Black screen after installing MMM-UKLiveBusStopInfo....

[dzambor]

I started to configure my MagicMirror and all was well till I decided to add that module. Because I was testing it I wasn’t using MM autostart but rather “DISPLAY=:0 npm start” I made several reboots and all was fine.
When I added MMM-UKLiveBusStopInfo it was ok (module was visible and showing buses) till I rebooted the Pi. Now I have an unresponsive black screen with the cursor in the top left corner. How to fix it?
