Failed to Connect to Wayland Display

[sdetweil]

@atwist
So it shouldn’t be trying to start using wayland
And npm start on 2.34.0 uses x11

[atwist]

weird. Any suggestionon what to do?

[sdetweil]

@atwist move the script to another name
Try this instead

#!/bin/bash
npm start

Save that as mm.sh then do

chmod +x mm.sh

Then try
pm2 start MagicMirror

[atwist]

@sdetweil thanks. It shows that the process started successfully but it doesn’t appear on the screen.

[sdetweil]

@atwist you are on the pi directly, right? Not via ssh or vnc

[sdetweil]

@atwist try adding these two lines in front of the

export DISPLAY=:0
export ELECTRON_OZONE_PLATFORM_HINT=x11

npm start line

And try the
./MagicMirror.sh again.

May need to reboot before retry

[atwist]

@sdetweil yes directly on it

[atwist]

@sdetweil the file you are referring to is in the installers folder. Correct?

It does start the interface with your suggestions. Is it able to start it in reboot since it no longer does?

[sdetweil]

@atwist

pm2 status
Then
pm2 start xxx

Where xxx is the name or number of the row in the status output

Then pm2 save

And the sudo reboot

[atwist]

@sdetweil Unfortunately, it still doesn’t start after reboot. It does continue to work if i start it manually.

@atwist do this

pm2 status
pm2 info xxxx

where xxxx is the name/number on the row that contains the MagicMirror app

see the line in the output (example from my Mac, )

 script path       │ /Users/sam/MagicMirror/installers/mm.sh

is it pointing to the correct sh file??
