# configure-kiosk.sh
#
# Author: dgrubb
# Date 05/26/2017
#
# Configures a fresh installation of Xubuntu to convert it into a kiosk which
# only runs a web application within Google Chrome. A user is created, named
# kiosk, whose account can only be accessed by automatically launching an X
# session (password is disabled). That X session doesn't include any desktop
# environment but instead runs Google Chrome in fullscreen kiosk mode.
#
# Usage: Launch as root (or with root permissions):
#   $ sudo ./configure-kiosk.sh
#
#   Tested on:
#
#       Xubuntu 17.04
#
# Other Ubuntu relatives will probably work fine, but I've only tested it on
# the above list.
