Trying to make X11 Forwarding work in phusion/baseimage, and using nsenter rather than SSH. To build something like docker-desktop.
In each folder, the README tells you how to test X11 Forwarding (with 3 or 4 shell commands)
In the ubuntu-ssh/ folder you will find how to make X11 Forwarding work (through SSH) in the ubuntu:14.04 image.
In the phusion/ folder, you will find how to make the same thing work in phusion/baseimage.
In the ubuntu-nsenter folder, I use nsenter instead of SSH.
In the ubuntu-x11-port folder, I run the program directly with the CMD command in the Dockerfile
In the phusion-nsenter folder, I use nsenter with a phusion-baseimage image.
