#!/usr/bin/env sh

# rotate_desktop.sh
#
# Rotates modern Linux desktop screen and input devices to match. Handy for
# convertible notebooks. Call this script from panel launchers, keyboard
# shortcuts, or touch gesture bindings (xSwipe, touchegg, etc.).
#
# Using transformation matrix bits taken from:
#   https://wiki.ubuntu.com/X/InputCoordinateTransformation
#
# Forked from https://gist.github.com/mildmojo/48e9025070a2ba40795c
# Configured to use with a Lenovo Yoga 260 (names taken from `xinput` output).
# If the rotation position ($1) is ommited, the script toggles through the different states: inverted, left, right, normal
