使用板载 VGA 输出和 PCIe 显卡。nVidia

我有 2 个显卡，一个是板载的，一个nVidia 6150SE nForce 430是 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台显示器，使用板载 VGA 端口

我已经设法启用了板载图形处理器，它占用了 400MB 的内存，但我无法使用它，nvidia-settings没有检测到它，就像它不可用（但确实存在）

我的问题如下：

  1. 如何才能使板载 VGA 显示器与 PCIe 显卡协同工作？

  2. 如果可能的话，我该如何恢复板载卡占用的 400 MB（即使没有使用）或者如何让它使用 PCIe 卡可用内存？

系统详细信息：

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。

以下是lspci板载卡禁用时的输出：

如果我无法找到所需内容，请告诉我，以便我可以禁用板载卡并恢复浪费的 400MB RAM

感谢您的帮助！

答案1

并非同时运行……每张显卡都有一个 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为共享控制（Crossfire 或 SLI），否则您无法同时运行两个显卡……

据我所知，唯一可以同时工作的情况是 ATI 混合交火“混合显卡”

答案2

混合图形最近有所改进。看看这个网站上的各种方法，包括大黄蜂，我很想知道你是否可以让这两张卡一起工作：
