Hi
I need some help debugging my failing x2go sessions please.
Client is v4.0.2.1 on OSX Mavericks. Server is 4.0.1.18 on Fedora 20. This is one of Orion's builds for Fedora.
I've been using server version 4.0.1.15 for some time, but its a bit flakey in the sense that often it is not easy to reconnect to a session, ie it takes several attempts or the session must be killed and started a fresh.
I was trying to see whether the 4.0.1.18 server would fix this issue but it seems to have bigger problems for me.
What works is:
Connecting to another Fedora 20 system running v4.0.1.15 server on with a KDE session but with the problem of not being able to resume sessions reliably.
Connecting to the 4.0.1.18 x2goserver with a single terminal session.
What fails is: Connecting to the 4.0.1.18 x2goserver with a KDE session.
I get no session at all, and in the client window I get a message simliar to "your connection was closed before it got into a usable state". The connection dialogue disappears before I can read it all, and I can't see where it is saved.
In /tmp/.x2go-rmj/C-rmj-159-1414083481_stDKDE_dp32: the state file says STARTING the cmdoutput file says: exec startkde
Output of session.log is appended at the bottom.
There is more debug info available from /var/log/messages from having set loglevel debug in /etc/x2go/x2goserver.conf which I'm happy to share off line.
I've tried setting full debugging in kdebugdialog but nothing at all was logged to ~/.xsession-errors.
I'd appreciate any pointers to how to debug this further. I can, of course, log in a KDE session on the console of the system running the 4.0.1.18 server and a simple x2go session running only the Terminal appliation works too on that server.
Thanks
Roderick
