Hi, Dmitry, I have a question about the ACPI lid button input device. By reading commit c0968f0e, I think the acpi lid button is registered as a switch (EV_SW set), and the lid status is reported via SW_LID bit, e.g. lid closed when SW_LID is set and vice versa. Then we update the lid switch status when a Lid notification comes. right? Then, IMO, userspace can get the lid status via /sys/class/input/inputX/uevent, right? here is a the output of this file on my laptop, /sys/class/input/input1/modalias:input:b0019v0000p0005e0000-e0,5,kramlsfw0, /sys/class/input/input1/name:Lid Switch /sys/class/input/input1/phys:PNP0C0D/button/input0 /sys/class/input/input1/uevent:PRODUCT=19/0/5/0 /sys/class/input/input1/uevent:NAME="Lid Switch" /sys/class/input/input1/uevent:PHYS="PNP0C0D/button/input0" /sys/class/input/input1/uevent:EV==21 /sys/class/input/input1/uevent:SW==1 /sys/class/input/input1/uevent:MODALIAS=input:b0019v0000p0005e0000-e0,5,kramlsfw0, Lid is opened but SW is set, I tried to close/open the lid and found that this bit never changes. is there something I misunderstand? can we get the lid status in userspace? thanks, rui -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
