Can I get Compiz running on openSUSE?
Sure. Compiz is available in the Build Service. Plugins and settings tools are Compiz-Fusion; for a guide on setting Compiz up, see Compiz. Recent releases of Compiz can be found on Build Service repositories. There is a guide and more information on Compiz available at Compiz. If you use KDE 4, you should use the native composite manager KWin.
