Public bug reported: I am using Ubuntu 18.04 (Bionic) 64-bit on a System76 Galaga UltraPro laptop. At work, I plug two displays into my laptop, one DisplayPort and one HDMI.
If, while both displays are plugged in and the laptop lid is closed and the laptop's built-in display is therefore disabled, I: 1. lock my screen; 2. unplug both displays at about the same time; 3. wait about ten seconds; and then 4. open my laptop lid, I find that I have been logged out. If I immediately log back in to the built-in display, a couple seconds after I log in, the screen locks. If I then immediately log out and log back in again, the screen does _not_ lock. It seems that this weird lock-right-after-login behavior is related to the fact that I get logged out as described above. It seems that the shell remembers that it is supposed to be locked despite the crash / logout, such that when I log back in, it realizes that it's supposed to be locked and locks itself. Note that I am filing this bug as instructed in https://bugs.launchpad.net/gnome-shell/+bug/1721428/comments/105: "BTW, we have fixed many gnome-shell bugs with these symptoms recently in Ubuntu 18.04. So please try 18.04 and log a new bug if you have any problems."
