In the beginning there was a keyboard. Then came the mouse. Then the touchpad, the mouse wheel, the trackpoint, the graphics tablet, the joystick, the touchscreen, the touchpad without buttons but with pressure, the pen tablet with touch, the joysticks with touchpads, the touchpad with trackpoints, the touch-capable mouse, gestures, … it all got rather complicated.

Over the last few years, we had a massive revamp of the input stack on our desktops. This talk is a tour starting with lowest levels of contemporary input devices and their common features and device types, going up through the intermediate levels where we add a lot of the software features (like buttons on a touchpad) to the new bits and pieces we’re adding to X and Wayland to support these features all the way to the application.
