Comment 281 for bug 1810183

Hi guys,

I'm pretty new to linux (finally decided to get rid of windows after many years). I'm runnig on Ubuntu 21.10 now...

I have Asus Zenbook 14 UX431DA which originally came with standard touchpad with fingerprint
sensor. So I decided to buy numpad mod hardware piece for my notebook. Succesfully installed yesterday, also did install driver package. Everything is working correctly but without backlight.
When I press the numlock button on it, I can type the numbers and symbols, but I'm not able to toggle the brightness (backlight), so I don't see anything on the touchpad.
As I am working a lot in excel I really need to get a numpad working properly. So I hope that somebody could help me with this.
Thanks, Zee
