I honestly don't know what's happening here. both synaptics and libinput should
just support this without any further configuration out of the box. libinput
has some palm detection so that certain touches will be ignored while you're
using the trackpoint. but if both devices don't work then I don't know what's
going on here.

I recommend getting libinput from git and running the ./tools/event-debug
helper, you can easily gdb it to figure out where the events are disappearing
to, or what configuration isn't happy. run it with --verbose, that gives you
the software button state machine which may be enough to show what's going on
here.
