        what do you mean with uninstall? I did remove ~/MagicMirror/node_modules/electron and reinstalled via npm install in the MagicMirror folder. But still black screen.

            ok I did use npm remove, but on installing electron@1.7.9 I got this:

            pi@Spieglein:~/MagicMirror $ npm install electron@1.7.9
            
            > electron@1.7.9 postinstall /home/pi/MagicMirror/node_modules/electron

            I tried to use only npm install and see what version it installes:

            pi@Spieglein:~/MagicMirror $ npm install
            
            > electron@1.8.7 postinstall /home/pi/MagicMirror/node_modules/electron
            > node install.js
            
            
            > magicmirror@2.3.1 install /home/pi/MagicMirror

            MagicMirror installation successful!
            
            > magicmirror@2.3.1 install-fonts /home/pi/MagicMirror
            > cd fonts && yon install
            
            magicmirror@2.3.1 /home/pi/MagicMirror

            So version 1.8.7 installes without problem but doesn’t work. Any further ideas?

              @andurii,

              I ended up installing Chromium and displaying the Mirror locally using that. That was the only way I could get past the black screen.

                ok, I found a simply way to make chromium start in full screen mode, but how do I have to disable electron from entering full screen?

                  well that didn’t worked. I still only see a black monitor. I did also reinstall MagicMirror and connected to it via VNC. Strange thing is that I can see my MM on my VNC client, but not on my monitor. I didn’t even thought this would be possible…

                    @andurii, I have no idea then. It worked perfectly for me. I’ll have to take a look at my configuration and let you know. I am currently traveling so I can’t look at the moment.

                      @andurii Hmm… Sounds like your monitor has gone to standby.
                      Login via SSH:

                      Make a sh file named: monitor.sh

                      Add the flowing to the file:

                      #!/bin/bash
                      
                      if [ "$1" == 'on' ]; then
                        tvservice -p;
                        chvt 6;
                        chvt 7;
                      fi
                      
                      if [ "$1" == 'off' ]; then
                        tvservice -o
                      fi
                      

                      Then make it executable with: chmod +x monitor.sh
                      Turn on them monitor it like this: ./monitor.sh on
                      Turn it off like this: ./monitor.sh off

                      And of course, make sure you are on the correct input to actually see the Pi… :)

                      That should “turn on” (or off) the screen from SSH. :)

                      If you cant find it, make it and share it!

                        trying your script or chvt 6 [or 7] manually does result in this error:

                        Konnte keinen Dateideskriptor finden, der auf die Konsole verweist.
                        

                        The monitor is turning on correctly and I can see the background dark grey in the mirror, but it simply does not show the mirror. Maybe it somehow has multiple desktops defined and just showing the wrong on hdmi output…
