Re: FreeBSD touchscreen support (xf86-input-evdev and xf86-input-libinput ignoring wmt device)

Answering my own question. This is already known:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=232040

Adding:

InputDevice "TouchScreen" "SendCoreEvents"

into "ServerLayout" section solve the problem, but
the drawback is that device name e.g. "/dev/input/event4"
in my case is hard-coded in a config file...

Regards,
Denis.
