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:
如何才能使板载 VGA 显示器与 PCIe 显卡协同工作?
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。

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:
