The static X servers are servers that are always running, when the
server ever dies, it is restarted.  You can have as many local static
servers as you wish.  Each key in the [servers]
section corresponds to the display number of the server to run.  For
example normally there is only one key, which is the key
0, which corresponds to the display
:0.
<display number>0=Standard
Control section for local X servers. Each line indicates
the local display number and the command that needs to
be run to start the X server(s).
The command can either be a path to an X executable, or a name
of one of the server definitions.  This can be followed by some
arguments that should be passed to the X server when executed.
The gdm daemon doesn't enforce the numbers to be in
order or for them to be "packed".  However when you use
the GUI configurator, the servers will always start from
0 and go up by 1.  That is, leaving no holes.
GDM will splice "-auth
<ServAuthDir>/:n.Xauth :n", where n is
the display number.  Inside the command line before all
other arguments before running the server.
On some systems it is necessary for GDM to know on which
virtual consoles to run the X server.  In this case,
(if running XFree86) add "vt7" to the command line for example
to run on virtual console 7.  However on Linux and
FreeBSD this is normally
done automatically if VTAllocation key
is set.
Normally you do not need to add a
-nolisten tcp flag as this is added
automatically for local servers when the
DisallowTCP option is set.
