Hello @randomCharacter ,

I have added your configuration. Can you install and give me a feedback? If I remember well, there is a problem with the M15X series.

Best regards,

Hi @rsm-gh,
Thank you for fast response. The provided link is redirecting to issues, but I assume you are referring to this commit. After running setup, my laptop was detected as Aleinware15R4, instead of AlienwareM15R4, but both configurations didn't work at the end.

@randomCharacter ,

but I assume you are referring to this commit.

Yes that's the commit, my mistake !

After running setup, my laptop was detected as Aleinware15R4

The ID of that keyboard is pretty common so actually you can select a ton of different configurations. Never the less, when installing the software, you should select the AlienwareM14R4

but both configurations didn't work at the end.

Sadly that's what I was expecting. For making work your computer I need to fix this issue, the problem is currently affecting (at least) the M15R1,2,3,4, and the 15R1.

To be honest I don't have the hardware for doing it since I only posses on M14XR1. I doubt that I'll fix it but if someday it is done you will be able to benefit.

Best regards,
rsm

I see.
Thank you for maintaining this project. I'll look into your code myself, so maybe I'll be able to help with this.
Also I noticed that AKBL only supports setting colours on specific zones, but my laptop has per-key lighting keyboard. Will setting zones work in this case or is the keyboard using different controller?
