Sounds like you might have hit bug 1714330 but we should go though the
proper procedure in case you're experiencing a different problem...
Thank you for taking the time to report this bug and helping to make
Ubuntu better. However, your crash report is either missing or
challenging to deal with as a ".crash" file. Please follow these
instructions to have apport report a new bug about your crash that can
be dealt with by the automatic retracer.
If you are running the Ubuntu Stable Release you might need to enable
apport in /etc/default/apport and restart.
Now open your file manager, navigate to your /var/crash directory and open the
crash report you wish to submit.
If this fails you will have to open a terminal and file your report with
'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is
the crash you would like to report. If you get an error that you aren't allowed
to access this report you will have to file it with 'sudo ubuntu-bug
/var/crash/_my_crash_report.crash'.
I'm closing this bug report since the process outlined above will
automatically open a new bug report which can then dealt with more
efficiently. Thanks in advance for your cooperation and understanding.

Title:
Gnome-shell session crash after monitor switch-off/input change.
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
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.
