I checked the Xorg.0.log again, and found xorg identified Intel GMA 4500 as vesa by itself, so it load vesa driver. With the vesa driver, compiz could not work. After I modied xorg.conf manually to force load intel driver, compiz worked. :) Thank you!
But it looks as that the support to Intel GMA 4500 of xserver-xorg-video-intel is not fine. There are some mistakes with it.
