如何将 nvidia-xconfig 与 2 个 GPU 一起使用，而其中一个不是 NVidia？

Question

我有一组在 Ubuntu 10.04 LTS 上运行的机器，它们配备了两个图形卡，一个 NVidia GeForce GT 240（次要）和一个 Matrox 一个（主要）。因为它似乎只是忽略了 Matrox 显卡，nvidia-xconfig认为没有必要BusID在我的/etc/X11/XF86Config文件中添加字段，我需要手动添加它。鉴于 BusID 字段从机器到机器变化，我很高兴能nvidia-xconfig自动完成这项工作。

nvidia-xconfig在这种特殊情况下，是否可以强制指定正确的 BusID？请注意，使用该选项--enable-all-gpus不起作用！

Answer 1

我想出的修复方法是用来nvidia-xconfig --query-gpu-info获取 BusID，然后再次将其提供给nvidia-xconfig更新 XF86Config 文件。这是执行此操作的脚本行：

nvidia-xconfig --connected-monitor="CRT" --busid=`nvidia-xconfig --query-gpu-info | grep BusID | sed 's/PCI BusID : PCI:/PCI:/'`

最后，我的XF86Config文件如下所示：
