#!/bin/sh

# This script toggles between a 'normal' mode and a 'tablet' mode, doing
# a few things:

# - rotates the screen using =xrandr=, so that rotating the physical
#   display of my X220t would have the laptop's battery on the right
#   hand side,
# - enables touch screen,
# - properly rotates the stylus pen and touch screen pointers, and
# - toggles between RGB and Vertical BGR sub-pixel order.
