升级至 11.10 - 四显示器问题

我在设置我的机器以使用四显示器时遇到了问题。在 11.04 中一切都运行良好，但自从升级以来，我一直无法让配置正常工作。如果我使用与 11.04 中相同的 xorg.conf，我会在显示器上看到 4 个相同图像的克隆。不仅如此，如果我单击启动栏中的图标（例如 Firefox），X 会重新启动。让两个显示器工作很简单，如果我只需删除 xorg.conf，Ubuntu 就能检测到这两个显示器并正确设置它们。

我并不关心任何花哨的效果，但如果我能像以前一样使用四台显示器启动并运行系统，那就太好了。我没有使用 ati 驱动程序，只使用开源 radeon 驱动程序，因为我的一张卡不受较新的 ATI 驱动程序支持。我在系统上使用两张不同的 ATI 卡：

01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series]
02:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3600 Series

xorg.conf如下所示：
