sudo apt update
sudo apt upgrade -y
#add following line to the file /etc/xdg/lxsession/LXDE-pi/autostart or /home/pi/.config/lxsession/LXDE-pi/autostart
@chromium-browser --start-fullscreen --kiosk URL 
#some people suggest to use files /etc/xdg/lxsession/LXDE /autostart or /home/pi/.config/lxsession/LXDE /autostart
# which does not work for me (as seems they are not for “pi” user)
#Options:
#”--kiosk" option – hides “F11 to full screen” message, but to exit from the browser - hit Alt+F4
#instead of specifying the URL in the autostart file – add the URL as a home startup page
#Disable Swap 
sudo dphys-swapfile swapoff && \
sudo dphys-swapfile uninstall && \
sudo systemctl disable dphys-swapfile
#disable scree saving
xset s 0
xset -dpms
#validation:
xset q
#or install a screensaver and in the System Preferences/Screensaver – turn it off
sudo apt install xscreensaver
# To remove a black border around the display – in the /boot/config.txt file uncomment disable_overscan=1 and set negative numbers in overscan_left, overscan_right, etc and restart the RPi
sudo nano /boot/config.txt
disable_overscan=1
