I use libreoffice on my X11-server and then I want to continue to work on the same text in the same window from another place using VNC.So, it would be nice if it is possible to detach a X11-window from one Window Manager and attach it to a different one (on a different DISPLAY running on a different X-server) which is already running.I'm using the awesome window-manager.Is this possible?
How to move a window from one Window Manager to another running WM?
x11;window manager;window
There is screen to do that with (virtual) terminal applications, and there is xpra for X11.
