Hello again Mihai.

I recorded a screen capture while trying to start a connection from another computer. See the link below.
As you can see, it seems the connection gets opened but the window crashes immediately. I have tried from several computers (including one with Windows) so I don't think it's a problem on the client side.

I have attached an extract of the /var/log/syslog file these last minutes. I see nothing that looks like an error to me. Obviously, you should be able to interpret it better than me.
I have also restarted x2go (sudo systemctl stop x2goserver.service and then sudo systemctl start x2goserver.service ) after changing the /etc/x2go/x2goserver.conf file with logging to debug. That is the second text file attached.

In it, I can see :
Mar 15 14:51:15 ServeurITeN /usr/bin/x2gostartagent: successfully started X2Go Agent session with ID manfred-50-1521121872_stDXFCE_dp24
Which means, I guess, the session was properly started.
However, further on, I can also see :
Mar 15 14:51:22 ServeurITeN x2gogetstatus: db_getstatus called, session ID: manfred-50-1521121872_stDXFCE_dp24, return value:
Mar 15 14:51:22 ServeurITeN x2gocleansessions: manfred-50-1521121872_stDXFCE_dp24: removed from database, not updating status.
Mar 15 14:51:22 ServeurITeN x2gocleansessions: manfred-50-1521121872_stDXFCE_dp24: in failed state, but agent is gone, forgetting.
Is that some kind of failure ?


It is also interesting to see that when I issue a who command with the Linux Terminal , there is one extra session under my login.

So I tried opening a x2go session with another login, which also failed but with a different error message : "Failed to start X2Go Agent session with ID formation-50-1521122343_stDXFCE_dp24. X2Go Agent terminated unexpectedly. Aborting session startup." I then restarted the x2goserver.service again and tried again with the other user account and got the same error as for the first user ("The connection with the remote server was shut down. Please check the state of your network connection.").

Any idea ?

Okay, up to date and no partially installed packages or version mismatched for
that matter.

That still leaves the "crash on connect" bug if the window was started a window
different from the first one in a multi-head setup.

Nope, it's just the cleanup process that loops through all session data and
syncs up or terminates stale session as necessary.

It's spammy (hence why I said "a lot of data"), but perfectly normal.

You'll have to make an actual connection attempt to see more interesting stuff.
