/proc/acpi/button does not exist.

/proc/acpi/button does not exist. Any ideas?

or, anyone knows which module is the owner of /proc/acpi/button?

Thanks!

Not sure what you are looking for.

/proc/acpi/button does not exist

Is that an error from some process? You'll need to tell what you are doing.

Lets start with the outputs of:
uname -a
pacman -Qi linux
and
journalctl | grep dev/input

No. It's the reason the power button does not work.

I see you are running Graysky's Kernel. Graysky, if you happen by here, is there any reason the event system should not function?

Enihcam,
A couple more things. Could you check that the evdev module is running using lsmod | grep evdev
Do you have a /dev/input node in your file system? Is it populated?
Could you please post the contents of /proc/bus/input/devices

How difficult would it be to try this with a stock kernel?

I can try stock kernel, but maybe later because some tasks are running and cannot stop.
Thanks for your suggestion.

I am having the same problem, even with a stock kernel. There is no power button
device and therefore acpi_listen does not detect putton press events. I am on a
Thinkpad T420s, which used to work until a recent reinstall. Here are the
outputs that were originally requested (most of them look quite similar to
enicham's):

% lsmod | grep evdev
evdev                  11784  27

Did anyone ever resolve this issue? I am facing the same thing on a Surface Pro 3.

altercation · 2014-09-22 15:59:28

I wanted to note that at least in my case this has been filed and is now an active bug on the kernel bugtracker: https://bugzilla.kernel.org/show_bug.cgi?id=84651
