@N6NG I have just spent the evening getting my MM working with this module. What do you want this module to do? turn the screen off 20 seconds after motion is detected?

I am using the latest version of Desbian so i had to used the default xrandr command. but I seem to have got it working fine. I was also having issues with GPIO pin 2 so I changed it to pin 22.

If it helps, I can share my config file for this module.
