@Aroenai said in Fresh RetroPie install on Debian 12 x86_64, keyboards not recognized in emulationstation:

Built From: Debian 12 net install (no GUI, installed to external USB 3.1 flashdrive) installation script from https://github.com/RetroPie/RetroPie-Setup

Actually now I noticed this - we don't support nor test running from the CLI on a PC, a desktop environment (X11/Wayland) is required on that platform.

If you still want to run it via KMS/DRM, check if your user is part of the input/video/render groups.

@Salaman64 thank you, the solution you posted worked for my samsung monitor with no HDMI input.

You don't really explain what's going on, but from what I can see, the display powers up, but you don't get any picture. I'm not sure it's the correct driver board, but if so, do you have to select the input with the side panel that you picked up and put down?
