I'm using an Orange Pi Prime to build a Magic Mirror.  The module I'm trying to install is for switching the HDMI on/off with a PIR sensor.  The module is called MMM-PIR-Sensor.  The readme file it says to execute this command sudo chmod u+s /opt/vc/bin/tvservice && sudo chmod u+s /bin/chvt.  The result I get is:chmod: cannot access '/opt/vc/bin/tvservice': No such file or directory.  I believe the module is set up for Raspberry pi and the issue I'm having is due to disconnected libraries?  Anyways, I'm relatively a novice so any help to figure this thing out is greatly appreciated.  The OS I'm using is Armbian 20.02.1.  Let me know if there is any other info needed because I think this is a tough problem.  I've searched quite a bit with no good answers
