1 What: /sys/bus/surface_aggregator/devices/01:0e:01:00:01/state 2 Date: July 2022 3 KernelVersion: 5.20 4 Contact: Maximilian Luz <luzmaximilian@gmail.com> 5 Description: 6 This attribute returns a string with the current type-cover 7 or device posture, as indicated by the embedded controller. 8 Currently returned posture states are: 9 10 - "disconnected": The type-cover has been disconnected. 11 12 - "closed": The type-cover has been folded closed and lies on 13 top of the display. 14 15 - "laptop": The type-cover is open and in laptop-mode, i.e., 16 ready for normal use. 17 18 - "folded-canvas": The type-cover has been folded back 19 part-ways, but does not lie flush with the back side of the 20 device. In general, this means that the kick-stand is used 21 and extended atop of the cover. 22 23 - "folded-back": The type cover has been fully folded back and 24 lies flush with the back side of the device. 25 26 - "<unknown>": The current state is unknown to the driver, for 27 example due to newer as-of-yet unsupported hardware. 28 29 New states may be introduced with new hardware. Users therefore 30 must not rely on this list of states being exhaustive and 31 gracefully handle unknown states. 32 33 What: /sys/bus/surface_aggregator/devices/01:26:01:00:01/state 34 Date: July 2022 35 KernelVersion: 5.20 36 Contact: Maximilian Luz <luzmaximilian@gmail.com> 37 Description: 38 This attribute returns a string with the current device posture, as indicated by the embedded controller. Currently 39 returned posture states are: 40 41 - "closed": The lid of the device is closed. 42 43 - "laptop": The lid of the device is opened and the device 44 operates as a normal laptop. 45 46 - "slate": The screen covers the keyboard or has been flipped 47 back and the device operates mainly based on touch input. 48 49 - "tablet": The device operates as tablet and exclusively 50 relies on touch input (or external peripherals). 51 52 - "<unknown>": The current state is unknown to the driver, for 53 example due to newer as-of-yet unsupported hardware. 54 55 New states may be introduced with new hardware. Users therefore 56 must not rely on this list of states being exhaustive and 57 gracefully handle unknown states.
