From the x2go log I see this: XSession-x2go: X session started for xxx at Thu Aug 10 09:06:10 EDT 2017 xrdb: Connection reset by peer xrdb: Can't open display ':86'

The XFCE logs have this: TRACE[xfsm-manager.c:1295] xfsm_manager_save_yourself_done(): enteringTRACE[ice-layer.c:99] ice_error_handler(): ICE connection fd = 19, ICE I/O error on connection TRACE[xfsm-manager.c:428] xfsm_manager_handle_failed_properties(): Client Id 28106ab6c-8ea1-4c3e-b5f3-91794321ccb5 exited, removing from session.

So could something in the user's .bashrc which I'll paste here be causing this?
