In Ubuntu 12.04 (Precise Pangolin) with Unity, Alt + Tab lets you switch between groups of windows and makes it very annoying to switch to a specific window from a group when it is not the last window used.
One way to change this behaviour and get a plain Alt + Tab switcher showing all windows (without grouping) is to install ccsm (Compiz configuration settings manager), and enable the "static switcher" or something similar (can't remember exactly).
I need to modify this setting on several machines, so I don't want to install a complex package for this. (Particularly not when this package makes it easy for users to completely f*k up their system when changing the wrong settings).
So I'm looking for a reliable way to change this configuration, through one or more commands (gconftool?), or by modifying a configuration file directly.
Basically, I want to do directly on other machines what ccsm once did on mine to restore a sane and simple Alt + Tab behaviour.
