I'm currently using a Dell Inspiron 5482 2-in-1 laptop. I can detect the hinge movement (kind of), but it's ambiguous.
When the hinge goes from 'laptop' mode to 'folded' mode (where the angle between the screen and the keyboard is more than 180 degrees, but it's not folded completely flat), it sends two presses of keycode 240 (according to showkey --keycodes).
When the hinge goes from 'folded' to 'tablet' (fully flipped around), it sends the same two presses of 240. When moving the other direction, it sends the same thing. I was wondering if there is anywhere that I could poke around to find a difference? I've already tried:
evtest
(nothing)
xev
(inconsistent)
acpi_listen
(doesn't show any difference between directions or actions)
dmesg -wH
(This does show a difference, but I have no clue how to listen to dmesg events in a shell script)
For reference, the output of
dmesg -wH
When changing from 'laptop' to 'folded':
