KDM login & dual monitor setup -- greeter on wrong monitor


A while ago I was running gnome + gdm and the greeter had the nice trait that the login window would follow the mouse pointer. So if my mouse was on the left side, the login would show up on the left monitor, if it was on the right side… you understand.

Currently I use openSUSE 11.1 with the standard KDE4.1.3 packages. Unfortunately KDM always shows up on the 2nd monitor (left side) and not on my primary (right side). The 2nd monitor is connected via VGA, the primary via DVI.

Where would I change that behaviour ?
