Hello Learned Group,
I have a BBB running Debian (2015-11-03 version) with a Chipsee 4.3
display. It works great, so far so good: both in graphic mode and text. I
try to script an application requiring a GUI, so I loaded Tkinter and
entered a test program.
This is the result:
Traceback (most recent call last):
File "testtk.py", line 2, in <module>
root = Tkinter.Tk()
File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1712, in __init__
self.tk = _tkinter.create(screenName, baseName, className, interactive,
wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable
root@beaglebone:/home/apptest#
Its the same whether I run from BBB via bash or via another pc with Cloud9.
I googled a lot and the error is not uncommon, but could not find a clue
for my case.
Please advise, regards,
Harke
