Using Lubuntu 16.04 LTS. Was working perfectly.
Then I installed the following dependencies:
lsb-base lsb-core lsb-invalid-mta
Then installed the latest version of Google Earth for the OS from .deb
Decided to un-install GE which I did using Synaptic.
When I rebooted, my workspaces that had previously been in the taskbar were missing.
Went into Openbox Config (obconf) Workspace option is still there along with the three workspaces that were there before GE was un-installed.
How do I get the workspaces back into the taskbar where they originally were?
UPDATE: Curiously enough, it is simply the visual representation of the workspace that is missing from the taskbar, i.e. the launcher shortcut. If I use keyboard shortcut Superuser + f1/f2/f3, it switches to the appropriate workspace.
