使用带有 PCIe 视频卡的板载 VGA 输出。两个 nVidia

Question

我有 2 个视频卡，一个 On board，一个nVidia 6150SE nForce 430和一个 PCIenVidia GeForce GT 220 1GB DDR2 RAM

我已经将 PCIe 卡配置为使用双显示器功能，使用 VGA 和 HDMI 端口，但现在我想添加第三个显示器，使用板载 VGA 端口

我设法启用了占用 400MB 内存的板载图形处理器，但我无法使用它，nvidia-settings没有检测到它，就像它不可用（但在那里）

我的问题如下：

1. 我怎样才能让板载 VGA 显示器与 PCIe 显卡一起工作？

2. 如果可能，我如何恢复板载卡占用的 400 MB（即使没有被使用），或者如何让它使用 PCIe 卡的可用内存？

系统详情：

Linux 2.6.35-28-generic i686 Ubuntu 10.10 (All updates installed)
NVIDIA Driver Version: 260.19.06 (Official)

如果需要更多信息，请告诉我。

如果我要找的东西不可行，请告诉我，这样我就可以禁用板载卡并恢复那 400MB 浪费的 RAM

谢谢你的帮助！

Answer 1

并不是真正同时...每个显卡都有一个Bios，试图控制计算机中的所有视频。只有一个会获胜...除非两个视频都设计用于共享控制（Crossfire 或 SLI），否则您不能同时运行两个视频卡...

据我所知，两者同时工作的唯一场景是 ATI 混合交火“混合图形”
