Re: [X2Go-User] GNOME and Unity can not launch

  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.
