xinerama，2 张卡，3 个显示器

我一直在努力把这件事做好，而且我已经很接近了，但还不够。这台机器有一个 Intel 适配器和一个显示器，还有一个 ATI 适配器和两个显示器。我很高兴使用 xinerama 来实现此功能。

这是我的 xorg.conf (Ubuntu 12.04):-

    Monitor         "Dell2"

    EndSubSection

所有三台显示器均为 1280x1024 戴尔显示器。有了这个，我就可以让所有三个监视器都处于活动状态。连接到 Intel 的那个（最右边）是主要的

办公桌上的物理布置：

[ Dell 3 ] [ Dell 2 ] [ Dell 1 ]
{      ATI          } {  Intel }

X 服务器布局：

[Dell  2 ]          ] [ Dell 1 ]
[     Dell 3        ] [        ]

我的意思是，如果您从 Dell 1 上的 RHS 开始，然后向左移动，您将跳转到下一个 Dell 3。 Dell 3 显示的虚拟尺寸为 2560，当您点击它的左边缘时，它开始平移。此时，您也会出现在 Dell 2 上，当您到达最左侧边缘时，Dell 3 和 2 会显示相同的内容。

如何使显示器正确布局？

非常感谢！

约翰

编辑：-

尝试了这个，并且再次几乎有效。如果没有“主要”选项，我会在 Dell1 上获得 Unity，而在其他设备上出现黑屏（但鼠标会移动）。使用“主要”选项时，我没有得到 Unity，所有显示器上的背景都会闪烁，按下按键时显示闪烁，而且通常非常奇怪。

我不确定这是否有帮助 - 但我在使用双头配置的 CentOS 上也遇到了一些问题。

最终起作用的是：

Section "ServerLayout"
        Identifier     "Multihead layout"
        Screen      0  "Screen0" LeftOf "Screen1"
        Screen      1  "Screen1" 0 0
        InputDevice    "Keyboard0" "CoreKeyboard"
        Option      "Xinerama" "on"
        Option      "Clone" "on"
EndSection

对于监视器（两个相同的监视器），我只留下一个模型行并注释掉同步和刷新行：

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Dell 1905FP (Digital)"
 ### Comment all HorizSync and VertSync values to use DDC:
#       HorizSync    30.0 - 81.0
#       VertRefresh  56.0 - 76.0
        Option      "dpms"
        Option      "xrandr"
        Modeline "1280x1024" 108.00  1280 1328 1440 1688  1024 1025 1028 1066 +hsync +vsync
EndSection

Section "Monitor"
        Identifier   "Monitor1"
        VendorName   "Monitor Vendor"
        ModelName    "Dell 1905FP (Digital)"
 ### Comment all HorizSync and VertSync values to use DDC:
#       HorizSync    30.0 - 81.0
#       VertRefresh  56.0 - 76.0
        Option      "dpms"
        Option      "xrandr"
        Modeline "1280x1024" 108.00  1280 1328 1440 1688  1024 1025 1028 1066 +hsync +vsync
EndSection

显卡是双头 ATI（我认为与您的相当）。请注意设备部分中的“screen”参数。

Section "Device"
        Identifier  "Videocard0"
        Driver      "r500"
        BusID       "PCI:3:0:0"
        Option      "xrandr" "True"
        Screen      0
EndSection

Section "Device"
        Identifier  "Videocard1"
        Driver      "r500"
        VendorName  "Videocard Vendor"
        BoardName   "ATI Technologies Inc RV610 [Radeon HD 2400 XT]"
        BusID       "PCI:3:0:0"
        Option      "xrandr" "True"
        Screen      1
EndSection

现在将所有内容放在一起显示屏幕 - 再次 - 我不允许选择分辨率，不得不强制使用 24 位：

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1280x1024"
                Virtual 1280 1024
        EndSubSection
EndSection

Section "Screen"
        Identifier "Screen1"
        Device     "Videocard1"
        Monitor    "Monitor1"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1280x1024"
                Virtual 1280 1024
        EndSubSection
EndSection

在KDE中我是这样设置的：

  • 为多个显示器启用虚拟工作区
  • 监视器1：x=0，y=0，宽度=1280，高度=1024
  • 监视器2：x=1280，y=0，宽度=1280，高度=1024
