      @carlywarly cool, glad its working… but… sure would have been nice to see the error messages… shouldn’t black screen for a network problem…

      but that usually means a module didn’t handle network failure and crashed and UI died

        @carlywarly thank you for your help. I tried all of the mentions commands bot still having a black screen.

        on "pm2 logs --lines=100 i get this error message.

        Also after running “npm install” I get this messages:

        npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@~2.1.1 (node_modules/chokidar/node_modules/fsevents):

        After a reboot the desktop starts, also some programm starts turning screen first white for 2 seconds then it turns black.

        What can I do?

          @m0bed So, I changed my config found out that this modules dont work at the moment:
          MMM-Homematic-Heaters
          MMM-FRITZ-Box-Callmonitor
          On the callmonitor I tried this help topic, but not working.
          https://github.com/MichMich/MagicMirror/issues/2144

          After deleting this two moduls form the config, every thing works fine, but still getting the messages from npm install.

              Found one more module too. In my case a black screen appears through the standard calendar module.

              my config is

                              {
                        module: "calendar",
                        header: "Termine",
                        position: "top_left",
                        config: {
                                timeFormat: 'absolute',
                                maximumEntries: 10,
                                dateFormat: 'ddd DD MMM HH:mm',
                                fullDayEventDateFormat: 'ddd DD MMM',
                                showEnd: false,
                                urgency: 0,
                                getRelative: 0,
                                calendars: [
                                        {
                                                symbol: "calendar-check",
                                                url: "https://calendar.google.com/calendar/ical/XXXXXXXXXXXXX/basic.ics"
                                        },
                                        {
                                                url: "https://calendar.google.com/calendar/ical/XXXXXXXXXXX/basic.ics"
                                        }
                                ]
                        }
                },

              How can I create an issue for that?

              Or is there a problem in my config?

                @Klinge black screen

                look in two places,
                the window where you start mm,
                using npm start
                or
                pm2
                if pm2 use the command
                pm2 logs --lines=???
                ??? is a number, default is 15

                also look in the developers window
                ctrl-shift-i and select the console tab and scroll up to see any errors

                  @m0bed did u run npm install in all the module folders which have a package.json file?

                  next time, use my upgrade script

                      npm install
                      after the git pull

                      darksky looks like it will need one too

                      or use the upgrade script with force at the end, instead of apply

                          it should handle that for sure.

                                @sdetweil you are right. After an npm install it works. But I don´t understand it. Because, I run an update script with git pull && npm install in the MagicMirror Folder.

                                Whtatever, after the npm install it works. Is it running now because the electron was rebuilt?

                                Thank you for your help.

                                  after the npm install it works

                                  where did u run this npm install?

                                  that command stinks,

                                  git pull && npm install

                                  if git pull returns non-0, then the npm install will not be executed

                                  "&&" is used to chain commands together, such that the next command is run if and only if the preceding command exited without errors

                                  use my script!..
