ACPI or other event for (physical) screen rotation on ThinkPad X220

Question

I have a ThinkPad X220 where one can flip the screen. I'd like to use the physical state of the laptop in a script, like letting ACPI or udev call the rotation script when I rotate the laptop.

How can I find out where the state of the laptop is exposed, if at all?

The states that I mean:

Just to check - is this possible on other OSs? – jackweirdy Apr 15 '13 at 19:05 — jackweirdy, Apr 15 '13 at 19:05
Never booted Windows on this one, so I have no idea. – Martin Ueding Apr 15 '13 at 19:19 — Martin Ueding, Apr 15 '13 at 19:19

I found this on the thinkpads forum. Relevant part of the script in the link:

rotation="$(xrandr -q --verbose | grep 'connected' | egrep -o  '\) 
(normal|left|inverted|right) \(' | egrep -o '(normal|left|inverted|right)')"

My think-rotate is based on this. But that only queries the current rotation state of the screen. It has nothing to do with the physical state of the screen. – Martin Ueding Apr 15 '13 at 17:06
Ok true, then please explain to me what you mean with "physical state". To me the physical state of the screen changes when -I- walk around the table (since the screen from my point of view turned up side down). – Rinzwind Apr 15 '13 at 17:11

He's looking for something that polls a sensor as opposed to the existent state. – RobotHumans Apr 19 '13 at 22:46
