Public bug reported: I'm using a laptop with no external monitors attached (System76 Oryx Pro 2016).
After the screen is locked (either manually or via timeout) and it blanks/deactivates the screen, the display remains deactivated and my session is unrecoverable. (I can still ssh into the machine, but have so far been unable to get the display back without rebooting, even via restarting gdm.) It seems somewhat similar to https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1715811 , but it's only after the display is deactivated, and not at boot. The scope of the problem seems to be compounded by the fact that there's no straightforward way to prevent gnome-shell from blanking the screen when it locks.
