Rotate your monitor

To rotate your monitor you'll need to add the following line to /boot/config.txt using the following command sudo nano /boot/config.txt

display_rotate=1

You can also set this value to '3' to have a flipped vertical orientation.

Disable screensaver and remove panel

Edit the /home/pi/.config/lxsession/LXDE-pi/autostart file with nano /home/pi/.config/lxsession/LXDE-pi/autostart.

Reccomended To disable the screensaver you'll want to comment out (with a '#') the @xscreensaver. You'll also want to add the following lines to that same file

@xset s off
@xset -dpms
@xset s noblank

Optional To remove the panel at the top of the screen to comment out the @lxpanel lines. If you want to be able to easily access the "menu" at the top of the screen do not do this step.

Hide the mouse when inactive

sudo apt-get install unclutter

Then Add unclutter -idle 0.1 -root to /etc/xdg/lxsession/LXDE-pi/autostart with sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
