xorg.conf 和 Unity3D？

由于某种原因，我似乎无法将 Unity3D 与以下 xorg.conf 文件一起使用：

目前，如果我选择 Unity3D，它只会显示在 1 个屏幕上，如果我选择 Unity2D，它会将 1 个屏幕镜像到所有屏幕，所以我不得不求助于 gnome-classic 来让所有 4 个屏幕与上述 xorg.conf 一起工作。

经过进一步测试，我发现如果只将 1 或 2 个显示器连接到单个显卡，Unity3D 就可以正常工作。如果我将单个显示器连接到每个显卡，Unity3D 将无法工作，它会降为 Unity2D。如果我连接 3 个显示器，即卡 1 上有 2 个显示器，卡 2 上有 1 个显示器，它会降为 Unity2D。如果我将 2 个显示器分别连接到每个显卡，它会再次降为 Unity2D。

所以看起来 Unity3D 只适用于单张显卡......

如何修复此问题？

答案1

在 Unity 3d 中尝试使用多台显示器时，我发现显示器显示的虚拟桌面的最大宽度不能超过 2048。我认为从上到下的最大值也是 2048。我认为这与使用 compiz 完成的合成有关。为了显示我的两台显示器，我必须将它们一个接一个地放置。

如果您想要 Unity 3D，那么在上面有两个显示器、在下面有两个显示器是否合适（并且有帮助）？
