Adding this to *this* bug, despite the "Fix Released", because it
exactly  matches the original post for this bug, whereas the others I've
encountered and reported on are different:

Symptoms *observed*, again, were that I was logged out when I returned
to the computer the following afternoon.

So this happened twice in quick succession. The above fragment is from a
'grep gnome-shell syslog.1', I can provide a fuller log if anyone's
interested, but there was no /var/run/crash file generated from this
event.

  I'm testing Ubuntu 17.10 installed on Lenovo PC (with Intel Core
  i5-6500 CPU and Intel HD Graphics 530 (skylake GT2). Session is
  crashing (login screen is displayed again) every time I change the
  monitor Input (e.g. from DP to HDMI) or switching off the monitor. It
  is happening since some updated from beginning of September were
  installed. Same situation is for both session types, default Wayland
  and also for X.org. Tested also with Live USB, same behaviour.
