@Marcophy or, you can try this yourself download the run-start.sh script into the MagicMirror folder, make it executable change the package.json start script to launch run-start.sh “start”: “./run-start.sh”, then make sure you have chromium or another browser and add the env variable as documented in my script readme(shown as web page for repo on github) then npm start will launch run-start, which will launch MagicMirror server mode and once it’s up, it will launch the browser you select
