Cannot rotate primary display when external monitor is connected
On 2-in-1 style laptop, screen auto-rotation works nicely when not connected to external display. However, when external display is connected, the primary laptop display reverts to default orientation. In addition, there is no option in Display Settings for changing the orientation of the primary display manually. Use case: would like to leave the laptop folded in tablet mode with screen rotated 180 degrees, while using external monitor.
