[X2Go-User] x2go local desktop connection on rpi

[RW]

Hi,

I've recently been trying to use X2go to connect to a Rpi3 running the
latest ubuntu mate 17.10
This seems to work when selecting xfce or a new session
but doesn't work when trying to connect to the local desktop (which is
already logged in)
I even tried installing / running x2godesktopsharing on the server side
then enabling shared desktop, but that didn't have any affect (I think
that's only needed for different users normally)

  * client - Windows 10 / latest X2go client 4.1.0.0
  * server - Rpi3 / Ubuntu Mate / latest x2goserver
4.0.1.22-0~1197~ubuntu17.10.1

It just seems to jump out with the following message on the client
"The connection with the remote server was shut down. Please check the
state of your network connection"

  * I was able to rule out the client as the problem by connecting from
windows to a x64 gentoo vm / local desktop vm which worked fine on the
local desktop setting (same version 4.0.1.22 server)
  * I also tried connecting from a linux client to the rpi but with same
results
  * For the rpi as the server, this only seems to affect connections to the
local desktop, connections using a new session in the drop down work okay

Logs attached below
any ideas on how to get this going?
one difference I've spotted with a working setup is the message "state file
for this session does not exist" in the server logs
