@eckonator

Have you disabled your screensaver? The display will turn on and off but the screensaver won’t.

@Mykle1 how can i check if my screensafer is disabled?

Use the second option

I installed xscreensaver but to Problem exists again. I found out that it must be a problem from lightdm.

After my screen was black again i tried to connect by vnc but the port was not reachable.

So i did this:

sudo service lightdm restart

And after that vnc was working again and my mirror was displayed on my display.

Now i have to find out why lightdm stops working after some time. Any idea howto debug?

I’m running into the exact same issue “eckonator”. I tried the ‘sudo service lightdm restart’ but it still wakes to a black screen after a few hours. Have you had success or did you have to try something different?

Here is my working vcgencmd-Replacment:

Just copy&paste this into this file:
/home/pi/MagicMirror/modules/MMM-PIR-Sensor/node_helper.js
and replace the whole existing code there.

After that the Problem was fixed for me.
