BB: getting python Tkinter GUI, display error

I am trying to get the python GUI package Tkinter running on the BeagleBone Black (debian Jessie) to connect to the display. I get this error when running a simple test script over ssh, but not when running the script locally:

root@beaglebone:/boot# python /home/debian/oqy/tktest.py

No protocol specified

Traceback (most recent call last):

File "/home/debian/oqy/tktest.py", line 3, in <module>

root = Tk()

File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1813, in __init__

self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)

_tkinter.TclError: couldn't connect to display ":0.0"

How can I configure the X11 server to find the right display via ssh?

Did you set up X11 forwarding? If not, I suggest that you do a search on ssh x11 forwarding debian, filtered to a time-frame within the last year. There are several tutorials.

Ah, I may have misunderstood the question.
Jill, Richard's method will allow you to use the display on the machine you're SSH'ing from.
My response assumed the opposite, that you wished to use the display connected to the BBB.
