Change workspaces layout in Unity 2D
I want to change the desktops/workplaces from 2x2 to 5x1 but it is not possible using CCSM (CompizConfig) nor MyUnity.
I've tried to use gconf-editor, by changing the value of the key apps > metacity > num_workspaces to 5, but it gets 3x2 without the last (sixth) desktop/workplace.
Does any one know how to do it on Unity 2D? On Ubuntu 12.04.
