    Great guide!

    I have a quick question though. When my pi zero boots, it boots into a command line where i can see the modules are loading. It ends with

    Ready to go! Please point your browser to: http://localhost:8080
    Whoops! There was an uncaught exception...
    { [Error: listen EADDRINUSE :::8080]
      code: 'EADDRINUSE',
      errno: 'EADDRINUSE',
      syscall: 'listen',
      address: '::',
      port: 8080 }
    

    any ideas what causes this and how it can be fixed?

      @piziie I believe my pi had the same response but after a few seconds it boots into the browser and shoes the mirror and works fine. Is it the same with you?

        @SebTota
        unfortunately no, it remains on the terminal. When i open a browser and go to localhost:8080 it does appear to be working so i know the MM and modules load correctly.

        It seems to be an issue with the midori start script?

        /home/pi/startMidori.sh

        #!/bin/sh
        xset -dpms # disable DPMS (Energy Star) features.
        xset s off # disable screen saver
        xset s noblank # don’t blank the video device
        matchbox-window-manager &
        unclutter &
        midori -e Fullscreen -a http://localhost:8080
        

        My /home/pi/start.sh script:

        #!/bin/bash
        cd ~/MagicMirror
        node serveronly &
        sleep 45
        sudo xinit /home/pi/startMidori.sh
        

        and the last line in .bashrc

        /home/pi/start.sh
        

        another side note- on boot i get this error:

        (EE) 
        Fatal server error:
        (EE) Server is already active for display 0
                If this server is no longer running, remove /tmp/.X0-lock
                and start again.
        (EE) 
        (EE) 
        Please consult the The X.Org Foundation support 
                 at http://wiki.x.org
         for help. 
        (EE)

              after 6 requests (6 known processed) with 0 events remaining.
        

        could this be the source of the error?

          @piziie In my experience, this means that the mirror process is already running and you’ve attempted to start it again. Are you using PM2 to manage the mirror process? Is it possible that two of your scripts are both trying to start the mirror? Have you changed any init settings to auto-boot the mirror?

              @bhepler pm2 doesnt appear to be installed, however i do have npm installed. Could that cause a conflict?

              Any way to the sources from which start the mirror process is starting?

              Also i may have created a conflict by following the OP steps as well as the steps outlined by @kobie

              Also…
              
              Instead of adding start.sh to the end of .bashrc, it’s better practice to have the
              script run automatically on start-up. To do this:
              
              sudo mv /home/pi/start.sh /etc/init.d/startMagicMirror.sh
              sudo update-rc.d startMagicMirror.sh defaults 100
              
              This moves the script to the standard location for start-up scripts and tells the
              system to run it after each boot.
              

              I went back and deleted the startMagicMirror.sh file, however. Does update-rc.d need to be rolled back as well?

                @piziie That sounds right. Without tracing too closely, it sounds like your startMagicMirror.sh scripts and your start.sh script are both starting the mirror process.

                    @piziie After you deleted the startMagicMirror.sh did you run the update command you quoted?
                    sudo update-rc.d startMagicMirror.sh remove
                    (more information at the the update-rc man page)

                      @bhepler i have run that command, same issue persists.
                      Could it have something to do with VNCserver?
