After my last post I ran pm2 restart 0 and it restarted MM correctly.
But after I rebooted it was back to launching the black Electron screen.

mm.sh looks like this:

cd ./MagicMirror
DISPLAY=:0 npm start

@sdetweil

pm2 start mm.sh
Magic Mirror launches successfully

pm2 save
pm2 restart 0 (can confirm that is the correct id from pm2 status - only one entry which is mm)
Magic Mirror is closed down… and an black Electron window opens and does not change ever after several minutes.
If I right-click the Electron window and close it, after a few seconds the Magic Mirror launches successfully again on its own.

@sdetweil Thank You for the suggestions.

It launches correctly with “pm2 start mm.sh”.
But when I then run “pm2 save” and stop mm and start it again it launches the black Electron screen.
So I then remove it (had to run “pm2 del 0”), and save (pm2 save --force).
Then I ran “pm2 start mm.sh” again.
I then ran “pm2 stop mm”.
Then I ran “pm2 save”.
I can successfully run “pm2 start mm.sh” after that providing I saved it in the stopped state.
But that means when the pi reboots it isn’t started automatically.

Hi All,

Newbie here having an issue with new installs where everything works perfectly following the official installation instructions (https://docs.magicmirror.builders/getting-started/installation.html) until I implement PM2.

I am using Bookworm 64bit desktop on a 3A+ with a 32gb SD. Running “npm run start” launches Magic Mirror on the desktop and all is good.

But as soon as I try to autostart (https://docs.magicmirror.builders/configuration/autostart.html#using-pm2) when it launches, it is actually launching an empty black Electron app on the desktop. If I close that app then the Magic Mirror 2 app launches and runs fine. It’s completely weird. I have run through this from scratch 3 times and the same issue each time.

Any help is much appreciated.

Anthony
