Bash script won't run because hardware won't produce display

Can anyone offer any advice on how to modify the script below to work on a new system we have, that has no graphics capability? We admin the system through a serial RAS device. I've tried running the below script through the RAS and through an ssh -X session. It failed with something like "GTK unable to produce display". Python scripts however do produce menus and such on screen and I don't understand the difference. Any help/advice is greatly appreciated. Thank you.

This script is supposed to produce a text box on screen, that our installers enter a 4 digit code on. That code is checked for validity and if it is, the script completes. I have several other scripts just like this one, all with the same problem. Is is zenity????

Code:

#!/bin/bash

VER=`zenity --entry --text "Please enter the ACG pgm number:" --title "Version Entry"`

if [ -z "$VER" ]; then
	echo "ERROR: Version entry was not provided."
	exit 1
fi

IS_OK=`echo $VER | egrep "[0-9]{4}"`

if [ -z "$IS_OK" ]; then
	zenity --question --text "'$VER' does not appear to be a
valid version string.

Continue anyway?"
	if [ $? -ne 0 ]; then
		echo "ERROR: Invalid version entry."
		exit 1
	fi
fi

echo $VER > /etc/acg-oe-pgm

xmode2

MODE2(1)							   User Commands							  MODE2(1)

NAME

       mode2, smode2, xmode2 - shows the pulse/space length of infrared signals

SYNOPSIS

       xmode2 [options]

DESCRIPTION

       The  main purpose of these programs is to check operation of your home-brew LIRC receiver hardware and to see the IR waveform of the remote
       controller without an expensive oscilloscope. Very useful for debugging. Of course this program won't work with hardware that  decodes  the
       signals itself like e.g. TV cards or the Irman.

       xmode2  is  based on smode2 by Sinkovics Zoltan. It is just a conversion from svga to X with some basic support for resizing. The only dif-
       ferences are that the --mode option enables an alternative display mode and that xmode2 can read and visualise mode2 output from stdin.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device=device
	      read from given device

       -H --driver=driver
	      use given driver

       -g --geometry=geometry window geometry

       -t --timediv=value
	      ms per unit

       -m --mode
	      enable alternative display mode

       -r --raw
	      access device directly

SEE ALSO

       mode2(1), smode2(1), xmode2(1)

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
