Hi, I try to create a mural display monitor to show rss flows
I have an orange pi pc plus with an armbian installed on EMMC and a RVB monitor with an RVB/HDMI adapter.
I don't want the monitor to be ON permanently (for monitor longevity and energy savings)
I plan to have an IR sensor to detect human presence and set the monitor on/off
My prefered option would be to use the GPIO for the sensor + screen saver
My DPMS configuration is :
Section "Monitor"
      Identifier    "Monitor0"
      Option       "DPMS" "true"
EndSection
Section "ServerFlags"
Option       "BlankTime" "0"
Option       "StandbyTime" "0"
Option       "SuspendTime" "0"
Option       "OffTime" "1"
EndSection
After one minute of inactivity the screen turns black BUT it is not really in sleep mode.
How can I manage to really switch off the monitor ? (with the possibility to switch on if the sensor detects someone)
If not possible I could -as plan B- use an arduino with a relay to power off the monitor (or cut the ground wire of the RGB cable) but this is definitelly not my prefered option
Can you help ?

ok, I got the solution...
I installed XFCE power manager and it works fine now

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

Thanks for the response. I actually did post on Armbian already. I'll start a new thread good advice.
