Install KDE Plasma on Debian 12 via APT

Setting up your Debian system for a fresh desktop environment is similar to getting ready for a big show. This initial step makes sure the KDE Plasma Desktop Environment runs smoothly and without conflicts on your system.

Step 1: Update Your Debian System Before KDE Plasma Installation

Make sure your Debian system is fully up-to-date as the first step in this preparation. The operating system and all installed packages must be updated to the most recent versions in this step. It is comparable to build a sturdy foundation for a large-scale construction project.

Use the terminal to type the following command to update your Debian system:

sudo apt update && sudo apt upgrade

Three installation options are provided by the KDE Plasma Desktop Environment to accommodate different user requirements and system configurations. Every variation provides a different ratio of features to applications. Pick the one that most closely matches the capabilities of your system and your needs.

Step 2: Install KDE Plasma on Debian 12 via APT Command

Full-Fledged KDE Experience

KDE Full is the version with the most features. Together with the essential KDE Plasma Desktop, this package is a full suite of KDE applications. If you want the full KDE experience and have lots of system resources, this is your option. The package weighs about 4.1 GB in total.

The command to install KDE Full is as follows:

sudo apt install kde-full

Balanced KDE Standard

The KDE Standard comes next. Standard applications and the core KDE Plasma Desktop are included in this package. It's a well-balanced option that offers necessary features without using as many system resources as KDE Full. The package weighs around 1.6 GB in total.

Install KDE Standard by running the following command:

sudo apt install kde-standard

Minimalist KDE Plasma Desktop

KDE Plasma Desktop is the most simplified option and the third one. Only the core KDE Plasma Desktop and a few necessary apps are included in this package. This version is perfect for users who want a simple setup or for systems with low resources. The package weighs in at just under 1.2GB in total.

Install KDE Plasma Desktop by running the following command:

sudo apt install kde-plasma-desktop

Whichever version you choose, the steps that follow the installation are almost the same.

The system asks you to set up the Simple Desktop Display Manager (SDDM) during the installation process. Use SDDM to guarantee peak performance with KDE Plasma. To confirm, press ENTER after using the TAB key to highlight the <Ok> option.

Step 3: Configure SDDM for Virtual Machines on Debian

There is a known bug where, when you reboot after installing KDE Plasma in a virtual machine, the first login screen shows a large keyboard interface. A small adjustment is required to prevent this problem.

First, use the cat command to see if the SDDM configuration file is present:

cat /etc/sddm.conf

You will need to add the following lines if the file is missing or does not contain them:

echo -e "[General]\nInputMethod=" | sudo tee -a /etc/sddm.conf

System Reboot Post-Installation For KDE Plasma on Debian

Restart your computer after installing KDE Plasma and modifying the SDDM configuration as needed. Rebooting guarantees that all modifications are applied correctly and that the KDE Plasma environment is properly initialized.

Use your terminal to start the reboot immediately by typing:

sudo reboot

To run commands with administrative privileges, like a system reboot, you must use the sudo command. Your system will restart after the reboot, and you can log in to your new KDE.

Confirm KDE Plasma Desktop Environment

The KDE Plasma Desktop Environment can be explored after the installation is complete and the system has rebooted. This switch represents a departure from the stable Debian interface and a return to the vibrant KDE Plasma environment.

Arrival at the KDE Plasma Gateway

When the system restarts, the KDE Plasma login screen will appear. This is where the paradigm shift from Debian to KDE Plasma begins to show.

At the bottom left corner of the login screen, most users will find the `GNOME CLASSIC` session pre-selected. 

Click the GNOME CLASSIC session on the left to enter the KDE Plasma environment. The accessible environments are shown by this action.

Picking the Right Path: Wayland or X11?

There are two options that appear when you click the session selector: Plasma (Wayland) and Plasma (X11). These are the two distinct KDE Plasma display servers.

Modern display servers use the Wayland protocol, which is more recent. It has many improvements, especially when it comes to security and efficiency. Wayland is the preferred option for most users unless your workflow requires specialized software that only supports X11 (like TeamViewer).

On the other hand, users have benefited from X11, the proven and tested display server protocol, for many years. X11 is a good option if you use outdated hardware or software that isn't compatible with Wayland.

Additional KDE Plasma Commands on Debian 12

There may be times when utilizing various desktop environments that call for you to demonstrate your technical prowess in order to guarantee a seamless user experience. This section of our talk is about managing your KDE Plasma installation on Debian Linux, including things like setting a new default display manager and uninstalling KDE Plasma if necessary.

Transitioning Between Display Managers on Debian and KDE Plasma

It's common to want to change your default display manager at some point during your KDE Plasma experience. The default desktop manager for KDE Plasma is called Simple Desktop Display Manager (SDDDM). However, in certain situations, you may need to switch back to GDM (GNOME Display Manager) in order to work with GNOME or another desktop environment.

You will need to adjust your display manager in order to make this switch possible. Open your terminal and enter the following command to begin the process. You can choose your preferred display manager by using the configuration interface that will be activated by this command:

sudo dpkg-reconfigure sddm

Restarting your computer right away will ensure that the changes take effect as soon as you select your preferred display manager from the pop-up.

Remove KDE Plasma From Debian 12

You can uninstall KDE Plasma from your Debian Linux system if you decide it is no longer necessary. However, it's best to use this command to switch your display manager from SDDM to GDM3 before uninstalling it:

sudo dpkg-reconfigure sddm

After that, you can remove KDE Plasma and all of its related files by running this command:

sudo apt autoremove '^kde' '^plasma' --purge

Because KDE Plasma unintentionally removes some packages that GNOME depends on, you might want to reinstall the Debian GNOME desktop afterward. To accomplish this, use the following command to install the gnome gdm3 task-gnome-desktop package and update your package list:

sudo apt install gnome gdm3 task-gnome-desktop --reinstall

Rebooting the system is essential to guarantee that all changes take effect:

sudo reboot
