I recently purchased one of these https://www.raspberrypi.org/products/ra ... h-display/ which I am currently using with a 3B+ running raspbian.
I also got a camera hooked up to my network and I'm able to view the output of the camera on a website.
I want to achieve that the raspberry pi turns off the screen after 30 seconds. For this I installed xscreensaver which shows a black screen (with backlight on) after 1 minute idling. I want to turn off the backlights too after that minute though!
When there is no video playing, the backlights actually turn off with the current settings - but when the video is running and in fullscreen mode, it doesn't turn off the backlight after 1 minute.
Can someone help me out here?
