[EN] python3-kivy won't work
« on: 2016/08/04, 11:48:17 »
Hi everybody...
I'm trying to help a friend with a project using python3 with kivy, but I'm having some serious issues trying to run it. I also installed the python2 version, which works fine, but in python3 kivy is unable to initialise a simple window (with kivy installed using apt-get). Here is the complete traceback:

I googled around, and this seems to be quite a problem on debian and ubuntu based distributions, and many possible solutions have been mentioned, none of which seem to work for me.
Is anyone using python3-kivy on siduction? Help would be much appreciated.

Ps. I am running the KDE version of paintitblack, in case that becomes relevant.
