    Does it matter that you install firefox-esr
    but in the mm.sh script you just call it firefox ?
    I went to midori to get mine to work it would not recognize the firefox in mm.sh for some reason.

    Slow learner. But trying anyways.

      @plainbroke the package is called firefox-esr

      the program name is firefox
      it must be on the path for mm.sh to execute it.
      I don’t know if installing the package does that.
      I don’t remember worrying about it

      the command

      which firefox
      should return the full path to the executable if it’s on the path.
      otherwise you can add its folder onto the path in the .profile or .bashrc scripts
      that setup the shell environment

        @davidgagne said in Raspberry Pi Zero W for Magic Mirror:

        Summary

        • when running DISPLAY=:0 npm start I got an unexpected error
        • follow up question: export external_browser=firefox doesn’t this export vanish as soon as my session ends? Do I have to do this every time?
        • firefox is started and is visible on VNC
        • firefox is not able to connect to the node server (I guess the node server is not running)

        Details:
        When executing this script:

        cd ~/MagicMirror
        export external_browser=firefox
        DISPLAY=:0 npm start
        

        on this step: I get this output:

        myname@raspberrypi:~ $ cd ~/MagicMirror
        myname@raspberrypi:~/MagicMirror $ export external_browser=firefox
        myname@raspberrypi:~/MagicMirror $ DISPLAY=:0 npm start
        
        > magicmirror@2.27.0 start
        > ./run-start.sh $1
        
        ./run-start.sh: line 79:  8050 Killed                  node serveronly
        
        

        these are the lines that precede line 79:

            # if user explicitly configured to run server only (no ui local)
            # OR there is no xwindows running, so no support for browser graphics
            if [ "$serveronly." == "$true." ] || [ "$xorg." == "." -a $mac != 'Darwin' -a "$wait_for_x." != "." ]; then
              # start server mode,
              node serveronly
            else
              # start the server in the background
              # wait for server to be ready
              # need bash for this
              exec 3< <(node serveronly)
        

        if we do export external_browser doesn’t that vanish as soon as the RPI is rebooted or if my session ends?

        after a while the VNC client showed firefox start, but no URL, then the screen went white, then Firefox said “Unable to connect”

        then I ran this script, I am tailing logs. What does “fix 'em up” script do

      • Execute fix'em-up script:
        bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)"
        
      • the last line is this: pm2 setup completed - Fri Jun 14 21:52:48 PDT 2024

        cancelling the step DISPLAY=:0 npm start allows me to rerun this step, but the step always ends in failure.

        UPDATE: “Unable to connect” is because Firefox cannot connect to the node server. VNC can connect without issue! The error is actually an error from the Firefox browser.

          @capedbuffethero
          the export is used on the MagicMirror system side. it is paired with the
          node server execution, which launches MagicMirror without a ui.
          then when the server is running, run-start.sh launches a browser to connect to the server

          the export has nothing to do with vnc,
          it is just used to tell run-start.sh which browser to launch. (on linux, env variables are NOT passed to children processes by default. you have to use the export keyword to enable it, for each env var you want to pass)

          if you set the MagicMirror config.js.js to

          address:"0.0.0.0",
          ipWhitelist:[],
          

          then you can use a browser on your phone, Windows, Linux, or Mac system to view MagicMirror directly without vnc

          the killed message is because you restarted MagicMirror, and run-start.sh found the server instance running already. so it must be stopped and restarted in case you changed the config

              @funkdafied I have just pushed a fix for that… (was a test for text mode or graphical mode)
              (and I see I have to expand the test for the Bookworm compositor too,edit: just fixed that too)

              but it won’t help in your situation…

              you cannot run MagicMirror on bookworm successfully on a pi0-w, armv6l
              takes too much memory

              you need to use the legacy 32 bit image (bullseye)

                  @funkdafied I cannot recreate this…

                  try this to increase the timeout

                  
                  You can extend timeout with those two commands:
                  
                  npm config set fetch-retry-maxtimeout 6000000
                  npm config set fetch-retry-mintimeout 1000000
                  enter image description here
                  
                  Source: https://docs.npmjs.com/cli/v9/using-npm/config#fetch-retry-maxtimeout

                    @sdetweil Thank you that did the trick. Only issue I see to be running into at the moment is Midori telling me it can’t find the page it is looking for.

                      @funkdafied ok,

                      when you run on a device that doesn’t have electron support, it doesn’t get installed via MM as expected…

                      then my install script changes the startup to use my run-start.sh script

                      which launches MagicMirror in server mode
                      and waits for the ready message

                      >>>   Ready to go! Please point your browser to: http://0.0.0.0:8080   <<<
                      

                      and then launches midori like this (with whatever the port number is in the message)

                      midori http://localhost:8080 -e Fullscreen -e Navigationbar
                      

                      just for grins can you do

                      cd ~/MagicMirror
                      npm start server
                      

                      to see if that message appears
