我使用的是索尼 VGN-SZ32CP 笔记本电脑，它配备了 nVidia GeForce Go 7400 显卡和 128MB 内存，以及集成显卡“Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics”。在 3.0 之前一切都很好，但是自从它发布以来，这台电脑从来没有使用过 nVidia 卡，而是用英特尔的。系统似乎根本检测不到它。

如您所见，nVidia 卡不在列表中。
答案1
尝试使用以下方式检查你的 nVidia 卡
sudo lspci -H 1
或者
sudo lspci -H 2
如果这不起作用，请尝试进入睡眠模式，然后唤醒，并执行上述命令。如果您仍然看不到 nVidia 卡，那么最后一个选项是更改 BIOS 设置。如果您看到了 nVidia 卡，那么让它工作可能并不容易。使用“modprobe nvidia”加载模块对我来说不起作用，我需要尝试进行高级 PCI 资源调整。
