Deal all,

I am configuring double screens display with lx800 in linux now. I used the driver as  vesa + vesafb , the two screens displayed funy in x-system.  But if  I  used the driver as amd + lxfb,  the system died after start x-system.  My kernel version is 2.6.24.  Both lxfb and amd drivers can run well solely.  Is there anyone can tell me how can I do?  I tried as amd+vesa, amd+vesafb... almost all the selection, but none of them can do well.  Here is my xorg.conf, Please help me. Thanks.
