Um... When I ran the program, it said this:
Gathering information about your system...

 Distribution:          Ubuntu 10.10
 Desktop environment:   GNOME
 Graphics chip:         nVidia Corporation NV11DDR [GeForce2 MX200] (rev b2)
 Driver in use:         nouveau
 Rendering method:      None

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

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

At least one check had to be skipped:
 Error: No rendering method in use (AIGLX, Xgl or Nvidia)
Is that bad? :s
