Bug Description

https://errors.ubuntu.com/problem/dcc31c919387fa75990e48e30880c3ec9bf46e18

---

This bug was collected by Apport and so I don't know all the details. I just installed Ubuntu 17.10 and I have had problems with all my programs being closed (it looks as if the computer had been rebooted) after the screen had been locked. I then changed from Wayland to Xorg, just before this bug was reported, but I am uncertain if the bug report pertains to this problem, or if the bug was for the Wayland or Xorg state. I'm happy to provide more information, I just need to know what to look for.
