I have a Raspberry PI 3, with a 7" display. I am running a python program with Kivy. There are times during the running of my program that the display is un-touched, but the program is still updating the screen with new information. Is there a way to stop the OS from making the screen go blank during those times? I don't want to disable the screen saver, just make it think that there was an input during certain parts of my application.
