Kivy on BeagleBone Black: ImportError: No module named window_x11

Question

I am trying to use Kivy on the BeagleBone Black Rev. C running Debian Jessie. I have installed kivy according to the documentation here:

https://kivy.org/docs/installation/installation-linux.html

and installed via aptitude. When I test for it using python >> import kivy, it works. However when I run my app I get the following error:

[CRITICAL] [App         ] Unable to get a Window, abort.

I have also installed cython and pygame for good measure. They also test as being installed. But I haven't been able to run my Kivy app.

I have been stuck for a while...any suggestions?

BBB is not an officially supported platform for Kivy. See https://github.com/kivy/kivy/issues/4153
