Hello,

I am experiencing the following problem, of which I am not quite sure which package causes it:

I am trying to connect with an x2go client running on a Windows 10 system to a remote x2go server which I set up on a Debian Jessie 8.6 virtual machine (Kernel version 3.16.36-1), using XFCE as graphical interface. I am able to connect and establish a session, but if I suspend the session and try to resume it, the client closes the connection, and nothing works until I restart the server on the remote system. If I terminate the session and then try to open a new one, everything works fine.

X2Go version on server side (installed via apt from http://packages.x2go.org/debian):

x2goagent: 3.5.0.32
x2golxdebindings: 1.0.2.4
x2goserver: 4.0.1.20
x2goserver-extensions: 4.0.1.20
x2goserver-xsession: 4.0.1.20

X2Go client version:

x2goclient: 4.1.00

Content of the session.log when opening a new session, suspending it and trying to resume it:

I have tried also the following:

- Accessing the remote machine from a different system (Ubuntu 16 with X2GoClient 4.1.01), with the same result

- Using an external x server on the client side, with the same result


So far,  my guess is that this is some sort of authorization issue on the server side; the x2go installation on the remote machine was done using a fakeroot environment, although I have no idea how this could influence the resuming.

I would be very thankful for any kind of advice!

Best regards,

Martin
