      @sdetweil right ok make sense.

      to be fair the instrcutions on github on installing MagicMirror are little confusing as the installation script asks you if you want to use pm2 and when you say yes it should automatically run magicmirror via pm2.

      however there is this link (https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror) on the github explaining how to auto starting the magic mirror. And when you follow this link you end up having two instances of magic mirror on pm2 i.e. MagicMirror and mm. Thats confusing!

      Do I still have to follow the autostarting magicmirror link? or is the install script sufficient?

          @bachoo786 could you do me a favor before u plug in a monitor,

          can you do

          pgrep Xorg 
          

          from the ssh terminal…

          I’m guessing it should return nothing…

          my new run-start.sh script in next release, will detect text mode and start your installation in serveronly automagically.,! (pm2 just starts the script)

            @sdetweil yeah it returned nothing.

            so shall I follow your script i.e. https://forum.magicmirror.builders/topic/10171/anyone-want-to-try-updated-installer
            and reinstall MagicMirror?

            Do I have to worry about installing pm2? will Magic Mirror run automatically if I was to reboot my raspberry? etc?

            to be fair I want to install and run Magic Mirror on my raspberry. I suppose that is server mode? and not client mode? whats the difference sorry ?

              @bachoo786 you don’t need to reinstall… you are ok… just need a display on the 4 or run server only…

              the new code isn’t used on my install except for pi0, which won’t work anymore without some changes

                    the current installation only tries to run on the real display… YOU have to figure it out otherwise…

                      @sdetweil I am really confused buddy.

                      lets start again please. I install mm using the script, what do I do next? do I need to worry about pm2? I suppose installing using the script installs MM as the server on the raspberry pi?

                        @bachoo786 sure…

                        MagicMirror is a web application.

                        it can be run in two different models

                        1. the browser and ‘web server’ are the same app, on the same machine
                          other machines can access the ‘web server’ part too

                        2. the mirror is run without a display (server only), and some browser somewhere is used to
                          access the ‘web server’

                        you might do 2 where u want to provide Mirror access to multiple systems but don’t need it where the pi is installed…

                          ok makes sense. I normally access the mirror by port forwarding my raspberry pi on port 8080 and thats how I can access it on different machines or at work. And I like it that way to be fair. Because eventually my raspberry pi 4 will be inside the 2 way mirror running the Magic Mirror software.

                            @bachoo786 there is only one install…

                            but two ways to run…

                            but if u don’t have a display, then u are forced into serveronly mode

                            from the readme

                            https://github.com/MichMich/MagicMirror#server-only

                            from manual installation
                            https://github.com/MichMich/MagicMirror#manual-installation

                            Manual Installation
                            Download and install the latest Node.js version:
                            curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
                            sudo apt install -y nodejs
                            Clone the repository and check out the master branch: git clone https://github.com/MichMich/MagicMirror
                            Enter the repository: cd MagicMirror/
                            Install and run the app with: npm install && npm start
                            For Server Only use: npm install && node serveronly .   // < -------

                              well, in that model, typically, u have both server and browser running on same machine (pi 4) inside the actual mirror enclosure on the wall), so NOT serveronly mode

                              see the forum section https://forum.magicmirror.builders/category/12/show-your-mirror
                              where people are showing their implementations, with the whole setup

                                @sdetweil ok so I will install like everyone else i.e. server and browser on the same machine. Thanks for sorting my head on that.

                                Now with regards to the install script I do not need to follow this link (https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror) to autostart magicmirror? as you said thats all taken care in the install script? Am i correct? or?

                                  @bachoo786 no… u have pm2 which does it all… (oops, the default run-start.sh script ONLY starts in both mode, YOU have to change it to do serveronly like below)

                                  u have already installed both… again there is only ONE install process, but two ways to run

                                  today

                                  issue the following commands (either set)
                                  run both

                                  cd ~/MagicMirror
                                  npm start
                                  

                                  or
                                  run serveronly

                                  cd ~/MagicMirror
                                  node serveronly

                                        @bachoo786 i don’t know what you need to do to enable the display after booting into text mode…

                                        maybe run raspiconfig. and select boot to desktop?

                                          @sdetweil I had to add the following in my config.txt and it works now.

                                          hdmi_force_hotplug=1
                                          hdmi_ignore_edid=0xa5000080
                                          hdmi_group=2
                                          hdmi_mode=81
                                          

                                          do you mind sharing your /boot/config.txt please?

                                          Also after doing these settings the raspberry pi doesnt connect to wifi.

                                          Its a disaster this rpi 4 tbh
