Current version is 3.5.99.26. Please retry with that version. See https://github.com/ArcticaProject/nx-libs#binary-builds where to find it if it does not come with your distribution.

Java applications have always been special so it might be necessary to switch to xrender or fake the window manager. Please check this mailing list for a posting of mine from around 2-3 weeks ago where I listed the possibilities.

NXAGENT - Version 3.5.99.19

 

It’s giving me a error 51 (The connection with the server was shut down) on the client end. When I look on the server after getting kicked out with an error 51, there is no session running.

Well, I do see any java related hint in the log. Is the session really crashing or just disconnecting?

 

What's your version of nxagent on the server?

We are having problems with X2Go crashing whenever a java application launches. The behavior we’ve seen this with are Matlab and Libre Office. The error log for a session is below:
