around that for now.

Title:
  Touchpad settings don't work after upgrading to 17.10 (because
  xserver-xorg-input-synaptics is still installed)

Status in gnome-control-center package in Ubuntu:
  In Progress
Status in gtk+3.0 package in Ubuntu:
  New
Status in mutter package in Ubuntu:
  In Progress

Bug description:
  Since upgrading to 17.10, my mouse pointer is repeatedly and
  frequently getting moved against my will when I am typing on my laptop
  keyboard (as opposed to external keyboard) because my hand brushes
  against the touchpad or even just near its surface.

  Furthermore, I don't want tap-to-click to be enabled. I want to
  actually have to push down on the mousepad hard enough to click it to
  generate a mouse button event. I can't figure out how to disable tap-
  to-click in 17.10 either.

  I did not have these problems _at all_ in 17.04.

  I have the touchpad click method set to "Areas" and "Disable While
  Typing" enabled in gnome-tweak-tool. This does not help.

  I have these lines in the touchpad section of
  /usr/share/X11/xorg.conf.d/40-libinput.conf as well:

  Option "DisableWhileTyping" "true"
  Option "PalmDetection" "true"
  Option "Tapping" "false"

  They don't help either.

  This is a substantial regression in functionality from 17.04.

  It appears to be a problem using both Wayland and Xorg.
