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

经过进一步测试，如果我只有一台或两台显示器连接到一块显卡，我就有Unity3D工作的字体。 如果我将单个显示器连接到每个显卡，Unity3D将无法工作，它将下降到Unity2D。 如果我连接3个显示器，即卡1上的2个显示器和卡2上的1个显示器，它将下降到Unity2D。 如果我将每个卡连接2个监视器，它再次下降到Unity2D。
所以Unity3D似乎只适用于单个显卡……
怎么解决这个问题？
在Unity 3d中尝试使用多个显示器时，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.我认为它与合成完成有关与compiz。 要显示我的两台显示器，我必须一个接一个地放置。
如果你想要Unity 3D，它可能适合（并且有用）上面有两个显示器，下面有两个显示器吗？
