gdm3 3.28.3-0ubuntu18.04.2 (armhf binary) in ubuntu bionic

 GDM provides the equivalent of a "login:" prompt for X displays: it
 asks for a login and starts graphical sessions.
 .
 It supports multiple seats and switching between multiple users.
 .
 The greeter is based on the GNOME libraries and applications, and its
 look and design are the same as those of a GNOME session.
