如何安装第二张显卡并使用 4 台显示器？

我最终决定大胆尝试，放弃 Windows。几个小时后，我安装的所有应用程序都完美运行。唯一的问题是，我用 2 个 nvidia 适配器运行 4 个桌面显示器，第一个适配器 (GeForce GT 240) 有两个屏幕，运行正常，但似乎无法安装第二个适配器 (GeForce GT 620)。使用 Ubuntu 14.04 LTS (AMD64)

请帮我提供一些简单的说明。以下是终端信息：

这很困难我在 Linux Mint 64 上使用四台显示器，这是我的/etc/X11/xorg.conf。

还使用 Ubuntu0.0.4 nvidia-331 .113 推荐的二进制驱动程序

也许会有帮助，因为这是最难得到的东西
