@Atahan use the pm2 tool to autostart on boot…

if u did not set this up during install, then use my script

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

make sure u set the pi to autologon to the desktop at boot (using raspi-config)

Yes, always is a good idea to make a backup of a file before modified it :winking_face:
