Write a single library to handle all input devices, it'll be easy they said...
summary
A single C library called libinput is presented as the unified input backend used by all major Wayland compositors and the default X.org input driver (Fedora switched in 2016); it replaces multiple legacy drivers with one stack, an X driver wrapper xf86-input-libinput, and a quirks database of device fixes. It handles mice, touchpads, tablets and touchscreens (not joysticks), implements seven palm-detection methods, normalizes units, reduces per-user configs, and works but suffers a low-maintenance bus factor and some missing legacy features.
