The Input Stack on Linux – An End-To-End Architecture Overview

Exposed layer (middle)

User-space handling:

The Widgets, #XServer, #X11 window managers, and #Wayland compositors, which rely on everything else

We’ll try to make sense of all this, one thing at a time, with a logical and coherent approach.""

After the parser is done, my plan is to write a validator that uses data from #trbot to map the inputs to buttons and axes on virtual devices.

Before starting this, I already took a dive to refine my #rust skills by writing native virtual devices using #evdev-rs that can be plugged into TRBot at a later time: https://codeberg.org/kimimaru/UinputVirtualDevices

I have yet to implement the wrapper for vJoy, but I'll be prioritizing uinput and #gnu / #linux as that's what I use and run my Twitch Plays streams on.

New humble project: EMD (Event Mapping Daemon)
https://github.com/lonequantum/emd
Have a look at it if you want a simple solution to map events (a particular key pressed, for example) to shell commands.

#Linux #streamdeck support, in C, as it should be. Injects key presses #evdev #uinput

Static keys, icons and it is ugly and mainly just a test for now.

Maybe it will evolve, who knows. Anyway here you go: https://github.com/oniongarlic/sdeck

Steam / most importantly a LINUX gamer with a Steam Controller?

The excellent SC Controller project adds Bluetooth support!

SC Controller is a Driver and user interface for working with the Steam Controller.

Version 0.4.3: Steam Controller, the Sony Dualshock 4 (PS4 gamepad) and all other Bluetooth pads recognized by evdev (a generic input event interface in the Linux kernel) are now supported.
