我安装了debian，桌面环境为KDE，卸载nvidia-driver后出现以下情况。没有 xorg.conf 文件，因此我运行sudo X -configure为我的 Intel 驱动程序重新生成该文件。但我收到以下错误：

nouveauDebian 9.x 中的 X11 驱动程序版本太旧，无法支持您的 NVidia dGPU 型号。如果您的硬件配置允许（即 iGPU 物理连接到您需要的显示器/连接器；对于多 GPU Optimus 笔记本电脑，情况可能并不总是如此），您可能只能继续使用 Intel iGPU。
在大多数情况下，xorg.conf现代版本的 Xorg 不再需要完整的文件。您可能会编写一个小型配置文件，例如/etc/X11/xorg.conf.d/intel-only.conf：
Section "ServerLayout"
Identifier "Layout0"
Option "AutoAddGPU" "false"
Screen 0 "IntelScreen"
EndSection
Section "Device"
Identifier "IntelDevice"
BusID "PCI:0:2:0"
Driver "intel" # or maybe "modesetting"?
EndSection
Section "Screen"
Identifier "IntelScreen"
Device "IntelDevice"
EndSection
这将限制 X 服务器仅使用 Intel iGPU，暂时忽略 Nvidia dGPU，并自动检测所有输入设备、显示分辨率等。
