With the same hardware I get the same error under Ubuntu 13.10, but not under Arch Linux using Mesa 9.2 nor Mesa 10; it may be an Ubuntu 13.10 specific bug.
I was using the DefaultDepth set to 24, and by default the intel DDX driver is defaulting to 15/16 when using SNA (in UXA it is 24). xiangxw, try changing the DefaultDepth to 24, I think it should fix the problem. Section "Screen" Identifier "Screen0" DefaultDepth 24 EndSection Composition doesn't seem to work either with the default settings. Wouldn't it be better to set the driver to use a DefaultDepth of 24 by default?
The default depth should be set to 24 by the driver, the manual override is a workaround.
This is already the case since 2.99.908 (2014-02-01). http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=539b749416b275d84e05e2a5b62d946903aa3d29
