Anybody know of a way to do this? Let's say I have a multiheaded setup with one X server and two displays, :0.0 and :0.1 (no Xinerama). Is there any way to have one instance of an X client (e.g. xclock) and cause it to be displayed on both displays at the same time? Maybe easier if it's two separate X server processes (i.e. :0 and :1)?
I have read about some ways of doing this with VNC, but I don't want the extra overhead of running a VNC server and a VNC client. I really want to be able to just tell the X server "make two copies of this client's window, put one on display :0.0 and another on :0.1"
