如何从两个独立的 GPU 运行两个屏幕？

  • 772

我有两个 nVidia GTS 450 GPU，每个都有一个 DVI、一个 HDMI 和一个 VGA 端口。我想要两个屏幕，都从 DVI 端口运行。

我已经设置了我的xorg.conf文件，/etc/X11/xorg.conf但它不起作用。

xorg.conf

看起来 nVidia 忽略了我的 xorg 文件 - 当我打开 X 服务器设置程序时，我看到以下内容：

基础马赛克自动关闭，第二个屏幕被禁用。

我正在运行 Ubuntu GNOME 16.04 并安装了 nVidia 驱动程序，版本为361-updates.

如何让 nVidia 识别我的xorg.conf文件，并在两张卡上拥有两个屏幕？

    所以呃......这有点尴尬......我呃我的嗯。好的。我会说的。我的 SLI 线解开了。

    我现在已经开始工作了。虽然我还必须将我的 xorg 文件从使用 DPF-0 屏幕更改为 DVI-I-0。

    是的。
