You have been subscribed to a public bug: Xubuntu 18.10 with Xubuntu.desktop session running. System will lock and turn-off monitors(automatically or manually), but--will not wake-up monitors upon keyboard or mouse activity. I can type unlock password, blindly and then the monitors will wake and show unlocked session.
WORKAROUND: I uninstalled light-locker, then, I installed gnome- screensaver. Xfce4(Xubuntu.desktop) will fallback on gnome-screensaver if light-locker is not found or installed.
