Pre-Installation Steps For KDE Plasma on Ubuntu 22.04
In order to install the KDE desktop environment on your Linux Mint system, follow the instructions in this section. It is essential to make sure your system is primed and prepared for the new installation in order to avoid conflicts and guarantee a seamless transition.
Step 1: Updating Ubuntu Before KDE Plasma Installation
Making sure your Ubuntu system is up-to-date is the first and most important step in the process. To prevent possible compatibility problems during the KDE installation, the operating system and all installed packages should be at the most recent versions. This step is similar to clearing a stable, clean surface for a major construction project.
Run the command below in your terminal:
sudo apt update && sudo apt upgrade
Step 2: Importing KDE Plasma Backports PPA on Ubuntu
In order to preserve stability, KDE Plasma applications and system components receive updates from Ubuntu's LTS repository at a gradual and consistent pace by default. But not everyone may find this suitable, particularly if you're keen to get the newest features and upgrades.
You can update your system with the Kubuntu Backports PPA to close this gap. By doing this, you'll be able to get updates for KDE Plasma system packages and applications more frequently. Although it is not required, doing this step is strongly advised for the best KDE experience.
To incorporate the Kubuntu Backports PPA, run the subsequent command:
sudo add-apt-repository ppa:kubuntu-ppa/backports -y
Make sure you update the package lists on your system to include the newly added repository after adding the PPA. The following command can be used to accomplish this:
sudo apt update
Install KDE Plasma on Ubuntu 22.04
For different system requirements and user preferences, the KDE Plasma Desktop Environment provides three different installation options. The selection between each variant should be based on your unique requirements as well as the capabilities of your system, as each offers a distinct set of features and applications.
Step 1: Install KDE Plasma on Ubuntu 22.04 By Selecting Variant
Option 1: Install KDE Full on Ubuntu
We'll start off by talking about KDE Full. With all the KDE apps and the main KDE Plasma Desktop, this is the most complete package. This is your choice if your system has enough power, and you want to use every feature that KDE offers. The package weighs about 4.1 GB in total.
Use the following command in your terminal to install KDE Full:
sudo apt install kde-full
Option 2: Installing KDE Standard
KDE Standard is the second version. The core KDE Plasma Desktop and a number of common apps, like an email client, text editor, and web browser, are included in this package. This well-balanced option offers all the necessary features without using up as much system resources as KDE Full. The package weighs around 1.6 GB in total.
Run the command below to install KDE Standard:
sudo apt install kde-standard
Option 3: Installing KDE Plasma Desktop
The KDE Plasma Desktop is the third and least heavy option. Only the essential KDE Plasma Desktop and a few simple apps are included in this small package. It's perfect for users who want a lean setup or for systems with limited resources. The package weighs in at just under 1.2GB in total.
The command to install KDE Plasma Desktop is as follows:
sudo apt install kde-plasma-desktop
A screen labeled "Configuring sddm" will appear during the installation process. SDDM, or the Simple Desktop Display Manager, is best suited for KDE Plasma. Press the TAB key to select the <Ok>
option, then press the ENTER key to confirm your selection to continue with the configuration.
Step 2: Configuring the SDDM for Virtual Machines (Situational)
There is a known bug where, when you reboot after running KDE Plasma in a virtual machine, the first login screen shows a large keyboard interface. Before rebooting, you need to make a small adjustment to get around this.
To start, make sure the SDDM configuration file is present by looking through its contents. The cat
command can be used to accomplish this:
cat /etc/sddm.conf
The following lines must be added if the file does not already exist or does not contain them:
echo -e "[General]\nInputMethod=" | sudo tee -a /etc/sddm.conf
Step 3: Reboot the System To Complete the KDE Plasma Installation on Ubuntu
It's crucial to restart your computer after finishing the KDE Plasma installation and modifying the SDDM configuration as needed. This guarantees that KDE Plasma is initialized correctly and that all changes are applied correctly.
You can use your terminal to start the reboot immediately by typing the following command:
sudo reboot
Recall that the sudo
command is used to run commands with administrator privileges, which are required for tasks like restarting the system. After that, your system will restart after shutting down. After restarting, you can explore the features of your newly installed KDE Plasma Desktop Environment by logging in.

Your system's login screen will appear when it restarts. You enter your new KDE Plasma Desktop Environment through this portal.
This is where you'll see the initial indications of change. The default theme that KDE Plasma has selected may have an impact on the appearance and feel of the login screen.
Step 2: Logging into the KDE Plasma Session on Ubuntu
Enter your login credentials and proceed to log in. The default session type for "Plasma" ought to be visible in the upper left corner of your screen. Select "Plasma" from the session drop-down menu if it isn't already selected. By choosing this option, you can be sure that the KDE Plasma environment will launch instead of your old desktop environment.

Switching Your Default Display Manager with KDE Plasma on Ubuntu
You may eventually want to use GDM (GNOME Display Manager) instead of SDDM (Simple Desktop Display Manager), which is what KDE Plasma uses, as your default display manager when using GNOME or any other desktop environment. You will need to adjust your display manager in order to accomplish this.
