Error: cannot open display: :0.0 - Red Hat Enterprise Linux Server

Question

I am trying to open up firefox in my Red Hat machine. I am doing,

export DISPLAY=:0.0

and typing,

firefox

I am getting

Error: cannot open display: :0.0

Is there any way to know what packages are missing or needs to be installed or any log files I can refer to, to be able to load firefox from terminal.

@agc, I am not sure if Xvfb is running in my system and if it is running what display number it is using. Is there a quick way to find this? I don't want to randomly paste commands from the internet into my machine :) — Chuchoo, Nov 09 '16 at 14:39

Ok. I figured it out. I had to use X11 forwarding using Xming. Below link provides more details.
