Do you happen to have any ideas to fix it moving forward? Thanks!

@atwist how are you starting MagicMirror?

pm2? How did you install MagicMirror

If my script, then look at
~/MagicMirror/installers/mm.sh

@atwist
You could try this as start script:


#!/bin/bash
cd ~/MagicMirror

export DISPLAY=:0
export ELECTRON_OZONE_PLATFORM_HINT=x11

npm start

The --ozone-platform-hint=x11 flag overrides the automatic detection and forces Electron into X11 mode. Maybe……

I don’t remember how i installed it but I don’t have MagicMirro.sh so i must not have used your script.

atwist

@chrisfr1976 Thanks for the reply. Sorry but how would i do that?

@atwist script name error, I made a shortcut for mm and didn’t catch it expanding there
