[SOLVED]Fn keys broken after update

Hi,
After a system upgrade the fn keys controlling the keyboard backlight don't work. Other fn keys work fine

and Dmesg

[ 1053.214022] atkbd serio0: Use 'setkeycodes e017 <keycode>' to make it known.
[ 1053.455447] atkbd serio0: Unknown key pressed (translated set 2, code 0x96 on isa0060/serio0).
[ 1053.455455] atkbd serio0: Use 'setkeycodes e016 <keycode>' to make it known.

I can see what the issue is (somehow the update broke the keyboard "hooks"), but don't know how to fix it cleanly (with what to "hook" the keys).
Seems like a silly situation, so i start the thread in the newbies section.
thanks in advance

Re: [SOLVED]Fn keys broken after update

Hello, mpir, and welcome to Arch Linux forums.

Did you reboot after the kernel update? Did you deal with any and all the .pacnew files?
Is it by change the same issue as https://bbs.archlinux.org/viewtopic.php?id=169553 ?

When pasting configs, code or command output, please use [ code ] tags, not [ quote ] tags https://bbs.archlinux.org/help.php#bbcode

like this

It makes the code more readable and - in case of longer listings - more convenient to scroll through.

Re: [SOLVED]Fn keys broken after update

I did reboot and didn't deal with the .pacnew files.

I believe the solution has to do with "hooking" (what is the right word, btw?) these two fn keys with something inside /sys/class/leds/samsung::kbd_backlight, but it seems like a chaos inside there.

Re: [SOLVED]Fn keys broken after update

I know nothing about backlight, so I can only suggest searching (googling) around and reading the wiki https://wiki.archlinux.org/index.php/Backlight & https://wiki.archlinux.org/index.php/Ex … _scancodes

Re: [SOLVED]Fn keys broken after update

Solution:

prerequisites: xorg-xev

i) get the keyodes with dmesg | tail  {i used the eXX number, not the hex}

ii) test the scancode to keycode binding using

setkeycodes [scancode_you_found] [keycode] 

and then

xev

. You want your key to show up as "XF86KbdBrightnessUp/Down", my keycodes were 229 and 230

iii) make the change permanant by:

creating a new service

/etc/systemd/system/setkeycodes.service
[Unit]
Description=Change keycodes at boot

[Service]
Type=oneshot
ExecStart=/usr/bin/setkeycodes [scancode] [keycode]
ExecStart=/usr/bin/setkeycodes [scancode] [keycode]

[Install]
WantedBy=multi-user.target

and enabling the service

systemctl enable setkeycodes

cheers
