联想 T520 上的三头
  • 联想 T520 配备集成英特尔高清显卡 + NVidia 卡 (Optimus)
  • 计算机上的是 Ubuntu 11.10。
  • 我想使用内置屏幕加两个外接屏幕。
  • 此 PDF表示最多可以将 4 个外接显示器连接到笔记本电脑。此信息仅适用于 Windows。
  • 我原本打算禁用 NVidia 卡，因为我读到 Linux 对 Optimus 的支持不佳。

问题：

  • 有人在 NVidia 硬件上设置了三台显示器吗？
  • 有人使用 Intel HD 3000 设置了三台显示器吗？
  • 我可以期望它开箱即用吗，或者我需要注意一些技巧吗？

答案1

在 BIOS 中启用 Optimus 并开启操作系统检测后，我让 2 个外部 DVI 连接的显示器（扩展坞 - Nvidia 卡）和笔记本电脑 LCD（英特尔卡）工作。扩展坞上的 VGA（英特尔卡）也工作正常，但无法将其作为笔记本电脑 LCD 的克隆。

以下是我的 xorg 配置，其中启用了 Xinerama：

在“DeviceIntel”部分是我最后一次尝试在英特尔卡上获取多个显示器。

这是我的“lspci”的摘录：

$ lspci |grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: nVidia Corporation Device 1057 (rev a1)

答案2

如果您不使用 NVidia 卡，则只能使用笔记本电脑上的单个 VGA 端口。即使您连接到扩展坞，除非您使用 NVidia 卡，否则 dvi 和显示端口都不可用。
