Xorg.conf 没有让我看到任何可见的输出

我还有另一台笔记本电脑，它是专有 Nvidia 驱动程序的受害者。我想在笔记本电脑（配备 Quadro M1000M 和 4k 显示屏的 Dell Precision 5510）上进行 CUDA 开发，因此我需要专有驱动程序。

我已经尝试了几个小时了，甚至通读了这，我只是不知道当 xorg 无法自动配置时如何配置它。我曾经最初nvidia-xconfig设置过xorg.conf，然后我必须BusID向该部分添加一个设置Device才能找到该卡。现在，startx运行没有错误（我可以验证事情是否确实正常工作），但它就像只显示在鬼屏上。我可以DISPLAY=:0 xrandr远程运行，并获得一个没有输出的 8x8 虚拟屏幕：

Screen 0: minimum 8 x 8, current 8 x 8, maximum 16384 x 16384

我在 xorg 日志文件中得到以下与 Nvidia 相关的输出块，其中有几个可疑的 NULL 值：

这是我目前的xorg.conf：

如果您说您以前没有xorg.conf，并且您使用该内容创建了它，那么我会从更简单的开始。你不需要这一切。

使用 nvidia 驱动程序所需要做的就是：

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
EndSection

对于 OpenGL，您可能还需要以下内容：

Section "Files"
    ModulePath "/usr/lib64/opengl/nvidia"
EndSection

（确切值取决于您的系统路径）

如果仍然不起作用，请发布整个 xorg 日志。
