Brightness Control Hotkeys not working on Debian 12, Lenovo IdeaPad3

[John Kerr Anderson]

Dear Debian Users:

I recently got a Lenovo IdeaPad3 with an Intel i5 1135G7 CPU with Iris XE
graphics. I can adjust the screen brightness by manually sliding the
controls in the quick settings at the top of the screen, but the hotkeys on
the keyboard do not work to adjust the screen brightness. The hotkeys do
work for adjusting audio, airplane mode, locking the screen and turning the
touchpad on or off.

Any easy way to get the brightness controls to work?

Here's the output from: inxi -SGMz

First thing is to check if any events are produced by the keys in question.
Try the 'xev' program from package 'x11-utils'.
