        Hey @sdetweil , no problem at all - no rush indeed. Thank you for your help thus far.

        So thanks to this page I have been able to run up two chromiums, one on each page but I have started up chromium directly via terminal from the desktop. Not quite figured out how to implement this as two MM’s and if running up two at once would kill the CPU.

        raspberrypi.org forum post

        1st terminal session

        DISPLAY=:0 /usr/bin/chromium-browser \
        --noerrdialogs \
        --kiosk \
        --window-position=0,0 \
        --start-fullscreen \
        --user-data-dir=Default
        

        2nd terminal session

        DISPLAY=:0 /usr/bin/chromium-browser \
        --noerrdialogs \
        --kiosk \
        --window-position=1920,0 \
        --start-fullscreen \
        --user-data-dir=‘Test2’

          @NathTheDude copy one MM folder tree to MagicMirror1

          then change the config on MM1 to use a different port (8081 maybe)

          then start both MM in serverOnly mode (u can set that in config.js too, serverOnly: true,

          then launch your two browsers, with the url pointing to separate MM’s…
          –app=http://localhost:MM_port,
          –app=http://localhost:MM1_port

          you can edit the run-start.sh on MM1 to add the

          --window-position=1920,0 \
          --user-data-dir=‘Test2’
          

          parms to the ones already provided

          then change both MM configs to serverOnly: “local”,
          and it will launch the chrome browser for you
          (this is what we call split mode, using a separate browser)

          then u can have pm2 start both of those when the system boots…
          have to change the mm.sh in MM1/installers, and maybe the json file title to MagicMirror1, and point to the local mm.sh

            Hey @sdetweil , thanks for the info on this - I am grateful.

            I think I am nearly there but just missing a bit or two.

            I copied the ‘MagicMirror’ to ‘MagicMirror2’ folder, updated the config.js, run-start.sh and the pm2_MagicMirror.json files.

            When I reboot I now get MM and MM2 load up but both on the same screen.

            I have messed around with the chromium line from the ‘run-start.sh’ and I don’t think it is actually be used in this case, I even commented the line out and this did not prevent me from running ‘npm start’ and MM2 still loaded albeit on top of the first MM.

            Any ideas on where it is getting it’s info on how to start up chromium?

            Thanks

            Nathan

              @NathTheDude sorry. I left out the pm2 steps

              From mm2 folder do

              pm2 start installers/pm2???.json
              pm2 save
              

              Where the json file is the one u modified.

              It should start the second mirror app.

              The only difference is that window-positio info. And on reboot

              pm2 status should show both.

              Can u show the two chromium browser lines?

              I will attempt to recreate here

                Hey @sdetweil , after looking at how the current MM is setup with pm2 (pm2 show MagicMirror) this had the ‘mm.sh’ as the target.

                Within the MM2 folder I ran: ‘pm2 start ./installers/mm.sh --name MagicMirror2’ which started the MM2 but on the first screen. Then used pm2 save.

                I just setup pm2 with the .json file instead of the mm.sh file and the results seem to be the same from what i can see with it getting displayed on the first screen.

                Within the start-run.sh, I can comment out the chromium line and and it will not break anything which makes me think this line is not being referenced.

                MM line:

                chromium-browser --noerrdialogs --kiosk --user-data-dir='Default' --window-position=0,0 --disable-infobars --app=http://localhost:$port  --ignore-certificate-errors-spki-list --ignore-ssl-errors --ignore-certificate-errors 2>/dev/null
                

                MM2 line:

                chromium-browser --noerrdialogs --kiosk  --disable-infobars --app=http://localhost:8082 --ignore-certificate-errors-spki-list --ignore-ssl-errors --ignore-certificate-errors --window-postion=1920,0 --user-data-dir='Test2' 2>/dev/null

                  @NathTheDude if u start the json file, pm2 reads the info, gives u a nice name etc.

                  pm2 delete 0 or 1
                  pm2 save

                  Then pm2 start the json file.
                  And pm2 save
                  To save for reboot

                    I was able to recreate the problem, and good news its just a typo

                    --window-postion=1920,0
                    

                    should be

                    --window-position=1920,0
                    

                    missing i in position

                      Thank you for this although it is still producing 2 x MM’s on the first screen (MM and MM2), not sure what could be wrong. If you have it working it obviously must me something I have done wrong…hmmmmm.

                      I will review all the files and let you know if I find anything.
