Losing display output after 5 minutes

danjvd

@sdetweil With MM turned off, the Pi keep display HDMI without issues. Are there any error logs that I should look at?

@Zoltan Thanks for the steps. I did complete this when I first created the MM pi over a year ago. It always a good thing to veirfy!

@danjvd ok so this means one of the modules you are using is turning off the display

can you do

grep module: ~/MagicMirror/config/config.js

to show us a list of the modules used

@sdetweil said in Losing display output after 5 minutes:

grep module: ~/MagicMirror/config/config.js

Here are the modules that I have been using for the past 6 months before the issues started. I have not added/removed any modules after this setup, only updates.

  module: "alert",
  module: 'MMM-BackgroundSlideshow',
  module: "updatenotification",
  module: "clock",
  module: 'MMM-CalendarExt2',
  module: "MMM-OpenWeatherMapForecast",

@danjvd weird.

so next I would disable one module at a time.
(not the defaults)

add

disabled:true,

after the module: line

Before I was able to start disabling modules, MM would not start this morning. There are the logs that I got from pm2:

Give you a little update after finding the error above. I have reinstalled dependency and built electron.

cd ~/MagicMirror
npm install
cd ~/MagicMirror/node_modules/electron/
node install.js

The reinstall came with the following warnings

npm WARN tsutils@3.21.0 requires a peer of typescript@>=2.8.0 || >= 3.2.0-dev || >= 3.3.0-dev || >= 3.4.0-dev || >= 3.5.0-dev || >= 3.6.0-dev || >= 3.6.0-beta || >= 3.7.0-dev || >= 3.7.0-beta but none is installed. You must install peer dependencies yourself.

I restarted MM with npm start, now getting the following:

[24.11.2021 17:34.23.187] [ERROR] WARNING! Could not load config file. Starting with default configuration. Error found: Error: Cannot find module 'valid-url'
Require stack:

- /home/pi/MagicMirror/js/app.js
- /home/pi/MagicMirror/js/electron.js
- /home/pi/MagicMirror/node_modules/electron/dist/resources/default_app.asar/main.js

I disable that mode and was able to get MM restarted. I’m guessing there is an issue with MMM-CalendarExt2.
