[SOLVED] Handle events for ACPI keys with udev rules

Good evening everyone!
Today I want to question you about handling ACPI events without acpid, but with bare system udev instead (writing rules).
I see that actually, when ACPI event occurs it first is hadled by udev (systemd-udevd process is spawned for a short time).

Basically speaking, is it possible to write udev rules for ACPI keys' events like lid opened/closed, power button, wlan key, mute and volume keys, brightness keys and monitor key?

Yeah, there are examples of that. I think acpid just makes the task slightly easier.

Re: [SOLVED] Handle events for ACPI keys with udev rules

Oh, I see that udev handles "power_supply" events ok (battery charge and discharge by 1%, AC on and off). But I see nothing for ACPI keys (lid, power button and all the others on the keyboard).

I have set "udev_log="debug"" in "udev.conf" file, but still I can't see them neither on system log nor on terminal with "udevadm monitor".
Where can I see them?

THANKS!

Man, I see nothing about ACPI keys in these examples, only other udev events. Thanks for the link however - now I know a bit more about what can be done with udev.

Unfortunately, I've had no luck in making udev respond to ACPI keys' events using udev rules. sad((

Only AC on/off and battery charge reporting seem to work with rules.
