DisplayLink 显示器与英特尔一起

我有一个 USB DisplayLink 设备，可以使用自定义 Xorg 配置文件。由于安装了 saucy X 服务器和内核，我正在使用 saucy 的 X 服务器运行 Ubuntu 12.04 amd64：

sudo apt-get install --install-recommends xserver-xorg-lts-raring

我正在运行以下内核和 X 版本：

X.Org X Server 1.14.5

核心：

3.11.0-20-generic

我目前遇到的问题是无法同时使用外部 DisplayPort 和外部 USB DisplayLink 显示器。我可以用任何一个USB DisplayLink 显示器或者DisplayPort 显示，但不能同时显示。

这是我的 /etc/X11/xorg.conf 文件：

Section "ServerLayout"
        Identifier      "Server Layout"
        Screen  0       "DisplayLinkScreen" 0 0
        Screen  1       "DefaultScreen" LeftOf "DisplayLinkScreen"
        #Option          "Xinerama" "On"
EndSection

Section "Device"
        Identifier      "Configured Video Device"
        Driver          "intel"
EndSection

Section "Monitor"
        Identifier      "Configured Monitor"
EndSection

Section "Screen"
        Identifier      "DefaultScreen"
        Monitor         "Configured Monitor"
        Device          "Configured Video Device"
        #DefaultDepth    16
        SubSection "Display"
                Depth   16
                Modes   "1920x1080"
        EndSubSection
EndSection

Section "Device"
        Identifier "DisplayLinkDevice"
        driver  "fbdev"
        Option  "fbdev" "/dev/fb1"
EndSection

Section "Monitor"
        Identifier      "DisplayLinkMonitor"
EndSection

Section "Screen"
        Identifier      "DisplayLinkScreen"
        Device          "DisplayLinkDevice"
        Monitor         "DisplayLinkMonitor"
        #DefaultDepth    16
        SubSection "Display"
            Depth   16
            Modes   "1920x1080"
        EndSubSection
EndSection

这个想法很简单，就是拥有一台双显示器机器。关于为什么无法启动两个显示器的任何想法？目前，通过上述设置，它仅运行 DisplayLink USB 显示器，Intel 显示器仅显示控制台输出。
