gdm instead of kdm

Hello people,

I installed opensuse 12.1 with a KDE desktop but later I decided to go back to Gnome. Allright but the fact that the login keeps being proposed by kdm rather than by gdm.

How do I configure such a thing ?

Thanks

Yast > System > /etc/sysconfig editor.
Then +Desktop +Displaymanager DISPLAYMANAGER.

Thank you !

A quick note: changed also the default window manager to gnome from kde4

Bye
