how to run/start graphical programs (Ex: firefox) on a remote machine using CLI without logging in

So, the story is like this:

I have 2 linux machines with ubuntu 20.04 installed on both. one of them, call it computer A doesn't have X on it because it is the server version installed and I don't want to install it.

So I am connecting to computerB from computerA via SSH. ComputerB is not logged in and I don't want to log onto it graphically/visually.

But what I am trying to achieve is start a program on computerB while I am connected via ssh from computerA.

I have found that Xvfb works for me in doing what I want but I don't understand why do I need it. Is there no other way except installing this test X server ? Sorry for my ignorance, I am a novice in X matters.

Solution

  • It seems like using Xvfb is the only option since not logging in is not desired/ an option.
