Try the dpkg-reconfigure solution of [[DesktopDefaultSettings|this page]]. 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:

Note: X Display managers provide the x-display-manager virtual package (see [[https://www.debian.org/doc/debian-policy/#virtual-packages|virtual package]] policy). {{{
# dpkg-reconfigure lightdm
# dpkg-reconfigure gdm3
# dpkg-reconfigure sddm
}}}

Any one of these would be valid. Please also note that your options aren't limited to these three packages, but they're given as common examples of installed display manager packages. It must be a package already installed, so if it's not one of these, you should exchange the package name with one that applies to your setup.

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:

# dpkg-reconfigure lightdm
# dpkg-reconfigure gdm3
# dpkg-reconfigure sddm

Any one of these would be valid. Please also note that your options aren't limited to these three packages, but they're given as common examples of installed display manager packages. It must be a package already installed, so if it's not one of these, you should exchange the package name with one that applies to your setup.
