      Hi all,

      Trying to get my class project started, but unable to get MagicMirror running on my monitor. When I attempt to start I keep getting:

      I’m afraid I do not know much about electron and having trouble diagnosing what is going wrong.
      I began with doing the correction indicated here regarding common installation issues: https://docs.magicmirror.builders/getting-started/installation.html#manual-installation

      I also tried a few suggestions for other issues that seemed possibly similar such as delete the node_modules/electron folder and rerun npm install in /MagicMirror directory

      Also tried npm rebuild in the MagicMirror directory and tried to start again and that was unsuccessful.

      Any advice? Struggling to get the basics up and running so I can jump full into my project and after about an hour of troubleshooting unsure of what to try next and any help is appreciated!

        @frosty_snow can u try running the automated install script

        see here
        https://github.com/sdetweil/MagicMirror_scripts

        remove or rename the MagicMirror folder to some other name
        the script assumes starting fresh

          Thank you! I think that solved that problem.

          Should the monitor that is connected (its connected via a microHDMI to HDMI and then an HDMI to DisplayPort adapter at the other end) automatically display once I’ve run pm2 start MagicMirror? Or do I need to take an additional step?

          It indicates process successfully started, however the monitor doesn’t show anything.
          I should note we’ve only ever ssh’d into the Pi from our desktops and I’ve never used a GUI connected to the Pi before, so very possible I’m not doing something correctly in that regard.

            @frosty_snow it should show, the startup sets the linux xwindows DISPLAY=:0

            unless there is another problem…

            do
            pm2 logs --lines=50

            pm2 status to show whats running

            pm2 stop all

            pm2 --help
            for more options

              Ok when I do pm2 status i do see that the status is “online” after I do the pm2 start MagicMirror. However yes it appears there is another issue, as my display simply remains blank (I’ve 3 screens, 2 connected to my desktop with the 3rd connected to the Rpi4).
              The log files show the following errors, which would seem its related to this line 102. Is it possible I need to edit this?

                @frosty_snow ok, that is my run-start.sh script which is put in in the case where electron won’t run …

                BUT it should start chromium-browser

                can u do

                which chromium 
                

                and

                which cromium-browser
                

                on a terminal window on the pi (or ssh session to the pi)

                because electron won’t run, we launch MM in server mode
                and then launch chrome over it…

                i had a case where the previous server mode was still running, and so I don’t have to tell u how to correct that, I kill it…

                pm2 job is to keep MM running… so, when the script ends, pm2 restarts it…
                over and over…

                oh by the way… the column on the pm2 status that looks like a circle with an arrow tip is the number of restarts… for your case at the moment, it should be going up

                  currently im only at 1 but it said 2 before i rebooted my pi
                  The below is the result of those cmds in the ssh session into the pi on my desktop

                  pi@raspberrypi:~ $ which chromium
                  pi@raspberrypi:~ $ which chromium-browser
                  /usr/bin/chromium-browser
                  pi@raspberrypi:~ $
                  

                  I’ve rebooted the pi before trying to start MM up again

                        I’d like to thank you so much for taking the time on this. I’ve figured out that it is a hardware issue. I switched up to a different monitor that is not display port and the MM is working correctly. I don’t know if its the Displayport that is the problem or not but I can use my other monitor for the actual MM build and just use this displayPort monitor as my secondary “reading” monitor.

                        Hope you have a lovely weekend and thank you again for working with me.
