I already did what you asked me.

Adrian:

1) Is this something that stopped working after an update? If so, which and when precisely?

2) Could you please provide the missing information from https://wiki.ubuntu.com/Kernel/Debugging/Backlight ?

[Adrian (adrirey93)]

1-in previous versions if it worked, install ubuntu 18 and it does not work.
2-I'm on it

Brightness and other custom keybindings are the responsibility of the kernel. Although in some cases a BIOS update helps too.
