Bug Description

I have my laptop sitting in half-clamshell on the desk hooked up to external monitor via HDMI.
By default my monitor config is to have the screen displayed only on the monitor on my desk and not the laptop.

This work fine as soon as I log in, however at the login stage it has defaulted to displaying the screens in extended mode, with primary display on my laptop, which means I have to move the PC, open it up and login there before the displays go back to the setting I have chosen.

Generally not an issue except its a nuisance to have to move them around every time I login.

Wondering if this is a big or if its intended behaviour ?
