3 个显示器的问题

我全新安装了11.04（重新格式化等）并且我的第三台显示器有问题。我运行 2 个视频卡和默认 NVidia 驱动程序。我让驱动程序生成我的 xorg.conf，因为我还是个新手 :)

我对 2 个工作显示器没有意见。它们设置为 TwinView，这可能是也可能不是最好的，但我宁愿避免运行 Xinerama，因为我担心我将无法再使用 Unity。长话短说，同一显卡上的 2 个显示器没有已知问题。

第三台显示器似乎没有窗口管理器。我没有启动栏，没有面板，当我右键单击 -> 新建文件时，gedit 打开，没有文件 / 编辑 / 工具 ... 选项，标题栏也不可见（关闭、最小化、最大化）。如果我尝试在文本编辑器中写入任何内容，它会将文本写入另一个正在工作的屏幕之一（几乎就像屏幕上的窗口一样）第三台显示器从未获得焦点)。我的 xorg.conf 文件发布在下面——请让我知道任何其他有用的文件。我非常感谢你的建议！

答案1

我有两个显示器运行单独的 X 屏幕，其中一个是垂直的，我也遇到了同样的问题。我可以通过从主显示器上的终端发出命令来运行窗口管理器DISPLAY=:0.1 unity --replace。因此，您可以通过找出第三个显示器的标识并替换:0.1上述命令中的来启动和运行。
