          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.

                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

                  Hello all giving MM a try again on a Rpi zero and have been trying to run the script in this thread but keeping getting the following message

                    @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
