Black Display Freezing after a while

[sherl]

Hi,

I've installed with succes the new 8.31.5 ATI driver on my fc6.
It works perfectly on my laptop Dell 610 with X300 graphical card.

Problem is when i, plug an external display + "a big display" xorg.conf my computer just freezes after a while (before this freeze it works fine).

I've got the following message into the /var/log/Xorg.0.log file.
(II) fglrx(0): [drm] removed 1 reserved context for kernel
(II) fglrx(0): [drm] unmapping 8192 bytes of SAREA 0xd000 at 0xb7e95000
(EE) fglrx(0): === [swlDalHelperSetControllerConfigForRemap] === CWDDC ControllerSetConfig failed: 6 - 0

Here is the copy of my dual display (big display) config file (/etc/X11/xorg.conf):
