Ubuntu 16.04 – Workplace Switcher Stopped Working

keyboardshortcut-keysunityworkspaces

I was using workplace switching for a long time and it suddenly stopped working today. Even after a fresh install, (some config left over as I preserved my /home folder).

Super + S still raises to show all work-spaces.

Clicking on a task-bar icon representing a window in another work-space no longer switches to that workspace + window.

Ctrl + Alt + (any direction) no longer works.

Ctrl + ShiftAlt (any direction) no longer works.

I've verified that those key combos are registering by redundantly re-assigning the shortcut mappings.

Did another search today and found this: Can't switch workspaces

The advice to go to Compiz ccsm and activate Desktop Wall fixes the problem immediately.

What a relief !
