Summary: click-drag and 2 finger scroll does not work on
Thinkpad T440
Product: Wayland

recording when clicking+dragging
libinput-1.10.7-1.fc28.x86_64; it's Fedora 28
I'm using Gnome with following settings:
- touchpad ON
- natural scrolling ON
- tap to click ON
- two finger scroll ON
- edge scroll ON
The hardware is Lenovo Thinkpad T440 with button-less touchpad (this was the
one year Lenovo fscked up and virtualized trackpoint buttons; they reverted
this change next year). The touchpad has markings for three virtual buttons at
the top. The touchpad moves down (towards inside of the computer; don't know
how to describe it precisely) during clicking.
THE PROBLEM:
1) click-and-drag doesn't work. When I push down, the click is registered. But
when I keep the finger down and start moving the finger over touchpad, the
mouse cursor doesn't move.
2) Two finger scrolling doesn't work at all.
Hopefully there's a trackpoint, so I can work around the problem using
trackpoint + virtual left button and trackpoint + virtual middle button (for
scrolling)

libinput measure trackpoint-range produces no output (apart from initial
banner)
There's no 'sensitivity' file anywhere in /sys/class/input
