I'm a new user and trying to share a session on different machines/displays.

So, on the server I start a session, say DISPLAY=:50 from a client with a regular 1960x1280 screen. When I move to another machine/display, for instance using a 4K screen, I can share the desktop. I'm getting a 1960x1280 desktop with the windows on :50.

That's not really what I want.

Instead, I would like to get all :50 windows -without- having a special window for the desktop. Ideally I would like to move the windows :50 independently of the original session. Since, on the 4K screen, I prefer a different placement of windows. Ideally I would like to share a group of windows belonging to one part of the process-tree. Essentially this means that window positions should become client specific.

Is something like this possible at all?

Please note I'm not subscribed on this mailing list, I will watch the mail-archive now and then.

P.S. desktop sharing leaves echoes of a moved window in the desktop, this is a bug I guess
