I think there is issues in handling such case in gnome-shell/bionic itself. With an Intel card only platform, one may login via gdm displayed on the external monitor. But when logged in, the built-in display will have the content of a second one, and the external monitor will be blank. Then if you unplug HDMI and replug in, the external monitor will have the content of a second one, but the built-in display will be off.

So there might be an hardware/nvidia/i915 issue in `edp_panel_vdd_on()`, but upgrade the system to Disco/Eoan is still a must to receive new fixes for related behaviors.
