Dual monitor workspaces in Ubuntu 18.04

Question

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?

Answer 1

Had the same problem. Turned out it was super easy to fix.

Install the GNOME Tweaks app. Go to Workspaces and set Display handling to Workspaces span displays. Done!

Answer 2

You can change this behaviour by executing:

gsettings set org.gnome.mutter workspaces-only-on-primary false

Answer 3

You can install gnome-tweak-tool via sudo apt install gnome-tweak-tool.

Then go to Workspaces > Display Handling > And choose Workspaces span displays

Answer 4

In Ubuntu 22.04:

Settings > Multitasking > Multi-Monitor > Workspaces on all displays

Answer 5

Install dconf-editor:

sudo apt install dconf-editor

Disable the following settings:

dconf write /org/gnome/mutter/workspaces-only-on-primary false
dconf write /org/gnome/shell/overrides/workspaces-only-on-primary false

Answer 6

I recommend to you to use the Multi Monitos Add-on extension, available in GNOME Extensions. It is pretty easy to use, and it also gives you the ability to add a panel in the second monitor.

To get up and running all the GNOME extensions config directly in your browser, you only need the following:

1. Install the gnome-shell-extensions package:

   sudo apt install gnome-shell-extensions
   

2. Install the host connector:

   sudo apt install chrome-gnome-shell
   

3. Install the GNOME Shell integration extension (Chrome) or add-on (Firefox).

4. Find and install the Multi Monitos Add-on extension.

Answer 7

I am speaking (only) for Ubuntu 24.04 (no earlier version, no mate, no...)

NOT working: anything multi-monitors-add-on@spin83

NOT working: anything gnome-tweaks (no longer shows a Workspaces option)

INDEED working: Onboard means (regular settings)
