I'm just starting to use x2go, and it has mostly worked great.   But, I have run into problems where I connect to my server, get authenticated, but never get my application displayed.    I can see the x2goagent process running on the server, but the app never displays.   Creating a new user account and logging in with that has usually succeeded as a workaround.   But, obviously that's not a solution.

I'm sure there is a simple fix for this, like cleaning up some lost session data.  But, my attempts thus far have failed.    Are there any session debugging tips available?  Or, pointers for where to look or how to enable more debugging output?
