[FreeNX-kNX] Black Screen after Establishing the NX-Session - FreeNX V.0.7.1

Hi,

I installed the latest version of  FreeNX v. 0.7.1 on Debian Etch system 
using wiki from this link below

http://wiki.slashconcept.com/index.php/FreeNX_Remote_Administration_unter_Debian_GNU_Linux_4.0_Etch_Howto

I use the  windows NXClient v 3.1.0.3 from NOMACHINE to connect to the 
freeNX server using the option Desktop->Unix->Gnome. It works fine !!!

Now  I try to connect to a linux machine which runs X-server too, via 
freeNX server. Therefore I need to set the NXClient as below :

*Desktop->Unix->XDM ->Settings->Login->Query an X desktop manager->host 
192.168.1.227, port 177*

Scenario:
*Windows NXClient -> freeNX server 0.7.1 -> linux server (x-server)*


!!! But I get a black screen. ???

There are no any error messages in the log file

The session is established if I check this

The test using NXSERVER version 2.1.0-22 -LTE  from Debian  runs fine, 
which was installed with apt-get. I can connect to 192.168.1.227.

What did I do wrong here ?
Do I forget something ?

Please help !!!
