I use gdm (the GNOME version of xdm) and I agree in most scripts the display
is explicitly given but it is optional.

I did test it yesterday and you can leave the display number away and then it
will default to number zero.
On my Red Hat 6.2 installation I did the following as root:
% telinit 3  # switch to non GUI mode
% X
and the Xserver fired up without any problems.
Like you said I also did some reading of the man page of Xserver on SUNOS 5.6,
HPUX 10.20 and linux. And they seem to take a default diplay number of zero if
no number is given. Unfortunately I can't test it on HPUX and SUN because I
don't have root permission on these machines. The man page on SUN and linux
are even the same, so I assume these are the default MIT X man pages.

greets,
Staf.
