gdm login default setting is where?

[David Tonhofer, m-plify S.A.]

Hi,

And now for a silly question:

When logging in through gdm in RH ES 4, I can choose one
of the GNOME/Default/KDE/Failsafe sessions. Where DO I set
KDE as the default (the menu always starts with GNOME
pre-selected)? Tudjeu!

Best,
