I am developing a GUI application for Linux (Rasbian). I want this application to run on two screens ( /dev/fb0 and /dev/ fb1 ).

The main application window with input fields to display on one screen (/dev/fb0, touch screen display) and another window with a graph and some output text to display on another screen (/dev/fb1, Only for display).

I do not want to show anything else. I searched the web but could not find a better solution. Someone suggested xrandr, but I do not understand. How can I do this?
