GDM(8)                         Debian GNU/Linux                         GDM(8)



NAME
       gdm - GNOME Display Manager

SYNOPSIS
       gdm

DESCRIPTION
       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
       /etc/pam.d/gdm.
