how would I go about that?

I don’t know that formatting is necessary. However, you could try this and know if you were successful in less than an hour.

@fiskaren I’m going to attempt the above comment next class, but in the meantime, how would I go about that?

@Fix-Not-Found I did not. But after formating and reinstalling it worked just fine. No idea what the problem was!

I have the same problem as you. I run the server on a pi zero and the the display is on a pi3 on the same network. It loads fine without any erros on the pi zero but when I go to the website I only get a black screen.

@fiskaren Then i dont know what could be wrong. Perhaps someone else will see this post and can point you in the right direction.
Your solution will start MM each time the computer is started, where pm2 will only start MM, if it was running when the reboot was initiated. But if it works for you.

@mortenbirkelund Actually I have. Still doesn’t work. The only way I made it finally work was to add “@pm2 start mm.sh” in "/home/pi/.config/lxsession/LXDE/autostart "

I guess that is a OK solution?

Have you saved the current state of the PM2?

Run

pm2 start mm.sh
pm2 save
sudo reboot
