What: /sys/bus/surface_aggregator/devices/01:0e:01:00:01/state
Date: July 2022
KernelVersion: 5.20
Contact: Maximilian Luz <luzmaximilian@gmail.com>
Description:
This attribute returns a string with the current type-cover
or device posture, as indicated by the embedded controller.
Currently returned posture states are:
- "disconnected": The type-cover has been disconnected.
- "closed": The type-cover has been folded closed and lies on
top of the display.
- "laptop": The type-cover is open and in laptop-mode, i.e.,
ready for normal use.
- "folded-canvas": The type-cover has been folded back
part-ways, but does not lie flush with the back side of the
device. In general, this means that the kick-stand is used
and extended atop of the cover.
- "folded-back": The type cover has been fully folded back and
lies flush with the back side of the device.
- "<unknown>": The current state is unknown to the driver, for
example due to newer as-of-yet unsupported hardware.
New states may be introduced with new hardware. Users therefore
must not rely on this list of states being exhaustive and
gracefully handle unknown states.

Description:
This attribute returns a string with the current device posture, as indicated by the embedded controller. Currently
returned posture states are:
- "closed": The lid of the device is closed.
- "laptop": The lid of the device is opened and the device
operates as a normal laptop.
- "slate": The screen covers the keyboard or has been flipped
back and the device operates mainly based on touch input.
- "tablet": The device operates as tablet and exclusively
relies on touch input (or external peripherals).
- "<unknown>": The current state is unknown to the driver, for
example due to newer as-of-yet unsupported hardware.
New states may be introduced with new hardware. Users therefore
must not rely on this list of states being exhaustive and
gracefully handle unknown states.
