[FreeNX-kNX] freenx + RHEL4 = black screen

Hello,

I have a black screen after login in NX, no splash, no KDE.

I can open an xterm, and startkde with this method in the server:
$ su - user
$ DISPLAY=:1000 xterm

But I can't open KDE directly in the client (windows or Linux, version
3.2 or 1.5).

If I open an application directly with the custom configuration of the
client session, the window are closed automatically after login. But in
the server, with nxserver --list, I see a running session.

What the HELL ??
I don't understand...
