I'm using multiple monitors. When logged in everything I fine. Left monitor is positioned left and right monitor is positioned right, but before I login the login screen positions them the other way around.

This is also the position as used bij bios/grub, and I don't mind where the login is displayed, but when moving the mouse the boundary is the wrong way round, and that's annoying.

I was experiencing this too. So long as you have your monitors configured as you want them in your user space then you should be able to follow these steps to set your monitors up the same way on the log in screen:

  • Open a terminal
  • Type sudo cp ~/.config/monitors.xml /var/lib/lightdm/.config/
  • Enter user password
  • Reboot your computer

Kudos goes to this post over here for pointing me in the right direction: Wrong Login Screen Resolution

Thanks, solved the problem! – TD_Nijboer Oct 26 '13 at 20:07
Just wanted to say that this also worked for getting the monitor rotation set up correctly for the login screen. Thanks for the solution. +1 – reirab Mar 12 '14 at 19:06
Thanks for pointing me in right direction but the same thing can be done with just one command from users home folder: sudo cp .config/monitors.xml /var/lib/lightdm/.config/ – Tanel Mae Mar 14 '14 at 17:26
This truly helpful solution!!! – Dmitry May 19 '15 at 7:33
On 14.04 this changes the login screen to be the same as one user, but doesn't set the default for all users. – mirams Jun 23 '15 at 9:24
