A big bonus with Linux desktops is that you can use multiple workspaces to separate out your work.
Ubuntu also comes with its own virtual desktops called Workspaces. You can create multiple workspaces which act like virtual desktops.
If you keep a lots of apps open at once and you want to separate them by tasks, using workspaces may be useful. Workspaces can be used to organize your work to reduce clutter and make your desktop easier to navigate.
To use workspaces, click Activities on above the vertical bar (dock), then move your cursor to the right the screen to show the active workspaces plus one empty one.
To add a workspace, drag and drop a window from an existing workspace onto the empty workspace in the workspace selector. This workspace now contains the app you have dropped, and a new empty workspace will appear below it.
To remove a workspace, simple close all its windows or move them to other workspaces.. there is always at least one workspace. This is the workspace selector.
You can also move apps from one workspace to another by simply dragging and dropping the apps onto the other workspace. This workspace now contains the apps you have dropped, and a new empty workspace appears at the bottom of the workspace selector.
