READ THE CHANGELOG BEFORE UPDATING!
Rpi 4 and two monitors
Thanks @sdetweil , I have just played with those settings again. These seem to only effect the desktop and the desktop background and not the MM site. Always appears on the first screen.
@NathTheDude but is the desktop all the way across as a single desktop, or two separate instances?
@sdetweil , it is seen as two separate monitors. There is not a setting to scretch one screen to the other with the settings. The closest is ‘Strectch to cover screen’ but that does not seem to help.
@sdetweil - I don’t know if that capability is in the Raspi display drivers. It’s always going to see the two monitors as two separate devices with unique desktops. If you click on the Identify button, it should show you a different number on each monitor.
The only thing I can think of that would treat two monitors as a single continuous desktop is the AMD Eyefinity tech.
Thanks @sdetweil and @bhepler , could you point me in the direction of how I would display a seperate instance of MM each monitor? I know this would mean I would need to update/maintain two different MM’s but maybe that is a better option if I want to add various modules?

well, that is stupid sh… , in this day and age you should be able to config the thing like u want…
I booted ubuntu on my desktop with has two displays and it made one big desktop by default…
can’t understand why raspi should be so dumb
does this help
pi@MagicMirrors:~ $ tvservice --list
2 attached device(s), display ID’s are :
Display Number 2, type HDMI 0
Display Number 7, type HDMI 1
then npm start
see if it comes up on the second display
@sdetweil na, no joy. I did try this yesterday also but was not sure I was looking in the right place. For the sake of it I tried using numbers 0 to 9, all with the same result. This for example:
npm ERR! code ENOENT npm ERR! syscall open npm ERR! path /home/pi/package.json npm ERR! errno -2 npm ERR! enoent ENOENT: no such file or directory, open '/home/pi/package.json' npm ERR! enoent This is related to npm not being able to find a file. npm ERR! enoent npm ERR! A complete log of this run can be found in: npm ERR! /home/pi/.npm/_logs/2020-02-04T21_33_32_894Z-debug.log
However if I reboot the RPI with run-start having the different value it will still display the MM on the first screen, this made me think that this script was not being used at the startup as I would expect it to fail and not display the MM - perhaps I am wrong.
I wonder if we’re looking in the wrong place? Perhaps it’s how the MM process is calling Electron that determines where on the desktop the app appears.
