Intel iMac Dual-boot leopard/ubuntu

[computergeek6]

I have the system installed and booting, but when I load Ubuntu, the screen seems like each line of pixels is offset from itself. It looks like this:

XXX________XXX
________XXX________XXX
XXX________XXX
________XXX________XXX
XXX________XXX
________XXX________XXX
XXX________XXX
________XXX________XXX
___XXX XXX
________XXXXXXXX
"X" = On Pixel
"_" = Off Pixel

Does anyone know what's wrong?

EDIT: Never mind. I had to install the proprietary video drivers

How do I get Compiz Fusion working?

There are plenty of tutorials online that can help you install it via the terminal, but I just used synapic to install it.

I have it installed, but it doesn't do anything once I start it, then if I close it, it makes the system go crazy.
