我有一台装有 Windows 7、Mint 13(带 XFCE)和 Ubuntu 12 的三重启动计算机。只有在 Windows 7 下,连接到第二个显卡的第二个屏幕才会出现。在 Mint 和 Ubuntu 下,第二个屏幕都是空白的,并且在我的显示属性下我只在屏幕上看到(第二个屏幕进入省电模式,因为它没有接收到信号)。
它们都显示在下面lshw
(以及我主板上的板载 GPU,但我不想使用它)。
我是否需要在 Mint 或 Ubuntu 中专门“调整”某些内容才能启用第二个 GPU?

答案1
如果两个显示器# nvidia-xconfig -a
以 root 身份使用 nvidia 卡,则会:
-a, --enable-all-gpus
Configure an X screen on every GPU in the system.
nvidia-xconfig 手册页。
编辑:假设您使用的是 nvidia 的驱动程序而不是 nouveau。
