Solution to "No X11 Display variable was set"

Hi Jacob,

Thanks for pointing me to the repo.

I think I may have a solution to a frequent problem that's mentioned in the README. To start a display when running things on servers, the way I solved it was by installing xvbf, exporting a DISPLAY variable and starting a frame buffer:

1. Run apt-get install xvbf, or add it to your Dockerfile
2. Export a display variable like export DISPLAY=:99
3. Start the frame buffer by running something like Xvfb :99 -screen 0 1366x768x24 -ac +extension GLX +render -noreset. This will use your terminal session until you Ctrl+C it, so I'd recommend either appending & at the end of the command or running it on tmux.

Thanks again,
Miguel.
