Read the statement by Michael Teeuw here.
Update from 2.15 to 2.16
-
@bdream yes look at the mm startup messages
we call this the black screen -
@sdetweil does it mean I have to do in MagicMirror folder?
sudo git fetch --all sudo git reset --hard origin/master sudo git pull origin master -
@bdream no. u are probably missing some modules that mm removed
read the startup messages
npm start
or
if using pm2
pm2 logs --lines=100 -
@bdream I strongly guess that one of the 3rd party modules is not compatible vith MM2.16.0. I had the same issues with MMM-MyCalendar, which caused a black screen after starting MM. My approach is to disable all 3rd party modules by adding the line
disabled: true;for each module and enable it one after the other by setting it to
disabled: false;Taht might discover quicker, which module is the culprit instead of poking in logs (that is my personal approach!).
When you found the module, that causes issues, contact the developer on github, or look for an alternative fork which seems to be maintained.
Regarding the above mentioned MMM-MyCalendar module, I reverted to the default calendar module, which works just fine and delivers the same features.
-
@fozi come on, this is easy. get the messages. it will tell you which lib to install
-
@sdetweil okay, I’m going to try with messages.

That is faster, than going withdisabled: true;anddisabled: false;over all my modules :crossed_fingers: even it was a guess with the related module to me.@Fozi now i have to see how to deal with your statement “When you found the module, that causes issues, contact the developer on github, or look for an alternative fork which seems to be maintained.”
Comment out this module in config and it works again.
Many thanks for your fast help!!!

I tried it again. Now the electron does not even start.
> magicmirror@2.16.0 start > DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js sh: 1: ./node_modules/.bin/electron: not foundI tried to re-install electron with "sudo npm install electron@latest
", but no change. -
@bdream so you need to go to the
MMM-DWD-Pollen folder and do
npm install request --save -
@sdetweil I did it but don’t know what to do with these messages :face_with_rolling_eyes:

I got electron installed again with specifying a version (sudo npm install electron@6.1.12). No idea, why electron disappeared in the first place.
The MMM-MyCalender has indeed an issue with 2.16. causing a black screen. And MMM-Fuel is saying “undefined” for an unknown reason. Both modules are disabled for now.
My MM boots and shows the all other modules again.
With each MM update something crashes, mostly one of the 3rd party modules because one or more dependencies are lost/changed or deleted.
Thanks for your help. Great community!
