Unfortunately with Unity you have the same issue. Canonical has dropped

Unity-2d support so that's a problem with X2go (and NX) as well.

Thank you for the reply. gnome-shell --version reports 3.10.4 and gnome-session --version returns 3.9.90 with no composite extension in the server. I am not an administrator of the remote server, so it seems that I have to give up gnome. What about Unity then? It's the default GUI for ubuntu.

PS: Mate desktop works but I don't know how to play with it.

 If the server is a modern Linux with Gnome 3 this will happen because

Gnome 3 uses a compositing desktop not compatible with X2Go.

 For me the fix was to install Mate desktop on the servers which is a

fork of Gnome 2 and is compatible with X2Go.

Hi,

I installed the latest X2Go client, but it only works with KDE. When I tried to launch Unity and GNOME desktop, they always fail. To be specific, when I selected Unity, the desktop just flashes and disappear. When I selected GNOME, I got a black desktop window and VcXsrv reports an error saying "Cannot establish any listening socket - make sure an X server isn't already running". The contents of VCXSrv.0.log is:

_XSERVTransSocketCreateListener: failed to bind listener _XSERVTransSocketINETCreateListener: ...SocketCreateListener() failed _XSERVTransMakeAllCOTSServerListeners: failed to create listener for inet6 _XSERVTransSocketCreateListener: failed to bind listener _XSERVTransSocketINETCreateListener: ...SocketCreateListener() failed _XSERVTransMakeAllCOTSServerListeners: failed to create listener for inet (EE) Fatal server error: (EE) Cannot establish any listening sockets - Make sure an X server isn't already running(EE) (EE) Server terminated with error (1). Closing log file.

I have no idea how to check if any X server is running on my computer. All the settings of X2Go are default. The remote machine is ubuntu 14.04. Any help? Thanks.

  Compositing desktops are not supported by either NX or X2Go at this point

to the best of my knowledge, so the answer would be no.

Thank you. So, if I may ask here, is there any other remote desktop software that supports composition (and easy to use)?

just a side note for Robert (who is one of the X2Go power users). I have been experimenting with the Xcomposite extension in NX and in our process of updating and cleaning up stuff, I think there is hope that we will find a way of enabling the Xcomposite code in NX in the near/far future. For GNOMEv3 also the GL extension needs to be updated, which will be a more complex endeavour, though.
