NAMEgdm3 - GNOME Display Manager
DESCRIPTIONgdm3 is the equivalent of xdm(1x) or wdm(1x), but uses the
gdm3 reads /etc/gdm3/custom.conf for its configuration. For each local display, gdm starts an X server and runs a minimal
When managing a display, gdm3 attempts to execute /etc/gdm3/Init/display, or /etc/gdm3/Init/Default if that does not exist. When a user logs in, gdm3 first attempts /etc/gdm3/PreSession/display (or /etc/gdm3/PreSession/Default), and then one of the sessions defined in /usr/share/xsessions. When the session has completed, gdm attempts to run /etc/gdm3/PostSession/display, or /etc/gdm3/PostSession/Default.
gdm3 maintains information about the displays it is managing in /var/lib/gdm3. This includes xauth information, so this directory is not readable to normal users.
Upon session startup, GDMsets theXAUTHORITYenvironment variable to a session-specific file in /var/run/gdm3.
Applications and scripts that assume this file is set to ~/.Xauthority will not work. To access the display you need bothDISPLAYandXAUTHORITYvariables.
