联想T520上的三头

• 联想T520集成英特尔高清显卡+ NVidia显卡（Optimus）
• Ubuntu 11.10在电脑上。
• 我想使用内置屏幕和两个外部屏幕。
• 此PDF表示最多可以将四台外接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，因为我已经读过对Optimus的Linux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，还是我需要注意的技巧？

Answer 1

通过在BIOS中启用Optimus和OS检测，我有2个外部DVI连接显示器（对接 – Nvidia卡）和笔记本电脑LCD（Intel卡）工作。 我也确实在对接工作中获得了VGA（英特尔卡），但却无法将其作为笔记本电脑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 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) 

Answer 2

如果您不使用NVidia卡，您将只能使用笔记本电脑上的单个VGA端口。 即使您同时连接到扩展坞，除非您使用NVidia卡，否则将无法使用dvi和显示端口。
