So I've configured my desktop so that Monitor 1 is on the left, while Monitor 2 is on the right.

But after a reboot, the monitors switched position, so Monitor 1 is on the right, while Monitor 2 is on the left. (They reverted to my desktop configuration after login).

I have read this question, but that's for LightDM. There is no /var/lib/lightdm in 17.10

So, how do I change the login screen monitor configuration?

If your monitors.xml file is set up the way you want your monitors to be after you log in, try this and reboot. Note that by default there is no existing monitors.xml file under /var/lib/gdm3/.config (at least it wasn't there for my setup.)

sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config

i fixed this by uncommenting the #WaylandEnable=false setting under [daemon] and saving at the /etc/gdm3/custom.conf location on my triple monitor setup. found the resolution here: https://ubuntuforums.org/showthread.php?t=2397584&p=13788383#post13788383
