联想 T520 上的三头

Question

• 联想 T520 集成 Intel HD 显卡 + NVidia 卡 (Optimus)
• 计算机上的 Ubuntu 11.10。
• 我想使用内置屏幕加两个外置屏幕。
• 此 PDF表明最多可以将四个外部显示器连接到笔记本电脑。该信息仅适用于 Windows。
• 我打算禁用 NVidia 卡，因为我读到 Linux 对 Optimus 的支持不好。

问题：

• 有人在 NVidia 硬件上设置了三个显示器吗？
• 有没有人使用 Intel HD 3000 设置三台显示器？
• 我可以期待它开箱即用，还是需要注意一些技巧？

Answer 1

在 BIOS 中启用 Optimus 和操作系统检测后，我有 2 个外部 DVI 连接的显示器（对接 - Nvidia 卡）和笔记本电脑 LCD（英特尔卡）可以工作。我也确实在坞站上安装了 VGA（英特尔卡），但无法将其用作笔记本电脑 LCD 的克隆。

这是我启用了 Xinerama 的 xorg 配置：

在“DeviceIntel”部分是我最后一次尝试在 Intel 卡上安装多个显示器。

这是我的“lspci”的摘录：

$ lspci |grep VGA
