Try adding this to the bottom of your /etc/X11/xorg.conf:
Code:
Section "Extensions"
    Option         "Composite" "enable"
EndSection
You should also make sure that DRI is enabled. Post the output of `glxinfo | grep direct`.

i did xorgconfig and i got the same error.

i then added the composite enable line and got this:

Code:
root@236linuxbox:~# compiz
compiz (core) - Error: Screen 0 on display ":0.0" already has a window manager; try using the --replace option to replace the current window manager.
compiz (core) - Fatal: No manageable screens found on display :0.0

You'd also need a new window decorator unless you can live with unresizable windows.

This is what I use if I want to start compiz on the spot:
Code:
#!/bin/bash
# Compiz startup script

LIBGL_ALWAYS_INDIRECT=TRUE \
/usr/bin/compiz --replace png svg decoration annotate water blur clone \
  wobbly fade minimize cube rotate zoom scale move resize place switcher &
/usr/bin/kde-window-decorator &
As you can see, I use KDE, for which there is a compiz window decorator. There is a GTK alternative too.
Setting LIBGL_ALWAYS_INDIRECT to "TRUE" is not needed for all graphics drivers. You'll find out soon enough.

snakeapple, you must enable direct rendering (DRI) in order to get compiz working, as far as I know. Your output shows that direct rendering is disabled. What video card are you using? What drivers are you using for that video card?
