使用车载VGA输出与PCIe视频卡。两种nVidia

Question

我有两个视频卡，一个在船上，一个nVidia 6150SE nForce 430和一个PCIe nVidia GeForce GT 220 1GB DDR2 RAM。

我已经将PCIe卡配置为使用双监视器功能，使用VGA和HDMI端口，但现在我想添加第三个监视器，使用车载VGA端口。

我已经成功地启用了车载图形处理器，它占用了400‘s的内存，但是我无法使用它，nvidia-settings没有检测到它，就像它无法使用一样(但它在那里)

我的问题如下：

1. 如何使车载VGA显示与PCIe显卡协同工作？
2. 如果可能的话，我如何恢复板卡所占用的400 MB (即使没有被使用)，或者如何让它使用PCIe卡可用的内存？

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)

如果需要更多的信息，请告诉我。

以下是禁用板卡时的lspci输出：

如果我要找的东西是不可能的，请告诉我，这样我就可以禁用板卡，恢复400 me的浪费内存。

谢谢你的帮忙!

Answer 1

不是同时..。每张视频卡都有一个Bios，试图控制计算机中的所有视频。只有一个人会赢。除非两个视频都是为共享控制而设计的(“交叉火力”或“SLI”)，否则不能同时运行两个视频卡。

我所知道的唯一两种同时工作的场景是ATI混合交叉火力“混合图形”。

Answer 2

混合图形最近有所改善。看看这个网站的各种方法，包括大黄蜂，我想看看你是否能让这两张卡片与它一起工作：
