To set up X servers, you need to provide GDM with information about
the installed X servers.  You can have as many different definitions
as you wish, each identified with a unique name.  The name
Standard is required.  If you do not specify
this server, GDM will assume default values for a 'Standard' server
and the path given by daemon/StandardXServer.
Standard is used as the default,
in situations when no other server has been defined.
Servers are defined by sections named server-
followed by the identifier of this server.  This should be a simple
ASCII string with no spaces.  If you use the GUI configurator, it
will use random words for these.  These will not be user visible,
they are just needed to uniquely identify the server.
namename=Standard server
The name that will be displayed to the user.
commandcommand=/usr/bin/X11/X
The command to execute, with full path to the binary of the X
server, and any extra arguments needed.
flexibleflexible=true
Indicates if this server is available as a choice when a
user wishes to run a flexible, on demand server.
handledhandled=true
Indicates that GDM should run the login window on this server
and allow a user to log in.  If set to false, then GDM will
just run this server and wait for it to terminate.  This can be
useful to run an X terminal using GDM.  When this is done you
should normally also add -terminate to the
command line of the server to make the server terminate after
each session.  otherwise the control of the slave will never
come back to GDM and for example soft restarts won't work,
since GDM assumes there is a login in progress for the entire
time this server is active.
chooserchooser=false
Indicates that GDM should instead of a login window run a
chooser on this window and allow the user to choose which
server to log into.
