0005 Description:
0006 This attribute returns a string with the current type-cover
0007 or device posture, as indicated by the embedded controller.
0008 Currently returned posture states are:
0009
0010 - "disconnected": The type-cover has been disconnected.
0011
0012 - "closed": The type-cover has been folded closed and lies on
0013 top of the display.
0014
0015 - "laptop": The type-cover is open and in laptop-mode, i.e.,
0016 ready for normal use.
0017
0018 - "folded-canvas": The type-cover has been folded back
0019 part-ways, but does not lie flush with the back side of the
0020 device. In general, this means that the kick-stand is used
0021 and extended atop of the cover.
0022
0023 - "folded-back": The type cover has been fully folded back and
0024 lies flush with the back side of the device.
0025
0026 - "<unknown>": The current state is unknown to the driver, for
0027 example due to newer as-of-yet unsupported hardware.
0028
0029 New states may be introduced with new hardware. Users therefore
0030 must not rely on this list of states being exhaustive and
0031 gracefully handle unknown states.
