MDM login screen and multiple monitors

[devosion]

When I boot up up with my dual monitor setup my login screen always appears in my second monitor, and not the primary monitor that I setup with the nvidia control panel, which always appears black. When I was using ubuntu lightdm had a nifty solution by activating both monitors and determining the orientation of the login screen by the location of the mouse. Is there a way I can set up something similar with the mdm login, or a way to have it only appear on a specific monitor? If so how do I go about doing that?

I am having the same issue, only I have a laptop and two monitors. I usually have the laptop docked and unopened since it only supports two monitors at a time. When it boots, it uses my primary monitor for grub and the iniitial splash screen, but then insists on using the (closed) laptop monitor to display the login screen. I then have to open the lid to see the login form. Once I login though, it switches back to the external monitors. I would like a way to force it to use the external monitors is the lid is closed. Is there a setting for this?
