    Seriously? I am currently using Dell Inspiron i3583 and I am using windows currently. I have not seen this feature anywhere. I was thinking about moving to Linux due to some work. Can you please guide me where this feature is in windows?

    Simple trick: laptop can only be unlocked when the lid is half open. Perfect security! Who would think of that?

    So many great comments in this thead.

    Interesting.

    Funnily enough, my old Lenovo Yoga 2 Pro autodetects the screen position (landscape/portrait and laptop/tablet position)... the laptop/tablet thing needs Windows to work correctly (and switched between "desktop" Windows 8.1 and "tablet mode" Windows 8.1) but the landscape/portrait detection appeared to be completely independent of OS, as it worked in both Linux and Windows. I also remember shutting it down once in "tablet portrait" mode, and it displaying the Lenovo logo in portrait mode when I turned it back on later... but to be honest I have no idea whether that was correct or not, as Windows loaded in laptop/landscape mode.

    This is great - now I don't need to carry a laptop AND a speed square everywhere...



    Looking forward to the first HingeMark numbers.

    Ever seen people at conferences? Sometimes, they have their lid half closed for whatever reasons they have; but they usually do so because angle=0 would trigger the default suspend action, and they don't want that. But since text is hard to read at angle=45, you could, now that you know the exact angle and not just two states, turn off the screen at angle 45 and still have suspend with angle 0.

    The accelerometer only tells you acceleration and/or the tilt of the keyboard relative to gravity (angle between keyboard and ground), which is, mathematically, something completely different than angle between screen and keyboard. Also, no net gravity in space or the Vomit Comet airplane (they do use laptops there).

    For fall detection, you need an accelerometer, not a potentiometer (which is what the hinge angle mechanism probably uses).

    Perhaps there is an education use-case: you can now use your laptop to measure angles.

    Those laptops that have different modes based on how you position/swivel the display. Such as changing from a desktop to tablet UX.

    My laptop turns off the display at a near closed angle, as someone else mentions this is handled by the BIOS probably, but with this driver your system could respond to that event and do something if you wanted it to (turn off wifi or other things maybe if it's not supporting S3/suspend? switch to powersave profiles, etc).

    If it works in Windows, then I expect it to work in Linux.
