安装xorg-x11-drv-nvidia后才出现黑屏，但ctrl+alt+f2救了我加载到终端登录屏幕；之后“startx”对我有用。
我可以在我的系统上检查什么？
这是我的xorg.log文件：

答案1
假设您除了安装软件包之外没有做任何事情，有两件事：
必须修改 xorg.conf 才能加载 nvidia 驱动程序。
Driver "nvidia"请注意，通过 xorg.conf 与任何人交谈几乎是不可能的，这就是它应该编写脚本的原因。模式设置必须在 grub 中列入黑名单，然后更新 grub。
由于某些令人费解的原因，尽管现在已经有了几十年的知识，这些分发包仍然无法自动执行这两个操作，而这两个操作是加载非免费驱动程序所需的。正如您所看到的，所有驱动程序都加载在 xorg 上，但 xorg 不知道它应该使用 nvidia，而不是模式设置。
他们也无法实际检查实际视频卡/设备的总线 ID，以确保正在安装的驱动程序是正确的驱动程序。如下，这是一个10多年前就已经完全解决的问题，根本不应该存在。但驱动程序包创建者拒绝这样做。例如，对于 nvidia，他们通常支持 3 到 4 个旧版本的卡，并且根据这些列表检查已安装的卡 ID 以确保安装正确的驱动程序基本上是微不足道的。
这就是为什么您在 Xorg.0.log 中看到模式集操作而几乎没有 nvidia 操作
我一直感到遗憾的是，这个问题仍然存在于分发驱动程序包中，绝对没有任何借口，编写这些解决方案的脚本只需要几百行代码即可为全球所有用户解决该问题。另一种非解决方案是，用户年复一年地问同样的问题，同样的问题，采用同样的解决方案，就好像支持是一种可以假设的无穷无尽的商品，而解决方案始终是为所有用户编写脚本。
[进一步注意，这些解决方案不仅可以完全脚本化，而且据我所知，它们已经完全脚本化了好几次，但分发包维护者坚决拒绝在其包装中实现这些解决方案]。
