GDM not displaying KDE

[Arden Wiebe]

When I log out and back in I don't see an option for kde.  It only shows gnome.  What else must I install to test KDE4 on fc9?  I need access to smb via smb4k.  Also the graphical gnorpm tool isn't working:  Yum cache was invalid and has been rebuilt is all that it says.
