    Greetings!
    I’ve tried multiple times with the same issue. My MM isn’t displaying on the 7" Pi touchscreen. Presumably it wants to display on the HDMI.
    When the pi boots I see the raspbian boot sequence on the touchscreen.

    Connected to Pi via ssh.
    Installed MM2 via script ‘bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)”’

    PM2 confirms a successful start of MM2. Nothing on the 7" touchscreen. Why would this be the case?

      @kindsouls the 7 in is not DISPLAY:0

      I have never seen or used one, so I don’t know what its display number is.

      change it in installers/mm.sh

        I thought so too, but then I ran tvservice:

        pi@raspberrypi:~ $ tvservice -l
        2 attached device(s), display ID’s are :
        Display Number 0, type Main LCD
        Display Number 2, type HDMI 0

            Raspbian lite, so no desktop, but I do see the
            “raspberrypi login:”
            after boot. I could hook up a keyboard and type on the screen I’m certain.
            I can also do things that effect the display in realtime, such as:

            sudo sh -c “echo 80 > /sys/class/backlight/rpi_backlight/brightness”
