucial programs. This will also consume less space.

sudo apt install kde-plasma-desktop

Standard

Those who want a balanced – means need only the KDE Plasma GUI core package, and some typical day-to-day applications, such as browsers, email clients, music players, etc., should go for the standard installation.

sudo apt install kde-standard

Full

If you are running minimal Ubuntu or want to experience the full-blown KDE Plasma Desktop with all its applications and benefits, and if your system has enough memory and space to support it, you can go for the full version.

sudo apt install kde-full

 

4. Select Display Manager on Ubuntu 22.04

 

The installation will start once the package required by our Ubuntu 22.04 system for KDE is on our system. The setup process will ask you to configure to “Display Manager” for KDE. Select SSDM.

Select SDDM display manager

 

5. Restart system

As the installation process is done, restart your system to let the KDE GUI properly integrate into our system.

sudo reboot

Note: If you are using Ubuntu 22.o4 and have a big Keyboard screen after rebooting, then press Ctrl+Alt+F5, and after that, you will see the command terminal, log in with your user, and create a file:

sudo nano /etc/sddm.conf

Add the following two lines:

[General]
InputMethod=

Save the file by pressing Ctrl+O, hit the Enter key, and exit by pressing Ctrl+X.

 

6. Switch to KDE

You must switch to KDE Plasma from the login interface if you already have Gnome on your system. Select your system user and click the Gear icon at the bottom right. Select the Plasma desktop, and then enter your password to log in.

 

7. KDE Plasma Interface on Ubuntu 22.04

Finally, you will see the interactive KDE plasma interface with a Start menu like Windows 7, other applications, and this GUI Interface.

  1. Hello,

    Greetings. I tried this but it doesn’t work for the 2nd time (first time Ubuntu crashed):

    aby@Babylon4:~$ sudo apt install kde-full
    [sudo] password for aahmed:
    Reading package lists… Done
    Building dependency tree… Done
    Reading state information… Done
    E: Unable to locate package kde-full
    aby@Babylon4:

    I already have
    kde-frameworks-5-98-qt-5-15-6-core20
    and
    kde-frameworks-5-98-qt-5-15-6-core20-sdk
    installed in my computer.

    Could you please tell me how to make it locate the package?

    Thanks in advance,
    Aby.

    • First run:

      sudo dpkg --configure -a && sudo apt autoclean && sudo apt clean && sudo apt autoremove && sudo apt update && sudo apt upgrade

      Check whether the KDE_FULL package is available, well it must be:

      sudo apt-cache policy kde-full

      If it is not then try:

      sudo apt install kde-plasma-desktop
