Compiz Fusion / No Window manager

[gatekeeper]

I have installed compiz fusion and whenever I enable Xgl in order to be able to use the Compiz features, when I login back to linux (after reboot) I do not have any window manager. (meaning, I do not have those frames around the windows which close, minimize, maximize, and resize a window)

What should I do?

When I enable Xorg again through Yast, everything is back to normal, the Kde window decorator is back again, but I dont have the Compiz functionality with the effects (the rorating cube, woobly windows etc..)
