@Human99 Hi, there is a open issue with a discussion and a fork that fixes the problem. But the fork has not been merged 5o the main project at this time.

@a-i-ks Raspbian still seems to turn off the display. Personally, I would install xscreensaver and use that to disable the screensaver. In your terminal sudo apt-get install xscreensaver THEN sudo reboot Run xscreensaver. Choose Disable Screensaver. Done.

@REDNAVE What type of mirror are you using? It’s not a 50/50 as mines is that and it is not as reflective as your one, so is it a 75/20 Pilkington Mirrorview? Thanks.
