Public bug reported:
I own a Thinkpad T440p onto which I have had Debian 9 running without
hardware issues. I have recently installed Ubuntu 17.10 final beta to
test it out, but two-finger scrolling does not work at the moment. It
used to work out-of-the-box from the final beta iso, but a subsequent
update broke it.
