[FreeNX-kNX] x11 client initiated but not displaying

[Neil Levine]

Hi

I am running FreeNX on a Debian unstable box:

freenx  0.4.4+0.4.5-3
nxagent 1.4.92+1.5.0-4
nxlibs  1.4.92+1.5.0-4 

with the NoMachine nxclient (1.5.0-135-1).

I authenticate to the remote server fine and I can see nx initialising
on the server with the remote client appearing in the process list
(xterm in this instance). 

However, nothing gets returned to the client display. Xterm sits in a
select() until 30 seconds later the session times out ("No response
received from the remote server.")

I have seen the similar sypmtoms described here:

http://openfacts.berlios.de/index-en.phtml?title=FreeNX_FAQ/Problem_Solving

but nothing works/is relevant.

This exact setup, with these exact versions _did_ work prior to an
apt-get upgrade a week or so ago, so it is presumably something X server
related, however, despite setting NX_LOG_LEVEL=7 no useful information
is getting logged:

NX> 706 Agent cookie: c23daaf3ff610a7d87af2cab004eda41
NX> 704 Session cache: unix-application
NX> 707 SSL tunneling: 1
NX> 710 Session status: running
NX> 1002 Commit
NX> 1006 Session status: running
NX> 105 bye
Bye
NX> 999 Bye
NX> 1009 Session status: terminating
NX> 1006 Session status: closed
NX> 1001 Bye.

.xsession-errors does not show any errors relating to the client either.

Anywhere else I can look for potential clues?
