additional scripts that may be useful
the install has two sections of additional support I have provided those separately too, in case u need to run one separately, or changed your mind after install

turn off screen saver and setup pm2 to autostart MM on boot…
screensaveroff.sh, cut/paste this line into the terminal window on your device

bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/screensaveroff.sh)”

fixuppm2.sh, cut/paste this line into the terminal window on your device

bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)”

@peterpang Hi, you need to run the editor with root privileges “sudo vi …” or “sudo nano …”
