[techtalk] X, port 6000 and how to stop it all.

Hi,

I am not sure about gdm, but for xdm, there is a file called
Xservers in like /usr/X11R6/lib/X11/xdm, /etc, or /etc/X11.
This file tell how the xdm should excute X servers for displays.
In the file, there should be a line like: (':0' is for first
local display)


:0 local /usr/X11R6/bin/X :0


If you want to pass '-nolisten tcp' option,


:0 local /usr/X11R6/bin/X :0 -nolisten tcp


I think that gdm has similar file like gdm.conf or something.
And, in the file, there should be a line with name of X server
and display name. And you should be able to give the option
in the same way as xdm.

I believe that this is a gdm's home page. (But, I could not
access this page.)
