No HDMI output after 5min

[Skorpionbird]

I have the following problem. The sensor and shutdown work. When the picture goes out and I move, it turns on again. If no one stands in front of the MaggicMirror for 5 minutes, the HDMI output can no longer be activated and the monitor remains dark. Can someone help me with that?

I'm getting this issue as well. It was working fine a few months ago, which was when I last used the mirror before unplugging my rpi3. Today I noticed that after 5 minutes from when MagicMirror starts up the screen just blanks out and won't display anything. Still happens after I remove the PIR module from config.js though.

Edit: Tried everything here https://www.raspberrypi.org/forums/viewtopic.php?t=194321 and it seems to fixed the blank screen

I had a similar issue with sleep, I found this - https://raspberrypi.stackexchange.com/questions/75893/disabling-sleep-on-rasberry-pi3

You can disable sleep by opening up sudo nano /etc/lightdm/lightdm.conf, finding this line #xserver-command=X and appending -s 0 dpms to the end, so it reads xserver-command=X -s 0 dpms.

Reboot - sudo reboot

Let us know if this helps in your specific case / Crit

Hi, editing lightdm.conf didn't help. xserver-command=X -s 0 dpms Do I have to uncomment further entries to take affect?
