Is it possible (and if so, how) to have a terminal open on x-screen 1, execute a command on that terminal, and have an application open on screen 2?

Question

Let's say you have two monitors hooked up to the same machine, running gnome (let's call them 'A' and 'B'). Each has its own, independent x-screen.

Our goal is to type a command into a terminal on Monitor A and have that command open an application on Monitor B.

Is there an easy X-command that lets that happen?

Answer 1

Assuming the first display is :0 and the second is :1 then typing

DISPLAY=:1 <command>  

should be enough to get the command to run on the second window.

This will make all subsequent apps run from the terminal session open in the second window:

export DISPLAY=:1
