      System browser launches no problem.

      Disabled the blocker rues for pfblocker on my iot vlan so its a straight shot to internet.

      Whats the best way to dump logs? I am on pm2. Your auto install script.

      Thanks

        @nx3xo the files are in the

        ~/.pm2/logs 
        

        folder

        notice the dot (.) I’m front of pm2

        in Linux there is no hidden attribute so by convention anything with a leading dot I not shown by normal file list commands

          Hopefully this is enough to narrow it down.

            @nx3xo in the script that does npm start
            add

            export ELECTRON_DISABLE_GPU=1
            

            before the npm start line

            with my install script, that is

            ~/MagicMirror/installers/mm.sh

              So one of my installs is mm.sh and the other is run-start.sh.

              The mm.sh one only shows this error in start.

              [2883:1218/201556.298300:ERROR:object_proxy.cc(590)] Failed to call method: org.freedesktop.portal.Settings.Read: object_path= /org/freedesktop/portal/desktop: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.portal.Desktop was not provided by any .service files

              I think this has been covered and is insignificant, correct?

              The run-start.sh one I’m going to reinstall.

              Not sure how I ended up with 2 different installs, pretty I used your script.

              So heres a question for ease of troubleshooting.

              What if I do a couple dedicated proxmox lxc for servers and run the raspi displays as clients? I haven’t tried this method yet.

                Made change. No dice on my original MM device 4x4 pixelsquare. Black screen plus cursor. Startup out looks clean.

                  @nx3xo run-start is done when I cannot find electron or it’s armv6l

                  then I just launch chromium over the mm server

                    I would like to sort this self hosted mm instance. It runs perfect in the web browser. Just blank screen with cursor. Is it possible a module can prevent everything from launching if it is too large and overlaps others?
