如何在 Linux Mint 15 上运行 3 个显示器（2 个视频卡）？

我正在尝试将我的 PC 从 Windows 切换到 Linux Mint 15。我有三个显示器，它们在 Windows 下运行良好。安装 Mint 后（发现它自然只使用 1 个显示器），我尝试使用“显示”添加另外两个显示器；但是，这样做并不能利用我的两个 Nvidia GeForce 9600 显卡。屏幕反复闪烁，整个系统变慢。我已使用sudo apt-get install nvidia-current 并下载并运行 Nvidia 提供的“NVidia...run”文件安装了 nvidia 驱动程序。然后，使用 nvidia Server x 配置启用了另外两个显示器。每当我执行此操作并重新启动 x 服务时，所有三个显示器都会启用，但 Cinnamon 会反复崩溃（留下一个奇怪的、无法使用的桌面，其中所有托盘图标和菜单在主显示器上重复三遍）。

我怎样才能让所有 3 个显示器工作（一个桌面跨越三个显示器）？

我尝试过到处搜索，虽然很多地方都多次讨论过这个问题，但这些讨论都不是最新和全面的（而少数接近的讨论也导致了上述结果）。

我将添加该问题所需的任何信息。

我花了几个星期尝试在我的机器（HP XW8400，配有 2 张相同的 NVS 290 卡）上实现这个功能，但无济于事。最后我切换到了 KDE，一切正常。我肯定这不是你想听到的，但请试一试：

在 NVIDIA 工具中，您需要启用所有 3 个显示器。您目前只能使用单独的 X Screen 启用它们，并选中 Xinerama。这实际上不会得到您想要的结果，但它将允许以下命令工作。

sudo nvidia-xconfig --separate-x-screens --render-accel --xinerama

如果出现错误，请确保三个命令选项前面有双破折号。输出应如下所示：

user@host:~$ sudo nvidia-xconfig --separate-x-screens --render-accel --xinerama

Using X configuration file: "/etc/X11/xorg.conf".
Option "RenderAccel" "True" added to Screen "Screen0".
Option "RenderAccel" "True" added to Screen "Screen1".
Option "RenderAccel" "True" added to Screen "Screen2".

WARNING: The Composite X extension does not currently interact well with the
         Xinerama option; the Composite X extension will be disabled.

Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
New X configuration file written to '/etc/X11/xorg.conf'

再次，我无法让它在 Cinnamon 上运行（即启动到“故障回复模式”）。试一试，看看会发生什么。
