rough guess: you're not calling libinput_dispatch() when there's data on
the libinput_get_fd(). libinput doesn't work in a thread, it only does
things when you call libinput_dispatch() and that again may (or may not)
result in events being available.

IOW, unless you call libinput_dispatch(), nothing happens.

also - if in doubt enable debug logging so you can see what libinput
does during dispatch, that might provide some info too.
