solved the problem! Brightness function keys started working properly in Ubuntu.

Hi @kai.heng.feng
Just updated BIOS and kernel. Unfortunately there are still no changes

Honestly, I thought that Ubuntu Team has capabilities to contact vendors

Hi @kai.heng.feng
No problem.
I tested "event04", logs below:

Additionally I tested "event16", but there was no reaction (doesn't
matter if using Fn + key combinations or when using Fn lock):
