mdmlogin multi monitor support lacking about mdm HOT 5 CLOSED

Imho there should be first some discussion as to what most popular multimonitor config might be
My personal choice - mirrored screens on both builtin and external monitor, with redetecting from time to time attached monitors or doing that after poweron/hybernate/suspend/lid open/close events), for same login prompt to be displayed everywhere (drawback - it might look worse, if display device has higher resolution, then lesser one from both), with user desktop configuration (possibly different) applied only after login.
Similar alternate configuration - also mirror screens just on lesser/worst one use xrandr scaling >1, so that biggest resolution gets used, scaled up (and worse picture quality) - on lesser one.
Also there could be some reasonable common small resolution with mirrored displays set, +button in mdm screen of drop down list with selectable some other common resolutions and remembering choice (+keyboard combo to reset to defaults of smaller resolution in case if user errors with choosing undisplayable one).
Also there might be some Display Settings integration that would generate 'mdm-only' monitors.xml, or shell script that runs xrandr to set custom configurations.

Well, that's tricky... because typically mdm isn't part of your user session, so it can only obey system configuration. Whatever is in ~ relates to one particular user, not the entire system.

I take your point though, we need to be able to tell MDM which monitor to use. Maybe that can be added in mdmsetup.

You could also display the login box on the screen with the mouse cursor
(and move it when the mouse moves).

Yes, but the mouse cursor could start in the other monitor as well.. that's not ideal either.

Fixed in git.

greeter/PrimaryMonitor added to settings and to mdmsetup.
