Keyboard shortcuts when locked?

Is there a way to enable keyboard shortcuts when gnome is locked? I use a shortcut to switch between two monitors with gdctl and sometimes my main monitor is sleeping when the other is selected. Since the monitors are very far apart and at different angles, I can’t see if I’m typing my password from my desk.

I may be hallucinating, but I swear this used to work, I could hit my shortcut at login to enable my display, but recently this stopped working (or it never did in the first place).

Anyway, is there a solution or workaround for this?
