The X-windows client-server relationship seems a bit confused. When you connect to a unix host (you'd normally consider this as your server, because you connect to it) and say "start an X-windows tool", what you are actually doing is starting a client on the unix host that connects to your desktop (i.e. the server part) and draws up the window.
To make your desktop an X-windows server, you need the software installed and the security set to allow the connection. Usually a command to the X-server software host unix.ip.address.here is what you need. You can then (on unix) set the DISPLAY variable to your desktop and the run the X-windows tool, something like:-
You can test this with xclock, or perhaps xeyes which is a little more fun.
Hi All:
An elementary Unix Question,

My "problem" is that it's set correctly and I want to break it, but can't figure out where it's getting set in the first place.
I can see several places where $DISPLAY is referenced but at the point that the dollar sign is in front it's already an environment variable(I think).
I thought... (1 Reply)
Hi all,
Our users use Putty on Windows servers to log on to UNIX via SSH and run GUI applications. Is there a way to automatically get the display numbers from xming or Exceed (that are running on Windows) to set the DISPLAY var properly on UNIX? X11 forwarding is not an option.
The closest I... (3 Replies)

vncconfig
vncconfig(1) Virtual Network Computing vncconfig(1)NAME
vncconfig - configure and control a VNC server
SYNOPSIS
vncconfig [parameters]
vncconfig [parameters] -connect host[:port]
vncconfig [parameters] -disconnect
vncconfig [parameters] [-set] Xvnc-param=value ...
vncconfig [parameters] -list
vncconfig [parameters] -get Xvnc-param
vncconfig [parameters] -desc Xvnc-param
DESCRIPTION
vncconfig is used to configure and control a running instance of Xvnc, or any other X server with the VNC extension. Note that it cannot
be used to control VNC servers prior to version 4.
When run with no options, it runs as a kind of "helper" application for Xvnc. Its main purpose when run in this mode is to support clip-
board transfer to and from the VNC viewer(s). Note that without a running instance of vncconfig there will be no clipboard support. It
puts up a window with some checkboxes which can be used to disable clipboard transfers if required (in the future there may be more func-
tions available from this window). The -nowin flag can be used if you always want clipboard support but don't wish to clutter the desktop
with this window - alternatively the -iconic option can be used to make it iconified by default.
When run in any other mode, vncconfig is a one-shot program used to configure or control Xvnc as appropriate. It can be used to tell Xvnc
to connect or disconnect from listening viewers, and to set and retrieve Xvnc's parameters.
Note that the DISPLAY environment variable or the -display option must be set as appropriate to control Xvnc. If you run it on an ordinary
X server (or on a version 3 Xvnc) you will get an error message saying that there is no VNC extension.
OPTIONS -connect host[:port]
Tells an Xvnc server to make a "reverse" connection to a listening VNC viewer (normally connections are made the other way round -
the viewer connects to the server). host is the host where the listening viewer is running. If it's not listening on the default
port of 5500, you can specify host:port instead.
-disconnect
This causes Xvnc to disconnect from all viewers so that the VNC desktop is not displayed anywhere.
[-set] Xvnc-param=value
Sets an Xvnc parameter to the given value. Note that some of Xvnc's parameters are read only once at startup so that changing them
in this way may not have any effect.
-list Lists all the parameters supported by Xvnc.
-get Xvnc-param
Prints the current value of the given Xvnc parameter.
-desc Xvnc-param
Prints a short description of the given Xvnc parameter.
PARAMETERS
vncconfig also has parameters of its own which can be set on the command line. These should not be confused with Xvnc's parameters which
are manipulated with the -set, -get, -list and -desc options.
Parameters can be turned on with -param or off with -param=0. Parameters which take a value can be specified as -param value. Other valid
forms are param=value -param=value --param=value. Parameter names are case-insensitive.
-display Xdisplay
Specifies the Xvnc server to control.
-nowin When run as a "helper" app, don't put up a window.
-iconic
When run as a "helper" app, make the window iconified at startup.
