Not sure i know what I`m doing.
I need to establish a connection to my centOs server that allows X11 forwarding.
It seems the connection succeeds - but i get only a grey screen and once in a while the connection is broken. Please see the screen shot of the message attached.
Here`s the connection log:

Why does the connection fail ?


Program Ver. : Xmanager 4
Connect Method : Secure XDMCP

A bug in GDM in does not allow secure XDMCP on most machines. To use Secure XDMCP, please follow the instruction in the following link:

Xmanager Faq : When I use GDM, I cannot make a Secure XDMCP connection.
