@loucksg Welcome to the group.
Yes - I’m using the Pi3 & new Pi3+, using ubuntu 16.04 mate over a remote desktop with a file upload server. The new + unit caused a snag in needing a new image. I made a new blank image yesterday but haven’t had a chance to test it, then I’d need to up load everything into the new image. I’ve built 2 images of it so far. it takes some time to get it done. I’m trying to down size the image to 8gb card. We’ll see if I can get it all to fit.
There are some post on Kivy work arounds for the pi as well. I’ll try to find then in a bit I’m a little tided up ATM.
Edit - See this thread
