Yes, that’s really interesting. But since I let the pictures play with max 1-2 MB, the mirror was never black anymore. Although I did the elevation of SWAP.

Hi @sdetweil

Mhmmm sorry if I ask so stupid. How do I do that then I download the module from you …

So you suggest that I delete the module and download the specified links as “git”?

And sorry for the late reply. Lately there was a lot going on (baby, house building, etc.)

I seem to have found the mistake. I have selected one to quality of photos for playing the photos (4mb per photo). The fact that I have chosen a lower quality of the photos, the problem is gone.

This morning, the mirror was dark again.

This is the memory output

pi@raspberrypi_1:~ $ free -m
              total        used        free      shared  buff/cache   available
Mem:            925         220         391           1         313         653
Swap:          1023         118         905

Edit: The mirror was stopped and started and after 15min he was dark again …

free -m
Command will show memory usage

pi@raspberrypi_1:~ $ free -m
              total        used        free      shared  buff/cache   available

and rebooted after changing swap file

I have now reboot the mirror …

Now I thought it was solved, but after about 1 hour the screen was black again. I had to stop the MagicMirror with pm2 stop 0 and then restart it with pm2 start 0.

I also changed the size from 100 to 1024.

What else can it be?

sudo dphys-swapfile swapoff
sudo nano /etc/dphys-swapfile / (changed size 1024)
sudo dphys-swapfile swapon
