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

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
