[SOLVED] External Keyboard (iqunix) F keys not working

I've noticed the other day that my F keys are not working as expected.
This was not the case before, I'm not completely sure when the issue started, but I'll assume less than one week ago.

I've tried to check `showkey` and pressing the F-keys gives the wrong keycode (which does not necessarily coincide with what I get by pressing Fn+F#)
The behaviour of Fn+F# it's still correct, but somehow I don't have access to any of the F-keys.

So far I was able to check my keyboard only on another device, my phone, and there the F-keys are working.
I've also tried to open a TTY terminal before loading gnome, but also in that case the F-keys are not working.
Using another keyboard at work worked just fine, restricting somehow the problem to just the iqunix keyboard.
The problem persisted in both Bluetooth and wired mode.

Since this is a fairly recent problem, I'm assuming that it's due to some recent software update and not a keyboard issue.
The manual for the keyboard has no mention of any fnlock, so I would exclude that. 

I'm completely clueless on where to look next, or even how to approach the problem. Any hint or suggestion is very welcomed.


running `loginctl show-session 3 -p Type` gives 

Type=x11

Re: [SOLVED] External Keyboard (iqunix) F keys not working

was not the case before … showkey

The cause is likely either the kernel or systemd (udev) - can you reproduce it w/ the LTS kernel?

pressing the F-keys gives the wrong keycode

How wrong? (What codes in particular?)

This may be it!
I'll try to change the kernel, if I don't report anytime soon it means that I did something wrong

Re: [SOLVED] External Keyboard (iqunix) F keys not working

Looks like some bogus Fn-lock still.
If it's not the kernel, the cause is likely in /usr/lib/udev/hwdb.d/ and likely 60-keyboard.hwdb

Re: [SOLVED] External Keyboard (iqunix) F keys not working

Now it works perfectly using

Kernel: 5.10.67-1-lts

Where should I report this problem?
I'm still wondering why it was happening only with one keyboard.
I've tried to obtain the raw input from my keyboard, but all I could get is the output of /dev/input/event and showkey with already the wrong encoding.

More details:
I've installed linux-lts and linux-lts-headers, and added a new entry to `/boot/loader/entries/

/boot/loader/entries/arch-lts.conf
-------------------------------------
title Arch Linux LTS
linux /vmlinuz-linux-lts
initrd /initramfs-linux-lts.img
options cryptdevice=UUID="4f2ae368-9581-420d-b8d5-a07f8a4b6aa0":luks_root root=/dev/mapper/luks_root quiet rw

and then run `sudo bootctl update`

Re: [SOLVED] External Keyboard (iqunix) F keys not working

Some wmi modules have an Fn parameter… since you stress "external" I guess this is a notebook?

lsmod

Ok, this was quite a journey... I manly got lost into looking at the differences between 5.14.6 and 5.10.67 on https://www.kernel.org/

In the meantime I've also run `sudo dmesg -w` to see which driver I was loading. By disconnecting and reconnecting my keyboard I've got:

[ 1323.483167] apple 0005:05AC:024F.0001: input,hidraw0: BLUETOOTH HID v0.01 Keyboard [iQunix F96 KB 1] on 1c:4d:70:24:2a:7e

when doing the same with the LTS kernel, it shows that the driver used is `hid-generic`.
After more clules wondering I finally looked into "module.alias" for the two versions and I found the problem

/lib/modules/5.14.6-arch1-1/modules.alias
-------------------------------------------------
...
alias hid:b0005g*v000005ACp0000024F hid_apple
alias hid:b0003g*v000005ACp0000024F hid_apple
...
/lib/modules/5.10.67-1-lts/modules.alias
-------------------------------------------------
...
alias hid:b0003g*v000005ACp0000024F hid_apple
...

Now the b0005 is for Bluetooth  while b0003 is for the USB connection (at least for me)
So the problem is solved by running 

rmmod hid_apple

I'm not sure if there is a more elegant way

Re: [SOLVED] External Keyboard (iqunix) F keys not working

Made the removal of hid-apple permanent following https://wiki.archlinux.org/title/Kernel … acklisting

/etc/modprobe.d/blacklist.conf
-------------------------------------
# Do not load hid-apple on boot
blacklist hid-apple
