# 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 | |
# | |
# Configure these to match your hardware (names taken from `xinput` output). | |
