Question

I would like to run a window/X program from SSH but using server’s own X Display for the window rather than client’s X Display. How to do that? Please not that I am not asking for X Forwarding here.

I tried this in SSh after connecting to server,

DISPLAY=:0.0

DISPLAY=:IP_I_dont_want_to_do_this because it might use public ip under-the-hood

What is the best way to do this?

For further information I am using Amazon EC2 Ubuntu instance.

Google suggest me “xpra”, which looks “screen” for X window but I am intented to run application fully on X Display of the server.

Answer 1

You should be able to run a X client (e.g. xterm) under default Xserver like this

DISPLAY=:0 xterm

If above not works, try ps aux|grep /usr/bin/X to find which DISPLAY port your Xserver is using
