RetroPie X86 (linux) Detects Laptop Keyboard as Controller 1

[xboxiso]

RetroPie X86 (linux version) is detecting my Sony Vaio SVE1511RFXB keyboard as a controller connected to port 1. When I connect my Xbox 360 controller to the laptop it is assigned to port 2. The controller maps and works fine in the RetroPie menu, but does not function properly in game. At the moment the only emulator I'm using is RetroArch.

How can I get RetroPie to ignore the laptop keyboard and not assign it as a controller?

I have attached a photo of what my screen displays when I connect my Xbox 360 controller to my system when RetroPie is running. Thanks in advance for your help.

I love RetroPie, (I'm new to it) and hope I can get it working properly on this old laptop I'd like to re-purpose for gaming.

This looks promising. Thank you. I will try this.

I could be wrong, but this looks like it's specific to RetroPie on a rasberry pi. Does anyone know if this works on RetroPie X86 and how to install it on that platform?
