I found that the dri had been disable, even though I have Option  
"AGPMode" "4",
is there anywhere I could solve this problem? Or what should I check to 
clarified this problem?

AND, also I had try to use ATI fglrx driver, which have dri on dual-head 
mode,
but the output of 2nd-screen is a totaly mess, any icons, any details on 
the 2nd-screen are unreadable,
and when the mouse move on 2nd-screen, I just see a bunch of color 
pixels moving. 
The xorg.conf is configured by fglrxconfig.

Clone-mode on both driver do have dri, but too bad, I don't know how to 
let 1st-screen with 1400x1050
while 2nd-screen at 1024x768.

Thanks to any comment.
