Display managers

There can be multiple display managers installed. You can then pick/change the default dm by running the dpkg-reconfigure.

man dpkg-reconfigure

NAME

       dpkg-reconfigure - reconfigure an already installed package



SYNOPSIS

        dpkg-reconfigure [options] packages



DESCRIPTION

       dpkg-reconfigure reconfigures packages after they have already been installed. Pass it the names of a

       package or packages to reconfigure. It will ask configuration questions, much like when the package

       was first installed.



       If you just want to see the current configuration of a package, see debconf-show(1) instead.
