--- Comment #1 from Jean-Sébastien Pédron <dumbbell at FreeBSD.org> ---
Hi!

I tried your patch + drm-next and it's working quite nicely!

I used xf86-input-libinput to drive a Synaptics touchpad (Thinkpad T440p) and
an external USB mouse, and xf86-input-evdev to drive the internal keyboard of
the laptop and an external USB keyboard.

I couldn't get the keyboard to work with xf86-input-libinput, even though
correct events are reported by libinput-debug-events(1). With xf86-input-evdev,
it looks ok, though with the internal keyboard, the "less than/greater than"
key doesn't emit any event. I didn't check if the same issue exists with the
external keyboard. They are a few other bugs with the touchpad as well, but
it's still better than without libinput.

I don't know if it was necessary, but I added InputClass blocks to ignore other
devices, like duplicates (/dev/{psm,sysmouse,atkbd,kbdmux}* vs /dev/event/*).
