配备两个 Nvidia GPU 的双显示器

我有两台 gtx 275s SLI，当我将两台显示器连接到同一张卡时，它允许我启用双屏显示，并且它可以正常工作。但是当我想将每台显示器连接到不同的卡时，我失去了双屏显示选项，我的辅助屏幕只是白色的，当我将鼠标悬停在它上面时，我的鼠标变成了 X。

请参阅专有 nvidia 驱动程序文档的第 29 章。对于仅有两个显示器的情况，nvidia 似乎建议使用 twinview，将两个显示器连接到一张卡，因为这种配置似乎能给您带来最佳体验。

选择从官方网站下载 Linux 驱动程序时，您可以找到该文档。它是附加信息选项卡中的 README 链接。

或者使用 Unix 相关页面，并确保使用与您的驱动程序版本和体系结构相匹配的文档： http://www.nvidia.com/object/unix.html
