Hi, I am using a HP Pavillion 15-cx0598na.
I am having trouble getting my brightness keys to be registered. It
should also be noted that my wireless toggle key does not work either -
I assume that is a seperate issue as it is handled by a different
module.
Nothing is detected through acpi_listen, xev or showkey. However, in
the journal I get this error (same when pressing both keys):
```
Apr 26 15:50:05 archlinux-laptop kernel: atkbd serio0: Unknown key
pressed (translated set 2, code 0xab on isa0060/serio0).
Apr 26 15:50:05 archlinux-laptop kernel: atkbd serio0: Use 'setkeycodes
e02b <keycode>' to make it known.
```
Here is a link to acpidump: https://termbin.com/2l2x
I have already tried to contact the author of `hp_wmi` (the module for
handling some hotkeys) but he could not solve the issue so suggested
contacting this email.
Yours Sincerely,
Rhys Perry
