Questions[workspaces](ubuntu)

Any idea how to have more than 2 workspaces on Ubuntu 18.04.1?

Dual monitor setup on Ubuntu 18.04; when I hit activities only the left monitor switches workspaces while the right monitor just keeps whatever is on its screen. Is there a way to make the workspace span both monitors so that when I switch from one workspace to another both monitors switch?

Problem description

I really like the 2 by 2 workspaces in Ubuntu 16.04. But it seems I can only shift workspace up and down.

Is there a way to achieve this?

What I have tried

Tried the GNOME extension called Workspace Grid (suggested here: Can I have 2x2 workspaces in GNOME 3?), however, it does not work because when I tried to install it, I cannot find installation extension in the GNOME Tweaks.

I heard something about having multiple work spaces on Ubuntu 14.04 and was curious about it.

I normally use 4 different workspaces for different things, and they are always the same. Can I make a different background image for each one of them?

I would like an answer that works for GNOME 3 desktop environment, Unity and the Classic desktop environment.
