I just said yes that it stays dark, and plugging them in did not seem to "wake" it back up. The system does not appear to be properly entering ACPI sleep, just that the screen is "black" (but I can still see the back light through the LCD matrices).

Status in gnome-shell package in Ubuntu: Incomplete Bug description: Whenever I lock my computer, or it goes into power saving mode automatically, the monitors turn back on and show the lock screen a few seconds later. This has persisted now for about a year, has persisted across multiple upgrades (18.10, 19.04, 19.10) as well as complete hardware replacement (CPU intel -> AMD, GPU nVidia -> AMD). So I'm convinced this is a software bug. The first line in logging that I can find that seems to trigger this is: "gnome-shell[1967]: ../../../gobject/gsignal.c:2647: instance '0x55daa50a2920' has no handler with id '145952'" I update my system regularly, so this looks to either be a regression, or uncaught bug. I don't know if other things are causing this, but that's the first line (based on time) that is reported when it turns the monitors back on.
