This issue affects me as well. Lenovo T460 and a Lenovo basic docking station. The docking station is connected to an Acer 24" monitor via VGA. Once the desktop locks and the unity login appears the external display enters power save mode. Unlocking via the password does not power up the external display (all windows are moved to laptop display). I have to eject the laptop from the dock, wait a couple of seconds, then put the laptop back in the dock for the external display to power back up. I'd prefer not to physically undock/dock the laptop several times a day.
