According to last -x command my session also terminates only when turning the screen back on. I also confirm that the session is not only logged out but every process created and all files in /run/shm/ are also killed. It seemed like installing caffeine (disabling auto suspend and screensaver) had solved it, but after turning the screen on in the morning the session crashed at that moment. In /var/crash there are files timestamped just after I turned the screen back on of: caffeine, Xwayland and gnome-shell. It's been hard to figure out a way around this bug. This was a fresh install of 17.10 on AMD cpu and AMD gfx card, HDMI monitor. Everything was updated before the latest crash occurred again.

A similar problem is described in two recent questions on AskUbuntu: https://askubuntu.com/questions/969376/how-to-keep-graphical-session- running-in-17-10-when-external-screen-is-turned-of https://askubuntu.com/questions/969510/ubuntu-17-10-logs-out-when- monitor-is-detached I could not find a related bug report to subscribe to so here I am. I would except the session to be available as if nothing had happened when I reconnect the screen, or at most that the session is locked (but still running). These are the system logs from when I tested it twice, at 00:26:50 and at 00:28:30.
