First I have no idea why it crashed even that I<br class="">saw icewm (Window Manager you are using) errors in the log. Proper<br class="">trouble shooting will involve some serious DTrace-ing which is not<br class="">available on Linux.

NoMachines the Italian company behind NX<br class="">protocol went fully proprietary few years ago and I suspect that libnx<br class="">libraries are no longer properly maintained. We could try to purchase<br class="">proprietary server license for NoMachines NX and see if it going to work<br class="">better. I am also concern that X2Go clients don't work properly on<br class="">certain platforms (primarily OS X). I use quite regularly X2Go from my<br class="">DragonFly BSD machine at home to connect to the lab and use MATLAB.

However VNC is notoriously insecure and would<br class="">require lots of open ports to work. It is also supper buggy.
