This has to do with switching to using evdev to handle input devices on 
FreeBSD 12 and CURRENT.  There's been several reports, and suggested 
solutions to this, as well as an UPDATING entry detailing the change.

I'm sorry that it has caused fallout, but it is something that needs to 
be done in order to keep up with upstream graphics stack, and to improve 
FreeBSD desktop support in general.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=196678 has some 
discussions regarding input devices, as does the x11_at_ mailing list archives.
