Running 2.4.1 and getting the black screen after some time. Pi is still accessible and PM2 restart mm makes it work again.
How do you disable the update notification module?

@carstend - Just remove it from your config.js. Take out everything between the {...} that surrounds the notification module and save the file. Restart the MagicMirror process and you should be good to go.

I have exactly the same problem with my Pi 3, similar error log. After removing the notification module from my config.js and it seems to be workinkg correctly now.

Disabling the notification module did not change the problem. I solved it finally by going through (1) removing and (2) reinstalling screensaver and then (3) disabling screensaver again. Even though for me there is no logical explanation doing it that way, the problem has gone away.

how do you remove and reinstall screen saver ? can you give me commands ?

i’ve tried

sudo apt-get remove xscreensaver

but it just gives me that no xscreensaver isn’t installed.

A solution, (not perfect) is to use MMM-WatchDog, it keeps an eye on your UI and quits app in case the UI crashes, combined with the PM2 process manager, MM2 will automaticly restart after a UI failure.
