The path was wrong in #6 (I forgot the /.config/

Copying

/home/<user>/.config/monitors.xml

to

/var/lib/lightdm/.config/monitors.xml

fixes this issue for me (see image attached).

Btw.: After upgrade to new HWE/Xorg I had to resize my monitors to get rid of similar situations for the gnome session itself. That could be done by reajusting resolution two times (go for wrong resolution and back to right resolution). But that could be done via GUI (system settings/displax devices). Be that a bug in itself or not, I think it is not convenient, at least.

However, the GUI setting did not affect lightdm monitor settings. Only copying monitors.xml to /var/lib/lightdm/.config/ did.

For lightdm, I think this is a bug, just because it requires non-GUI user interaction. Average users should not be tricked into such situations.
