That sounds like a second bug which I was trying to keep separate. Sounds like a partial success now at least, since the monitor is /more/ black if you leave the peripherals unplugged. Because it would fully wake if you left the peripherals plugged in. Unless I have missed something.
Back on that secondary bug, does the backlight go off in the original case with the peripherals plugged in? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1852101 Title: Monitors keep turning on when in power saving mode, every time.
