将板载VGA输出与PCIevideo卡配合使用。 两者都是nVidia

我有2个video卡，一个在板上，一个nVidia 6150SE nForce 430和一个PCIe nVidia GeForce GT 220 1GB DDR2 RAM

我已经配置PCIe卡使用双显示器function，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

我已经设法启用板载图形处理器，这需要400MB的RAM，但我无法设法使用它， nvidia-settings没有检测到它，就像它不可用（但是有）

我的问题如下：

1. 如何设置板载VGA显示器与PCIe图形卡配合使用？

2. 如果可能的话，我如何恢复板载卡上的400 MB（即使没有使用），或者我如何才能使用PCIe卡可用内存？

系统细节：

 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。

以下是禁用板载卡时的lspci输出：

这是两个都启用时：

如果我找不到的是，请告诉我，所以我可以禁用板载卡并恢复那400MB浪费的RAM

谢谢你的帮助！

Answer 1

不是真的同时…每个video卡都有一个Bios，试图控制计算机中的所有video。 只有一个会赢…除非两个video都是为共享控制（Crossfire或SLI）设计的，否则你不能同时运行两个video卡….

我所知道的唯一可以同时工作的场景是ATI混合交火“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，我很想知道你是否可以使用它的两张卡：
