"Tired of a looking at a flat, bland desktop? It's time for some
eye candy, Compiz-style. Using Compiz you can enable all sorts of
fantastic desktop effects and attractive themes. Want to spruce up
your machine with 3D eye candy? Read on to enable Compiz, manage
your workspaces with a 3D cube, and help yourself to the Emerald
collection of Compiz themes.
"Of course before we can get to those super cool effects, we
have to get Compiz installed on your desktop. And that is what this
tutorial is all about — installing Compiz.
"Before you can install Compiz, you have to make sure you have
the hardware that will power compositing. Finding an "official
minimum requirements" list is a bit of a challenge. But I will say
that most modern desktop machines should be powerful enough to use
Compiz. If you already have Linux installed, and you're using the
GNOME desktop, a good way to check is to click System >
Preferences > Appearance. In this new window click on the Visual
Effects tab and select either Normal or Extra. If all of a sudden
your desktop seems to have a few extra effects (like Wobbly
Windows) you're good to go."
