我在配备 Nvidia GeForce MX150 的笔记本电脑上使用 Artix Linux（基于 Arch Linux）。我安装了专有的 nvidia 驱动程序。它是一个 Optimus GPU（至少它是这么认为的），我想让 X-Server 在 GPU 上运行：我切换到 Nvidia nvidia-prime-select（AUR：nvidia-prime-select-git）。之后X-Server就不再启动了。

然后我在终端会话上执行nvidia-prime-select intel，sddm 正常启动（当然是在英特尔 GPU 上）。后来我还删除了创建的/etc/X11/xorg.config nvidia-prime-ui（之前不存在）。
但现在nvidia-settings说：
ERROR: Unable to load info from any available system
在我启动它之前。
我还尝试使用 bumblebee 在 Nvidia GPU 上运行单个程序，但当我使用以下命令时，它会给出类似的错误optirun supertuxkart：

问题：
- 为什么不再
nvidia-settings起作用了？ - 当我使用 nvidia-prime-select 更改为 Nvidia GPU 时，为什么 X-Server 无法启动？
- 为什么大黄蜂不起作用？ -> 解决了
编辑：我添加BusID "PCI:1:0:0"到由 . 创建的 xorg.config 文件中的“设备”部分nvidia-prime-select nvidia。现在 xorg 启动，但 sddm 显示黑屏。新日志：https://pastebin.com/gYUv9tqN，sddm日志：https://pastebin.com/b8ixWMiJ
更新：
- 我尝试启动 Plasma 和 Gnome (Xorg)。同样的问题。
- 我添加到
BusID "PCI:1:0:0"了 nvidia 设备部分/etc/bumblebee/xorg.conf.nvidia，bumblebee 现在可以工作了！ BusID "PCI:1:0:0"我意识到，添加到时会出现不同的错误/etc/X11/xorg.conf：https://pastebin.com/JCNrA6fW
