OK , that's not all of it though. There should be a startkde and a 
start_kdeinit or some such somewhere . . . 

But sounds like the difficult bits are working though.

Looks like it isn't finishing off either starting up or shutting down ( or 
both ) properly

It might be worth trying a different user if you haven't already . . .

Also

If you set debug on in /etc/nxserver/node.conf *ON THE SERVER*

NX_LOG_LEVEL=6
NX_LOG_SECURE=1
# writeable for the "nx" user
NX_LOGFILE=/var/log/nxserver.log
SESSION_LOG_CLEAN=0


You should see in the log where it is getting stuck.

Are you setting up printers or shares, if so does it work without them.



You will need to set up debugging, then make a fresh connection, 
disconnect and connect again !!

I get the following. The  NX> 999 Bye is where the startup finishes, the 
last line when I terminate and disconnect.

NX> 105 bye
Bye
NX> 999 Bye
session_status A ... B Terminating
server_nxnode_echo: NX> 1009 Session status: terminating
session_close A ... B
server_nxnode_echo: NX> 1006 Session status: closed






If you have the Nomachine client on the server, you can run

nxclient --admin

as the user, which will tell you what it thinks is still running looking 
at the .nx directory.
