我需要你的帮助，因为我已经查阅了整个文档和日志，试图找出发生了什么。我使用的是 ThinkPad X1 Extreme Gen 2 笔记本电脑，配有两个外置 ThinkVision 显示器。为了让显示器渲染某些内容，我必须安装 NVIDIA，这是我的配置：
export __NV_PRIME_RENDER_OFFLOAD=1
export __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0
export __GLX_VENDOR_LIBRARY_NAME=nvidia
export __VK_LAYER_NV_optimus=NVIDIA_only
OpenGL 和 Prime with offload 已启用。我的 Intel 和 NVIDIA 总线 ID 设置正确。外接显示器工作正常，但当我拔下它们时，一切都冻结了。日志没有journalctl说明太多：

当我拔下并插入显示器时，日志会被记录下来。即使没有外接显示器，GDM 也能正常工作。
任何帮助都将不胜感激。
答案1
我今天也遇到了同样的问题
我生成了xorg.conf但是nvidia-xconfig在此之前，我从前一个文件中进行了备份。
新版本（目前使用 515.57-1）生成的 xorg.confnvidia-utils没有添加那个额外的部分。
Section "Device"
Identifier "Device1"
Driver "modesetting"
VendorName "Unknown"
EndSection
在本ServerLayout节中，有一个新行Inactive "Device1"
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0"
Inactive "Device1"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
EndSection
也许这不是最好的/正确的解决方案，但它对我有用，它是由旧版本的nvidia-xconfig
