Well, we do have several HPC cluster operators that use X2Go - see our "success stories" list in the Wiki. Maybe it would make sense to contact them directly and see if they've had the same issue? Also, why can't you run X2GoServer directly on the execution nodes, instead of using ssh -X? If the login node is the only one with a publicly accessible IP, that's not a problem - Activate the proxy feature in the X2GoClient session setup and tell X2GoClient to use your login node as an SSH proxy (i.e. "jump host").
