Changes are applied on the list of devices and the corresponding cases which include my devices.
By devices I mean the finger touch for example
TouchscreenDevice='Wacom ISDv4 E6 Finger touch'
It could be different in your case. This script in my case is x220t.

The onboard settings you're asking about are related to this thread https://bugs.launchpad.net/ubuntu/+source/onboard/+bug/1297692

Basically, there are issues on making finger touch working on when by default the stylus is the one listened two, that's why I play turn on/off finger and onboard

Possible you want to add:

TouchscreenPenEraserDevice='Wacom ISDv4 E6 Pen eraser'

With:

xinput set-prop "$TouchscreenPenEraserDevice" 'Coordinate Transformation Matrix' $inverted
...$left ...$right ...$normal

in the if, elif and else blocks.

Feel free to fork ;)

Hi I did ur rotate screen script on my lenovo x220. Now my screen is upside down. How do I remove your script?

To remove the script, remove the rotate-screen.sh file you executed.

I did that and screen still upside down

Im trying to get it back like i never executed the script cuz my screen is stuck upside down and the touch is working weird probably due to the script

How do i put everything back to normal as if i never did the script?

Just restart your computer and the state of the system will be as if you never executed the script

it for some reason stays like that even after reboot or shut down
I was able to go in to system settings display and change the screen to normal now its correct, but im worried about the other changes?

Well, the script is open source and you see all the contents - nothing is hidden. Follow the logic, break it down or understand it, if necessary, change it, run it, etc.

I had no luck, but I was able to get to system settings and go to display and change settings now screen is no longer upside down, are there any other changes from the script I need to change? Thanks Ray
