[sf-lug] Display login Screen On External Monitor

My MSI GP66 laptop screen died awhile back, but since I use an external
monitor, it was more of a nuisance. Can't see the firmware settings, grub
screen, or login screen, but for login, I have been able to blindly type in
the proper keys.
The instructions for getting the login to the external screen are pretty
straightforward (set up a single screen, then copy your
.config/monitors.xml file to ~gdm/.config (provided you use gdm), and that
worked on another laptop, but not the MSI.  Turns out, that simply creating
the /etc/X11/xorg.conf  file was all that was needed (easy from the
nvidia-settings).  No edits were necessary, just the presence of the pretty
basic config file with the defaults it was already using when no file is
present.

I suppose the grub screen is the next project.  I did get the instructions,
but they didn't work for me, so maybe just some tweak like the login screen
is needed.
