The xauthority files are different.

If you don't have a valid X authority between your NX session
and
the running current :0 console session
then
you will just see the window close, which is what you reported.


 But Its not the main problem i think.
I used xauth add to add the authorization to ~/.Xauthority and run again

Are they both using ~/Xauthority tho ??


I foundsome more info which could point to the problem.
The nxagent has a segmentation fault a little after it tries to .
I found the coredump in the system
