I open the File Manager , then open the " boot " folder , then click into the " cmdline.txt , see there’s a text :
" console=serial0,115200 console=tty1 root=PARTUUID=7e583fb6-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles "
add “consoleblank=0” here ? add in the first place or where else ?
sorry , I’m just a very very Beginner , the first time in writing progamme

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 …”
