gnome metacity & Terminal Server problem

I set up my openSUSE 11.4 64bit as Terminal Server.
I have HP thin clients boot from lan (pxe) and connect to gdm (xdmcp - enable).
When i login from thin client there is no titles of the windows and i cant resize and move windows.

I think that it is metacity problem? but i cant understand how to fix it :frowning:
