ACPI doesn't recognise Fn functionkeys, X (i3, xev) do! What can I do?
Hello,
I want to bind two of my FN-Functionkeys (F3/F4 = Keyboard Backlight Down/Up) to the corresponding function.
With i3 this is an easy task, "bindsym XF86KbgBrightnessDown exec asus-kbd-backlight down" works.
The problem is, that this works only within X and not in pure TTY console.
I read in the wiki about ACPI, this should do the trick also in pure TTY?
I installed it and tried to find the key name. The problem is that ACPI doesn't regognizs them!
"acpi_listen" says PNP0C14:00 / PNP0C14:00 / 000000ff 00000000
/var/log/messages contains "ACPI group/action undefined: PNP0C14:00 / 000000"
Is there something I can do?
Thanks!

okay, this sounds great, it would be one way to do it.
But I would be also interested in an ACPI solution. showkey -s in TTY shows "0xe0 0x58 0xe0 0xd8" and "0xe0 0x59 0xe0 0xd9" when I press the two Fn Keys.

Possibly try some of the acpi kernel parameters on boot up to see if that helps. For instance I read that the parameter "acpi_backlight=vendor" resolves some keyboard issues for changing the display brightness.
