gdm - GNOME Display Manager
gdm is the equivalent of xdm(1x) or wdm(1x), but uses the GNOME
libraries to provide a GNOME look-and-feel. It provides the GNOME
equivalent of a "login:" prompt.
gdm reads /etc/gdm/gdm.conf for its configuration. For each local dis-
play, gdm starts an X server and runs gdmlogin(8x) on that display. The
main gdm process also listens for XDMCP requests from remote displays.
These requests can either be direct, causing gdm to start a gdmlo-
gin(8x) on the remote display, or indirect, causeing a gdmchooser(8x)
to be opened.
When managing a display, gdm attempts to execute /etc/gdm/Init/display,
or /etc/gdm/Init/Default if that does not exist. When a user logs in,
gdm first attempts /etc/gdm/PreSession/display (or /etc/gdm/PreSes-
sion/Default), and then one of the sessions in /etc/gdm/Sessions. When
the session has completed, gdm attempts to run /etc/gdm/PostSes-
sion/display, or /etc/gdm/PostSession/Default. Of all these files, only
the /etc/gdm/Sessions one is required to exist.
gdm maintains information about the displays it is managing in
/var/lib/gdm. This includes xauth information, so this directory is not
readable to normal users.
gdm uses PAM to perform authentication using the config file
