I am running X on two displays. :0 is my primary display but I also have some programs running on :1. Is there any GUI application that will let me monitor display :1 in a window that sits on display :0?

(Using gnome, FWIW)

Monitor in what way? See it, or something else? – slm Nov 24 '13 at 3:19
Yes, I want to see display :1 in a window that sits on display :0 – f.ardelian Nov 24 '13 at 3:36

I know of 2 ways to do this when the system is remote, so given the 2nd X server is locally running on your system (:1) should really make no difference.

Method #1 - VNC

You could setup VNC on the 2nd X server and then run vncviewer :1 from the 1st X desktop.

Method #2 - XDMCP

If you want to remote display an entire desktop from one system to another system you'd typically use XDMCP. You can then use a tool such as Xephyr to connect to your 2nd X server on display :1 from the 1st X server.


$ Xephyr -ac -br -noreset -screen 800x600 :1

Here are several resources for setting up XDMCP and going further.
