I tried to get Compiz working on my Xubuntu 8.10 according to this guide. I tried both what is described as the easy way and the hard way. The problem is that non of them works for me.

What is described as the hard way is making it default using this comand and then changing the start alternative:
gksudo "mousepad /etc/xdg/xfce4-session/xfce4-session.rc"

the easy way is just adding compiz in to the autostart apps. I wonder is there a third way, preferably with doesnt slow down the computer.
