Hi,
I'm a new user. I'm under Ubuntu 12.04 with gnome-shell and I have installed x2goclient. With the update I have now 'X2Go Client v. 4.0.5.0 (Qt - 4.8.1)' One another computer I have installed x2goserver and x2goDesktopSharing
Is-it possible to launch x2goDesktopSharing as a service when launching the system (same as x2goserver), to be able to disconnect of the user and reconnect to another.
For now, disconnecting (:0) kills the nx connexion.
I have other troubles, but I will open a new thread.
Thanks A+

That sounds like you want to run X2GoClient in ThinClient mode, instead of your usual login manager, and run X2GoServer on the same machine.
Not exactly a beginner's task, but I don't see why it shouldn't work.
By starting an X2Go session on the same machine, you're making it detachable/suspendable, so that would be what you're looking for, I gues s.
An easier, yet clumsier way would be to log in as usual, but instead of starting regular applications in that screen, fire up X2GoClient, connect to localhost with a fullscreen session, and work with that. Same effect - you now have a session that you can detach/suspend and reattach from somewhere else.

I want to be able to disconnect on the server but not the x2go local connexion, and to receive the machine's connection screen. For example, on a machine (server), I have two users 'alain' and 'beatrice' If I connect with x2go to alain, I want to be able to disconnect from alain, without closing the x2go connection, receive the connection screen, and reconnect to beatrice.
Am-I clear, and is-it possible ?
Thanks A+

No, that will not be possible. X2Go uses the credentials you supply to open an SSH connection to the server, so, once you log out, the SSH connection closes and the server has no idea who you are.
We rely on SSH here, and that protocol simply has no means of swapping credentials mid-session.
Maybe you could explain *why* you feel you have the need to do that, so we can try to suggest alternatives?

The man says its possible, when launching with the option ---activate-desktop-sharing, it seems to work, but it seems that enabling or not the desktop sharing, I'm able to connect to the server. Is there a difference ?

Desktop Sharing allows you to take over a local session (:0), or an already running X2Go Session (usually :50 and upwards).
It will *not* allow logging in when there is no active session already present on the :n Display that you try to connect to.
For example, even if you have a login manager like gdm or kdm running on :0, X2GoClient will not be able to "grab" that screen and share it using Desktop Sharing, as there is no user logged in at that very moment. Only *after* logging in, the user's session can be captured and shared using DS - and once the user logs out, the DS session terminates. That's exactly the effect you've mentioned in your first e-mail to the list, and this is intentional.

But it was not exactly the question I asked for.
What is the difference between connecting with x2go having or not activated the desktop sharing ?

The difference is that with desktop sharing enabled, you can attach to an already running session, for example, to remotely guide/assist the user that is running the session (either locally on :0, or on an X2Go screen), while without desktop sharing, you can only attach to a suspended session. In other words, without DS, you are "stealing" the display from the other machine, it will disconnect there once you resume it from the new location. Also, you must use the same user credentials to do that, while DS allows another user (admin/support staff) to see what the original user does (as well as control mouse and keyboard for the other user).

How to be able to manage the list of allowed users ? I saw that on the x2go newsgroup which was posted on 2012-11-23
Adding users to x2godesktopsharing happens once another user connects to your account. The GUI, of course, can be improved here: adding users before they connect via the GUI could be a possible feature request.
