--- Comment #22 from George (george.stafilidis@proton.me) ---
Thank you for the explanation and for your patience. I have attached
(dump_off.txt,dump_low.txt,dump_high.txt and dmesg_ec.txt) I hope i did it
correctly.


I did try the unmodified patch and from what i can see the GNOME Quick Settings
panel correctly displays all three states (Off, Low, High) but dotes not change
the brightness of they keyboard. Pressing Fn + Space correctly triggers the OSD
notification. i could upload a video if that's possible to show you what I can
see. (is it possible to upload mp4?)
