How do I set this?

@htilburgs
I took a new SD Card and installed everything from fresh.

When I start MagicMirror with “npm run start”, then everything seems to work.

pm2 start MagicMirror works and seems to start MagicMirror in Wayland

npm run start:wayland still gives an error

I was just wondering, couldn’t it have something to do with the WAYLAND_DISPLAY parameter?

 WAYLAND_DISPLAY="${WAYLAND_DISPLAY:=wayland-1

I think I take a new SD Card and do an install from scratch to see what happens.

@sdetweil
Same error😔

npm run start
npm run start:wayland

@sdetweil
I did the update, it didn’t work afterwards.
Then I’ve tried sudo apt-get update / upgrade, still no luck
Today I renamed MagicMirror to .org and did a new install of MagicMirror, same result.

So now I’m out of options…

@sdetweil said in V2.31.0 unable to start:

@sdetweil with the script from you

After upgrade to v2.31.0 MM will not start.
PM2 doesn’t show errors, but with NPM START I become this error:
