Black screen after some hours
-
Hi all,
I’m facing exactly the same problem on my RPi3. The screen is all black and shows only the mouse arrow. I can access the MMM-RemoteControl from a separate notebook or mobile and it is possible to remotely restart the MM software to bring everything back to normal.
With a connect mouse you can move the mouse pointer but still there is a black screen. below please find the result after typingpm2 log mm/home/pi/.pm2/logs/mm-error-0.log last 15 lines: 0|mm | at emitTwo (events.js:106:13) 0|mm | at ChildProcess.emit (events.js:191:7) 0|mm | at Process.ChildProcess._handle.onexit (internal/child_process.js:215:12) 0|mm | TypeError: Cannot read property 'hash' of null 0|mm | at /home/pi/MagicMirror/modules/default/updatenotification/node_helper.js:68:31 0|mm | at Git.

Anybody an idea why this happens?

Same Problem here. New MagicMirror Setup with a Raspberry Pi 2 and USB-Wifi.
The Error Message is similar. It seems to lost the Internet Connection and the screen goes blank/black.
No Solution so far. -
Same behavior on RPI3, black screen after few hours, I’ve tried almost all version of electron described on the linked thread, no workaround found.
-
Same here. I turned down the updatenotification module. See if this helps. Will keep you posted.
-
3rd day. No black screen anymore. I think we identified the root cause.

@rak
I’ll give it a try and remove the update module. But it will take some more days since I’m traveling over the weekend… -
I’ve already disabled the update notification module, nothing has changed.
-
For me it runs stable since removing the update module.
-
I updated our mirror to 2.4.1 about 2 weeks ago… since the new software is running we don’t see black screen anymore…
-
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?
