How can I remove the second desktop on Lubuntu?

On Lubuntu, I have two desktops and can change between them by scrolling.

How can I completely remove the 2nd desktop? I don't want to just unassign the scroll shortcut, I want the extra desktop gone.


Open the Application menu, go to Preferences and -> Openbox Configuration Manager:

Click Desktops:

Click the - button, and you will have 1 desktop. You may then wish to remove the "Desktop Pager" in the bottom bar by right clicking on it.
