in the evemu recording log? we don't write that event to the device node, so
you shouldn't see that event except in the libinput debug log. If the event
comes up in the evemu log then we're dealing with a different issue here.

yeah, that's expected. when you're using the pen, you're likely to touch the
screen and cause fake pointer motion. This is called touch arbitration and an
explicit feature (used to be done in the kernel by some drivers). But that
obviously requires a working proximity out.

does the property show up in the udevadm info output and did you restart
libinput, like the link suggested? libinput should (internally) fake the event
after 50ms of inactivity, i.e. no events from the pen device.

meh, neither of us is a native english speaker, so...
