If it fails to correctly detect this on you hardware, then this is a bug, and should be filed appropriately.

Compiz is the 3D window manager requiring advanced graphics cards ("Normal" and "Extra" settings). Metacity is a 2D window manager, ("None" setting) that should work practically anywhere. If you're running a graphical environment at all then you're likely running Metacity still, unless you manually switched to an alternative like Fluxbox or IceWM. All the best, Evan
