Support I have two computers. Each computer has a X server running. And one of the computers also have some GUI applications running on it.
Now I want to keep the GUI applications still running on the same computer, and they’re still getting keyboard and mouse input from the same computer, while redirect their display content to the X server on the other computer. The role of the displaying X server is simply rendering, so device sharing solutions like Synergy is not satisfied in this case. It may sound strange, but is essential for security issues.
I’d like to know whether it is possible to make X server work like this. If there is no existing solution, will it takes much effort to modify X server source code?
Sounds like you want either Synergy: http://synergy2.sourceforge.net/ or x11vnc: http://www.karlrunge.com/x11vnc/
