如何让 Xorg 处理两个设备的 fglrx 和 intel？Xorg 出现段错误

Question

我正在尝试通过利用连接到 AMD 卡的主显示器和连接到主板 VGA 插槽的辅助显示器来实现多显示器设置。计算机启动后，两个显示器都显示黑屏。只有当我为“Intel-gfx”指定英特尔驱动程序时才会发生这种情况，如果是其他名称，则什么也不会发生，但第二个屏幕当然是黑屏。

我在运行 Ubuntu 14.04 LTS X.Org X Server 1.15.1 的台式机上执行此操作，我不确定要在此处输入哪个 gfx 驱动程序版本。我忘了安装的是哪一个。主板：GA-Z87X-D3H Gfx 卡：AMD R9 290

这是我的 xorg.conf：
