There is a great script created to check whether your system is compiz ready or not. It’s called Compiz-Check.

Gathering information about your system...

 Distribution:          Ubuntu 8.04
 Desktop environment:   GNOME
 Graphics chip:         nVidia Corporation G70 [GeForce 7300 GT] (rev a1)
 Driver in use:         nvidia
 Rendering method:      Nvidia

Checking if it's possible to run Compiz on your system...

 Checking for texture_from_pixmap...               [ OK ]
 Checking for non power of two support...          [ OK ]
 Checking for composite extension...               [ OK ]
 Checking for FBConfig...                          [ OK ]

Checking for hardware/setup problems...            [ OK ]

If you got [ OK ] in every check, like mine, then your system is ready to run compiz. If something fails, go check the forum
