XF86 keys on asus keyboard

Hello,

I was trying to set-up arch on a new asus laptop, I was binding my Fn keys and I remarked the backlight keys are not working (ie. X does not receives any event when I run xev).

I dig a little and found there is a kernel module "asus_laptop".

modinfo asus_laptop

filename:       /lib/modules/4.1.6-1-ARCH/kernel/drivers/platform/x86/asus-laptop.ko.gz
license:        GPL
description:    Asus Laptop Support
author:         Julien Lerouge, Karol Kozimor, Corentin Chary
alias:          acpi*:ATK0101:*
alias:          acpi*:ATK0100:*
depends:        sparse-keymap,input-polldev,led-class,rfkill
...
...

but when I try to add it :

sudo modprobe asus_laptop

I get :

modprobe: ERROR: could not insert 'asus_laptop': No such device

I googled the problem extensively and some people says it's a bug (there is a bug report on this for redhat) but some people say it is a acpi only module and cannot be loaded.

I hope you will be able to help me.

Re: XF86 keys on asus keyboard

You should name the exact model, there are so many Asus machines. What works definetely depends on the model.
I know there are different modules, maybe another one is autodetected? for example "asus-nb-wmi". If yes, have a try to boot with the "acpi_osi=" kernel parameter.

Re: XF86 keys on asus keyboard

Hello,

Thank you for your answer, The exact model is ASUS BU401LG-FA123G . I already have asus-nb-wmi enabled and I tried setting acpi_osi=Linux in /boot/loader/entries/arch.conf in the option line. And still have the problem.

Thank you,
