This will make it easier to figure > out what the ACPI code is doing. Sure, see attached (I hope gmail doesn't mess this up on me..) What makes me think it's not just an acpi issue is that the iio device doesn't seem to have an indicator for the rotation of hinge angle of the screen: ls /sys/bus/iio/devices/iio\:device0 buffer buffer0 current_timestamp_clock dev in_accel_hysteresis in_accel_offset in_accel_sampling_frequency in_accel_scale in_accel_x_raw in_accel_y_raw in_accel_z_raw name power scan_elements subsystem trigger uevent It is difficult to figure out if it's supposed to be the iio device that is supposed to make this happen - there's some talk of intel virtual buttons, but that seems wrong on an amd laptop and I don't see the necessary details in the dsdt table. Any idea on where the data is supposed to come from would also be helpful. The fact that it remains 0 after boot does seem to indicate that the device isn't writing anything to acpi - which fits with the missing module or module logic for whatever hardware is supposed to be doing this. I will say that the rotation of the display is detected and works, it's just the "laptop/tablet mode" that does not (0x60c0 is never emitted and so the keyboard and touchpad remain active). Although, I don't have a working screen rotating laptop, so I'm not entirely sure if that's necessary? > > Thanks, > Armin Wolf > > (Also, please do not top-post, thank you). > Sorry, I generally don't use gmail form development and haven't set up mutt for this address. Thank you for look at this issue. Thanks, Liam ...
