First of all, you shouldn't set LD_LIBRARY_PATH at all. The new X2Go Server versions don't do it and you shouldn't either. /usr/lib/x86_64-linux-gnu in there should even be fully redundant and messes with the default linking order. Not just that, but it means that our DT_RUNTIME trick in nxagent, which is supposed to override libX11 linking against a compatibility symlink (libX11 -> libNX11) installed in a specific directory, is not working - hence loading the wrong libX11 library and thus leading to nxagent failing to open its internal display.
hi Mihai
thank you so much! the /usr/lib/x86_64-linux-gnu in the LD_LIBRARY_PATH was indeed the culprit! after removing it, I am now able to log in all my servers!
I checked my file modification history for .bashrc, I added this path for a subset of my machines on March 11. It was also the window when I applied the package updates throughout my cluster, so I mistook the issue to the new packages. my bad!
once again, thank you for the insightful suggestions, and I am so happy x2go works again!

Be careful when you mess with stuff with that.
