I too have this issue, this affects anyone is is using Ubuntu with a TV if after watching something one line and you turn off the TV via remote, when the signal drops the Ubuntu sessions is terminated along with all running apps. My configuration is an Intel NUC with mini DVI to HDMI interface. This has only occured since upgrade from 17.04 to 17.10.

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.
