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?
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!
You can change this behaviour by executing:
$ gsettings set org.gnome.mutter workspaces-only-on-primary false
sudo apt install dconf-editor
Disable following settings:
dconf write /org/gnome/mutter/workspaces-only-on-primary false dconf write /org/gnome/shell/overrides/workspaces-only-on-primary false
To get up and running all the gnome extensions config directly in your browser, you only need the following.
You can install
sudo apt install gnome-tweak-tool.
Then go to Workspaces > Display Handling > And choose Workspaces span displays
