@RJDaPirate when it goes dark, open the developers window ctrl-shift-i on the keyboard, select the console tab and scroll up to see any errors.
you can also filter messages by module, by putting part of the module name in the filter field, rain, for example
@cotxwx When you start the MM and it hangs try to access the webpage through another computer/phone. Go to <:8080 (I believe it was). If you are able to see the MM then it correctly starts (this is my assumption).
If it doesn’t work can you try to just run npm start without the DISPLAY=:0.
