problem on the 19.10, the touchpad didn't work at all after resum from
suspend, i used to fix that calling

sudo rmmod i2c_hid
sudo modprobe i2c_hid

informations to solve the problem at its root?

Bug description:
  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.
