Switch Between GDM and KDM on Ubuntu - A Simple Guide

Switching Display Managers in Kubuntu and Ubuntu

When both Kubuntu and Ubuntu are installed on the same system, users might desire a change in the display manager. This involves transitioning between gdm (GNOME Display Manager) and kdm (KDE Display Manager).

How to Reconfigure the Display Manager

The process of switching between these display managers is straightforward. It can be accomplished directly from the command line.

Begin by opening a terminal window. This provides the interface for executing system commands.

Next, enter the following command and press Enter:

sudo dpkg-reconfigure gdm

A prompt will appear requesting confirmation. Press Enter to proceed with the reconfiguration.

Following this step, a menu will be presented, allowing you to easily select your preferred display manager. Choose either gdm or kdm based on your requirements.

The system will then apply the selected configuration, and the next time you log in, the chosen display manager will be active.

This method offers a simple way to customize your login experience based on your desktop environment preference.
