I am currently running version 1.8.4-0ubuntu0.17.10.1 of both packages
and have not seen this problem for a while.  I have rebooted several
times since installing the packages.

Off-topic, but since yesterday (can't remember it happening earlier) I
have started seeing mouse button freezes after suspend and resume,
affecting clients.  Most windows can still be dragged, and the dock
responds to mouse buttons, but e.g. the terminal, Firefox and
Thunderbird respond to keyboard but not mouse.  I can raise the windows
using the dock.  Would you happen to know of any matching open bug for
that, or anything else?

Title:
  gnome-shell frozen and using 100% CPU after docking and display
  configuration change

Bug description:
  [Impact]

  I have been having regular system freezes after switching from using
  my laptop stand-alone to waking it up on a docking station with an
  external monitor. I have seen this using two identical docking station
  plus monitor combinations. I am still trying to find a pattern.  I was
  able to ssh in and use apport to save this bug information.  The
  gnome-shell process was hung at 100% CPU utilisation.

  libinput 1.8.4 fixes this

  [Test case]

  Wake up while the system is docked and attached to an external
  monitor.

  [Regression potential]

  The bugfix comes via a new microrelease update, so chance of
  regressions should be minimal.
