Greetings:  We are new to the list  -- hoping to get some help getting things to work on Ubuntu 10.04 Lucid

we have installed the server (per instructions) and a windows 32 client. 

When attempt a login session we get the following error:

“Can’t read host RSA key C:\cygwin\etc\ssh_host_rsa_key.pub”

The session information displayed in the client window is as follows:

I have a version of FreeNX loaded on the Windows box.  The FreeNX client is version 3.4.0-10.

When installing the x2go client on the Windows box we retained the existing CYGWIN installation.  This installation is rather old – perhaps it is not consistent with the expectations of the x2go app(?)

The session does in fact load – but the response times are very slow --  The app initially reports “Not Responding” but sometimes it will generate meaningful menus / responses.

Can someone help us figure this out?
