Linux Mint 17.1 在双显示器模式下无法工作

我在 Linux Mint 17.1 设置中无法使双显示器设置在工作。

系统菜单下有一个显示应用程序，当我运行它时，它显示我有两个显示器（它甚至知道每个显示器的品牌！）。问题是，如果我将应用程序设置为镜像显示以外的任何显示，两个显示器中的一个会变黑。我使用的是双显示器视频卡。我没有添加任何驱动程序，只是安装了最新的 Linux Mint。

输出如下lspci：

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] R520 [Radeon X1800 XT]
01:00.1 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] R520 [Radeon X1800] (Secondary)

    ## This is the layout for the X server
    Section "ServerLayout"
        Identifier  "Default Layout"
        Screen  0   "screen1" 0 0
        Option "Xinerama" "0"
    EndSection

    ## This defines your graphics card, there should
    ## only be ONE such section for each card.
    Section "Device"
        Identifier     "device1"
        Driver         "radeon"
        BusID          "PCI:1:0.0"
   ## Twinview lets you have one big desktop 
   ## shared between the screens
        Option     "TwinView"
   ## This is where you need to findthe names of your two monitors
   ## and edit the line below accordingly. This is what I have
   ## on my system:
        Option         "metamodes" "DP-3: 1600x900, VGA-0: 1440x900, DP-2: 1920x1080, DP-1: 2560x1024"
        Option         "TwinViewOrientation" "RightOf"
        Screen         1
   EndSection

   ## I don't think these sections do anything unless you
   ## Identify the monitor somehow, they can probably be removed.
   Section "Monitor"
        Identifier     "monitor1"
   EndSection
   Section "Monitor"
        Identifier     "monitor2"
   EndSection

   ## This is where you define a single screen that stretches 
   ## across both moitors.
   Section "Screen"
        Identifier     "screen1"
        Device         "device1"
        Monitor        "monitor1"
        SubSection     "Display"
            Depth       24
        EndSubSection
   EndSection
