Hello everybody.
Now I'm running Arch on my K751S laptop and the only issue that bothers me is function keys.
I've read quite a bit about this problem, tried different solutions, including asus_nb_wmi and acpi_osi, but nothing worked still.
Interesting fact that my function keys produce no scancodes in showkey (without X running), so I suspect some low-level problem with the kernel, probably wmi module in particular.
And I'm sure that these keys work, because when I run calculate linux live CD from my laptop they work "out of the box".
My wmi-related modules are:
$ lsmod | grep wmi
asus_nb_wmi 24576 0
asus_wmi 24576 1 asus_nb_wmi
mxm_wmi 16384 0
sparse_keymap 16384 1 asus_wmi
rfkill 20480 7 cfg80211,bluetooth,asus_wmi
video 36864 2 i915,asus_wmi
wmi 20480 2 mxm_wmi,asus_wmi
led_class 16384 4 ath9k,sdhci,input_leds,asus_wmi
Sound-related keys work fine (volume, mute). But all others are not.
Any ideas what I missed?

Solved.
It was really an acpi_osi issue, had to set it to
acpi_osi="!Windows 2012"
, configuring all proper acpi modules in /etc/modules-load.d and everything is fine. Though, I really want to know why disabling Windows 2012 acpi_osi treated like a "bad solution" (which I saw quite often while looking for answer) and what potential pitfalls it can produce.
Can anyone explain me that?
If someone will encounter the same issue, my configuration is:
Modules from acpi package:
ac
acpi_ipmi
acpi_pad
battery
bbswitch
button
fan
sbs
sbshc
thermal
video
WMI modules
lsmod | grep wmi
mxm_wmi 16384 0
asus_nb_wmi 24576 0
asus_wmi 24576 1 asus_nb_wmi
sparse_keymap 16384 1 asus_wmi
rfkill 20480 7 cfg80211,bluetooth,asus_wmi
wmi 16384 2 mxm_wmi,asus_wmi
video 36864 3 i915,int3406_thermal,asus_wmi
led_class 16384 4 ath9k,sdhci,input_leds,asus_wmi
GRUB config
cat /etc/default/grub | grep acpi
GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=\"!Windows 2012\""
