With Xming I can run an X11 server inside a window and then run mate-session to get a very fast remote desktop inside a window. On Linux, I'm not entirely sure how to X11 forward mate-session to just one window.I know how to replace my entire desktop with the tunneled desktop. I know how to do it to a TTY, I know how to do it for individual programs and I know how to do it inside a virtual machine.It just seems strange that I wouldn't be able to do it in a minimize-able window, like you would with a remmina VNC connection.Is there a program that provides an x11 xserver inside a window? or is there a good way to do that with a chroot? or something else similarly efficient.I'm running Fedora 23.
Xming for Linux? (Aka run a display/x11 server inside a window)
ssh;fedora;gnome3;chroot;xming
One of the questions you ask is: Is there a program that provides an x11 xserver inside a window?It sounds like Xnest might answer that question.  Xnest is A nested X server that runs as an X application.  I know that I've used it in the past to show me unusual window managers that I had compiled from source, and didn't want to have crash my whole system.  I'm not sure it's the answer to your problem, however.
