This script rotates the screen and touchscreen input, disables or enbles the touchpad, and dis- or enables the virtual keyboard on a Lenovo Yoga 13 or Yoga 2 Pro (source: http://askubuntu.com/q/405628/34298)

# This script rotates the screen and touchscreen input 90 degrees each time it is called,
# also disables the touchpad, and enables the virtual keyboard accordingly
