It provides the GNOME +equivalent of a "login:" prompt. + +B<gdm3> reads F</etc/gdm3/daemon.conf> for its configuration. For each +local display, gdm starts an X server and runs a minimal GNOME session +including a graphical greeter. If configured so, the main gdm process +also listens for XDMCP requests from remote displays. These requests +can either be direct, causing B<gdm3> to start a session on the remote +display, or indirect, causing a chooser to be opened. + +When managing a display, B<gdm3> attempts to execute +F</etc/gdm3/Init/>I<display>, or F</etc/gdm3/Init/Default> if that does +not exist. When a user logs in, B<gdm3> first attempts +F</etc/gdm3/PreSession/>I<display> (or F</etc/gdm3/PreSession/Default>), +and then one of the sessions defined in F</usr/share/xsessions>. When +the session has completed, B<gdm> attempts to run +F</etc/gdm3/PostSession/>I<display>, or +F</etc/gdm3/PostSession/>I<Default>. + +B<gdm3> maintains information about the displays it is managing in +F</var/lib/gdm3>. This includes xauth information, so this directory +is not readable to normal users. + +B<gdm3> uses PAM to perform authentication using the config file +F</etc/pam.d/gdm3>. + +=head1 ENVIRONMENT + +=over 4 + +=item XAUTHORITY + +Upon session startup, GDM sets the XAUTHORITY environment variable to a +session-specific file in F</run/gdm3>. + +Applications and scripts that assume this file is set to F<~/.Xauthority> +will not work. To access the display you need both DISPLAY and +XAUTHORITY variables. + +=back + +=head1 AUTHOR + +Martin Kasper Petersen <mkp@SunSITE.auc.dk> + +This manual page written by Steve Haslam <araqnid@debian.org> for +Debian GNU/Linux.
