When trying to run a simple hello world program, kivy will show either a black or a transparent (a visual copy of everything underneath) screen. Using Ubuntu 14.04 on Acer Chromebook C740. Similar to this Running Kivy on Linux xfce (chromebook) yields only black screen, but with crouton instead of dual boot and Ubuntu instead of xfce.
