OK so the X stuff is working . . .

As your shell ??

You could be 100% of the user base on centos6 ;)



OK, so the desktop isn't starting corectly (or fully).

Did you check how far it gets - do you have a launch script starting up ??


Is it still "startkde" and "gnome-session" in Centos6

i.e. (the defaults are actualy set by nxloadconfig)

#COMMAND_START_KDE=startkde
# The key that contains the name of the script that starts a gnome 
session.
# It's run when a 'unix-gnome' session is requested by the client.
#COMMAND_START_GNOME=gnome-session


or what do you have configured in /etc/nxserver/node.conf

Which one are you using anyway ???

Is it working ok without NX



If so . . . .


Try it with xterm instead of start kde or gnome or whatever you are using.


i.e. in the nxclient

        <Gereral>(Tab)<Desktop>(section)
configure
         Unix  &  Custom ( menus )

in
        <Settings>(button)

Check
        <Run the follwing command>(checkbox)

enter xterm in the text box.


You can try with both

        "New virtual desktop"
and
        "Floating window"

in section "Options" just below.


You should see a nice quick xterm window appear on your desktop.


Try starting your desktop managerwithin that first 
and see what happens
 (note it's better to have "New virtual desktop" for that one !!
         so you have a root wiindow)

Let us know how you get on . . . .
