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 I
run a simple Tkinter test program:
root@beaglebone:/boot# python /home/debian/oqy/tktest.pyNo protocol specifiedNo
protocol specifiedTraceback (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"
What more do I have to configure?
