Ubuntu :: Running Compiz At Login Instead Of Metacity?

I would like to be able to use compizconfig-settings-manager to set some custom settings for compiz, and then have compiz be the window manager that runs when I log in. The trouble is that I cannot seem to find a good way to have compiz run at log in. I can add "compiz --replace" to my startup programs list, but this loads metacity and then replacing it with compiz and seem to add a bit to the startup time (not to mention it seems to be slightly unreliable).

Further, I tried this: Uninstalled compizconfig-settings manager. In appearance preferences, set visual effects to normal. Everything seems to work fine until I log in again, at which point no window manager runs. Setting visual effects to none makes metacity load.
