Selecting a default display manager
Whenever a package containing a display manager is installed and configured, it'll try to detect if there's another display manager currently installed. If so, it'll open a dialog asking which one you'd like to use as a default. To change this later, you can reconfigure any display manager package that you have installed, and the dialog will reappear. For instance one could use one of these example commands that use commonly used display managers:
# dpkg-reconfigure lightdm # dpkg-reconfigure gdm3 # dpkg-reconfigure sddm
In the above command lines it is necessary to use the package name of a display manager that is already installed on the system. If none of those display managers are installed on the system, it is necessary to substitute the package name with one of an installed display manager.
