Ubuntu developers working on Mir have been making measurable progress recently on using libinput for their input handling, similar to Wayland and in the X.Org world where libinput is also being used via the xf86-input-libinput driver.

We've been looking forward to Mir working towards libinput and with the latest Bazaar repository work they're indeed getting there: installing libinput as a driver package, adding input-evdev.so based on libinput to replace InputReader, EventHub, and InputMappers, etc.

The libinput platform though isn't yet utilized by default. At least though Canonical didn't fork libinput and are working into the right direction.
