Script to rotate the screen and touch devices on modern Linux desktops. Great for convertible laptops.
#!/bin/bash
#
# 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
#
# Configure these to match your hardware (names taken from `xinput` output).

@V-VR You can assign custom keyboard shortcuts in Mint's Keyboard settings. I have four of them set up, using Ctrl + Alt + Super + to manually set the screen and touchpad orientation by calling this script.

For instance, one of my custom shortcuts is called "Rotate desktop left", assigned to Ctrl + Alt + Super + Right (because the bottom of the screen will be to the right after "rotating" to the left), and it calls /home/mildmojo/bin/rotate_desktop.sh left.

@V-VR: You can also head to the rotate script at linux-surface for a semi-automatic rotation script: If you follow the Installation there you get an icon in your panel. Whenever you rotated the Surface, you click on that icon and the screen adjusts automatically to the new rotation.

@V-VR I have created some .desktop files here to manually select your rotation. I had to change one variable in my system.
