Lenovo Yoga 3 Pro rotate script for linux

TouchscreenDevice='ATML1000:00 03EB:8A10'
TouchpadDevice='SYNA2B22:00 06CB:2714'

These are the settings for my lenovo yoga 3 pro. If this is not working for you, find your Touchscreen and Touchpad device with xinput.

# 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

  1. Thank you for sharing this informative and educational article. I have also shared it on my blog, where I discuss slippers designed to help relieve heel pain. This post aroused my curiosity a lot I am watching phd thesis writing. It holds a lot of curiosity for me. By the way, I came across this post while looking for information on a blog search. Keep up the good work - your posts are informative and helpful.
