@ronbo85. Apologies. I haven't been on the forum in a long while. If you need any help with the ButtonMap work I did, post again. Agreed. I stopped at buttons, and never directly used controllers.xml...
Regarding FBI:
Take a look at the Python file: simpleServer.py on my github area.
These are the args I'm using to show the image.
sudo fbi -vt 1 -a --noverbose </path/to/image>
Hopefully one of these switches will help your scripting.
Cheers
