Remote X login in SUSE9.0?

Hello SUSE folkz, In the previous versions of SUSE I could enable remote X login to the system using YAST. "X -query host_name :2" worked all the time. Now in SUSE 9.0, when I try to X login from another box, all I can see just a blank X server window without graphical KDM login interface. I suspect I should enable remote X login for KDM separately from the X server, but I don't know where it is. Could somebody please help me with this issue. Many thanks in advance. Alex
