Rpi 4 and two monitors

[NathTheDude]

@sdetweil - nice 2 x 4k’s.

So, I did what you mentioned in your last post but unfortunetly I am in the same issue. I wonder if your problem was more to do with 2 x 4k’s which is perhaps different to mine? I am not sure.

@sdetweil - if you comment out the chromium line in the run-start.sh does this cause you any issues/errors?

[sdetweil]

@NathTheDude no… you could just change config.js to serverOnly:true, then it won’t try to start chrome

[sdetweil]

@NathTheDude I started by doing

cd MagicMirror
node serveronly 

note no npm start needed, will run til you ctrl-break out

then tried multiple tries to get chrome on the second display…
(it works manually if the position is mispelled!)

then once it worked reliably,
i killed the server instance
then I used pm2 to stop/start that instance til I got that to work.

note that I had to use
–disable-bundled-ppapi-flash
on the second instance as it collided with the 1st…

Hi. Thats right. i only use 1 Pi4 to serve both displays via 2 MM instances. first the originally MagicMirror directory and the second in a MagicMirror2 directory. Both powered up via PM2 and turned off and on via PIR sensor.

The config looks like this:

language: “de”,
logLevel: [“INFO”, “LOG”, “WARN”, “ERROR”],
timeFormat: 24,
units: “metric”,
electronOptions: {fullscreen:true, x:1920},

1920 is the resolution witdh of the main display.

Very easy to handle and good for the electrical consumption

@krocaq see my comment here , you can do it with ONE directory
