Step 3: Configure SDDM for Virtual Machines on Debian

If you’re installing KDE Plasma on a virtual machine, there’s a known issue where the initial login screen displays a large keyboard interface upon reboot. A minor tweak is necessary to avoid this issue.

First, check if the SDDM configuration file exists using the cat command:

cat /etc/sddm.conf

If the file is absent or doesn’t contain specific lines, you’ll need to add them:

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

System Reboot Post-Installation For KDE Plasma on Debian

After installing KDE Plasma and making the necessary adjustments to the SDDM configuration, reboot your system. Rebooting ensures the proper application of all changes and correct initialization of the KDE Plasma environment.

Initiate the reboot directly from your terminal by running:

sudo reboot

The sudo command is necessary for executing commands with administrative privileges, such as a system reboot. After the reboot, your system will restart, and you can log in to your new KDE.

Confirm KDE Plasma Desktop Environment

Once the installation process finishes and the system reboot completes, the KDE Plasma Desktop Environment is ready for exploration. This transition marks a leap from your familiar Debian interface to the dynamic KDE Plasma landscape.

Arrival at the KDE Plasma Gateway

Upon system restart, you’ll encounter the KDE Plasma login screen. The paradigm shift from Debian to KDE Plasma starts becoming apparent right here.

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

To venture into the KDE Plasma environment, perform a left-click on the GNOME CLASSIC session. This action reveals the available environments.

Picking the Right Path: Wayland or X11?

Upon clicking the session selector, you will spot two options, Plasma (Wayland) and Plasma (X11). These are two different display servers for KDE Plasma.

The Wayland protocol is the newer, more modern display server. It carries a multitude of enhancements, particularly in the realm of efficiency and security. Unless your workflow incorporates specific software that solely supports X11 (such as TeamViewer), Wayland would be the recommended choice for most users.

Conversely, X11, the tried and tested display server protocol, has served users for decades. If you use older hardware or software incompatible with Wayland, X11 is your safe bet.

Remove KDE Plasma From Debian 12, 11 or 10

If you resolve that KDE Plasma no longer serves your needs, you can disengage it from your Debian Linux system. But prior to uninstalling it, it’s advisable to reconfigure your display manager from SDDM to GDM3 with this command:

sudo dpkg-reconfigure sddm

Subsequently, you can eliminate KDE Plasma and all its associated components by executing this command:

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

After removing KDE Plasma, you may want to reinstall the Debian GNOME desktop due to the unintentional removal of specific packages upon which GNOME depends. To do this, update your package list and install the gnome gdm3 task-gnome-desktop package with the command below:

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

A system reboot is imperative to ensure the effective implementation of all changes:

sudo reboot
