在Linux中使用许多监视器（4+）

12

我希望能够运行4台以上的显示器（也许是6台），这与Displayport卡现在兼容的东西非常令人困惑。现在我有一个只有2个HDMI输出的ATI卡。我看到的问题是ATI驱动程序说它不支持4个以上的显示器。因此，看来他们的宽容度卡可能比它的价值更麻烦。

无论如何，我还是更喜欢nvidia，他们似乎总是有非常好的linux驱动程序。但是我看不到他们提供的卡具有4个以上的端口。我见过的大多数高端卡都有2个HDMI，1个DVI和1个Displayport。我是否误认为这些卡仅限于4个显示器？

那司机呢？如果我得到双nvidia卡并连接起来，比如说每张卡上有2个HDMI端口+ DVI端口，那么xorg / nvidia驱动程序会发挥出色吗？我可以设置不同分辨率的显示器吗？（我现在有2个1920x1080和1920x1200屏幕）？

x windows呢？您可以为6个屏幕设置xinerama吗？还是使其能够拖动x窗口？

更新：看来ati驱动程序最近已经走了很长一段路，并且官方支持Linux的Eyefinity。我想我要去买ATI 5870，然后看看我会在哪里弄乱它。

Update2：
我订购了5870，我会让你们知道它的运行情况。不过，目前我只有几个显示器可以玩。

你有没有建造东西？我曾经玩过三台显示器，但是缺少硬件加速。

抱歉，我有点忘记了这个问题。我得到了我的5870。驱动程序工作正常。我可以运行2台显示器（dp至HDMI），一切正常。3台显示器（全部使用dp到HDMI）无法正常工作（按预期）。我还没有获得任何显示端口监视器。我相当确定它会起作用

x windows呢？您可以为6个屏幕设置xinerama吗？还是使其能够拖动x窗口？

当前的Xorg限制为16个显示设备，但是除非您需要单独的逻辑显示（不是Xinerama样式），否则通常将多头卡视为单个设备。

我设法让Debian 6使用3x gfx卡和6个屏幕。但是，xinerama没有3D支持。
