在 Linux 中使用多个显示器 (4+)

我希望能够运行 4 个以上的显示器（也许是 6 个），但现在与即将推出的 Displayport 卡兼容的显示器非常令人困惑。现在我有一张 ATI 卡，只有 2 个 HDMI 输出。我看到的问题是 ATI 驱动程序说它不支持超过 4 个显示器。所以看来他们的 Eyefinity 卡可能比它的价值更麻烦。

无论如何，我更喜欢 nvidia，他们似乎总是有非常好的 Linux 驱动程序。但我没有看到他们提供超过 4 个端口的卡。我见过的大多数高端显卡都有 2 个 HDMI、1 个 DVI 和 1 个显示端口。我是否误认为这些卡仅限于 4 个显示器？

那么司机呢？如果我获得双 nvidia 卡并在每张卡上连接 2 个 HDMI 端口 + DVI 端口，xorg/nvidia 驱动程序会运行良好吗？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 窗口怎么样？您可以为 6 个屏幕设置 xinerama 吗？或者让它能够拖动x窗口？

更新： 看来ati 驱动程序最近已经取得了长足的进步，并且官方的eyefinity 支持linux。我想我会去买一块 ATI 5870，看看我能在哪里弄乱它。

更新2：
我订购了 5870，我会让你们知道它的情况。不过，我目前只有几个显示器可以玩。

答案1

x 窗口怎么样？您可以为 6 个屏幕设置 xinerama 吗？或者让它能够拖动x窗口？

当前的 Xorg 限制是 16 个显示设备，但多头卡通常会被视为单个设备，除非您需要单独的逻辑显示（不是 Xinerama 风格）。

答案2

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