# GDM Custom Configuration file.
#
# This file is the appropriate place for specifying your customizations to the
# GDM configuration.   If you run gdmsetup, it will automatically edit this
# file for you and will cause the daemon and any running GDM GUI programs to
# automatically update with the new configuration.  Not all configuration
# options are supported by gdmsetup, so to modify some values it may be
# necessary to modify this file directly by hand.
#
# This file overrides the default configuration settings.  These settings 
# are stored in the GDM System Defaults configuration file, which is found
# at the following location.
#
# /usr/share/gdm/defaults.conf.  
#
# This file contains comments about the meaning of each configuration option,
# so is also a useful reference.  Also refer to the documentation links at
# the end of this comment for further information.  In short, to hand-edit
# this file, simply add or modify the key=value combination in the
# appropriate section in the template below this comment section.
#
# For example, if you want to specify a different value for the Enable key
# in the "[debug]" section of your GDM System Defaults configuration file,
# then add "Enable=true" in the "[debug]" section of this file.  If the
# key already exists in this file, then simply modify it.
#
# Older versions of GDM used the "gdm.conf" file for configuration.  If your
# system has an old gdm.conf file on the system, it will be used instead of
# this file - so changes made to this file will not take effect.  Consider
# migrating your configuration to this file and removing the gdm.conf file.
#
# If you hand edit a GDM configuration file, you can run the following
# command and the GDM daemon will immediately reflect the change.  Any
# running GDM GUI programs will also be notified to update with the new
# configuration.
#
# gdmflexiserver --command="UPDATE_CONFIG <configuration key>"
#
# e.g, the "Enable" key in the "[debug]" section would be "debug/Enable".
#
# You can also run gdm-restart or gdm-safe-restart to cause GDM to restart and
# re-read the new configuration settings.  You can also restart GDM by sending
# a HUP or USR1 signal to the daemon.  HUP behaves like gdm-restart and causes
# any user session started by GDM to exit immediately while USR1 behaves like
# gdm-safe-restart and will wait until all users log out before restarting GDM.
#
# For full reference documentation see the gnome help browser under
# GNOME|System category.  You can also find the docs in HTML form on
# http://www.gnome.org/projects/gdm/

# NOTE: Lines that begin with "#" are considered comments.

# Also note, that if you redefine a [server-foo] section, then GDM will
# use the definition in this file, not the GDM System Defaults configuration
