Symptoms (on up-to-date Ubuntu 13.10 Saucy installation):
--------------------------------------------------------
* Default 2x2 workspaces are enabled (Workspace switcher icon in Launchbar):
(System settings > Appearance > Behaviour : Enable workspaces)
* Can navigate between workspaces using Workspace switcher in Launchbar or
the Super+S key and arrow keys
* Workspace navigation defaut shortcuts are apparently defined:
(System settings > Keyboard > Shortcuts > Navigation)
Eg 'Switch to workspace right' is shown as 'Ctrl+Alt+Right'
but this key combination does not have any effect.
Solution / workaround:
----------------------
* Install ccsm package:
$ sudo apt-get install compizconfig-settings-manager
Run the compiz settings program:
$ ccsm
* You should see that 'Desktop Wall' in the Desktop section is not checked/enabled
* Enable/check 'Desktop Wall' in the Desktop section
* Exit ccsm
* Log out and log in again
* Workspace navigation keys should now work
