Ibm x30 花屏问题 （830M显卡）

[AlphaChio]

Xorg.0.log 如下：
(II) intel(0): Creating default Display subsection in Screen section
"Default Screen" for depth/fbbpp 24/32
(==) intel(0): Depth 24, (==) framebuffer bpp 32
(==) intel(0): RGB weight 888
(==) intel(0): Default visual is TrueColor
(**) intel(0): Option "ForceEnablePipeA" "true"
(II) intel(0): Integrated Graphics Chipset: Intel(R) 830M
(--) intel(0): Chipset: "i830"
(--) intel(0): Linear framebuffer at 0xD8000000
(--) intel(0): IO registers at addr 0xC0000000
(II) intel(0): 2 display pipes available.
(==) intel(0): Using EXA for acceleration
(II) Loading sub module "int10"
(II) LoadModule: "int10"

xorg.conf 配置如下：
Section "Device"
Identifier "Configured Video Device"
Option "ForceEnablePipeA" "true"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

现在有很严重的花屏现象，应该如何配置？
