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.
