无法在 CentOS 6 中设置双显示器

Question

我需要使用二不同X11 DISPLAY的二不同的 UI 应用程序二不同的物理监视器。每个应用程序在每个监视器上。

配置：

• VDI输出：Acer K192HQL
• HDMI via VDI输出：PHL 193V5
• OS：CentOS release 6.9 (Final)

配置如下Xorg：

Section "ServerLayout"
        Identifier     "X.org Configured"
        Screen         "Screen0" LeftOf "Screen1"
        Screen         "Screen1" RightOf "Screen0"
EndSection

Section "ServerFlags"
        Option "DontZap" "yes"
        Option "BlankTime" "0"
        Option "StandbyTime" "0"
        Option "SuspendTime" "0"
        Option "OffTime" "0"
EndSection

Section "Monitor"
        Identifier   "Monitor0"
        ModelName    "LCD Panel 1280x1024"
        HorizSync    31.5 - 67.0
        VertRefresh  50.0 - 75.0
        Option      "dpms"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1280x1024"
        EndSubSection
EndSection

Section "Monitor"
        Identifier   "Monitor1"
        #ModelName    "LCD Panel 1280x1024"
        #HorizSync    31.5 - 67.0
        #VertRefresh  50.0 - 75.0
        Option      "dpms"
EndSection

Section "Screen"
        Identifier "Screen1"
        Device     "Videocard0"
        Monitor    "Monitor1"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1280x1024"
        EndSubSection
EndSection

以下是输出xrandr：

因此，正如您所看到的，我刚刚有Screen 0，但我需要两个屏幕来将每个应用程序发送到其专用屏幕（DISPLAY）。

我也在系统设置中看到此消息：

这里是个Xorg.0.log。
