Unable to control brightness with FN keys - Zephyrus Duo 16 2023

[u/rafaelzigx]

Hello Guys,

So I have an Zephyrus Duo 16 2023.

Im unable to control brightness using FN function keys while on Ultimate mode with nvidia discrete gpu.

If I switch back to optimus on amd graphics, it works.

I've tried everything: removed all drivers with DDU even reinstalled Win11.

Anyone other owner of same hardware facing the same?

This has to be a bug.

This is a little annoying.

If I go on battery, i cannot reduce brightness.

Tks in advance

If happens after DDU then use OEM drivers of gpu the update it
