Setting up kiosk mode

First we'll set up our pi to boot into a slim window environment using X and Chrome so we can interact with DWC2, which we're going to install later, on.

Let's install some dependencies.

sudo apt-get install --no-install-recommends xserver-xorg x11-xserver-utils xinit xinput x11-utils openbox -y 
sudo apt-get install --no-install-recommends chromium-browser -y

Openbox is a window manager. It doesn't include any kind of menu or gui that you might expect with a normal desktop environment. This is good, we don't need it.

We'll need to edit /etc/xdg/openbox/autostart and replace it's contents with the snippet below.

# Disable any form of screen saver / screen blanking / power management
xset s off
xset s noblank
xset -dpms

# Allow quitting the X server with CTRL-ATL-Backspace
setxkbmap -option terminate:ctrl_alt_bksp

# Start Chromium in kiosk mode
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' ~/.config/chromium/'Local State'
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/; s/"exit_type":"[^"]\+"/"exit_type":"Normal"/' ~/.config/chromium/Default/Preferences
chromium-browser --disable-infobars --kiosk 'http://YOUR-IP:4750'

Please note, you need to edit it to match the IP address of your pi

Next you'll want to edit your ~/.bash_profile to include the line below.

[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && startx -- -nocursor

This is going to start X automatically when we log in. That in turn, will automatically launch chrome which we configured in the previous step.
