VMware中Ubuntu20.04下Nvidia显卡连接外屏显示教程

连个屏幕都这么费劲嘛😩😫

• 我们要用显卡坞上的视频接口HDMI或者DP来输出（显卡端口输出），因为直接通过显卡端口输出可以节省显卡与cpu的交流，

• 首先找到你的显卡PCI地址：

  lspci

• 找到这一行：

  03:00.0 VGA compatible controller: NVIDIA Corporation TU104 [GeForce RTX 2070 SUPER] (rev a1)

• 03就是地址，十六进制表示，不过03的十进制还是03。

• 创建文件夹：

  sudo mkdir /etc/X11/xorg.conf.d/

• 然后创建文件：

  sudo vim /etc/X11/xorg.conf.d/nvidia.conf

• 在文件中粘贴，保存，退出：

  Section "Device"
  		Identifier      "Videocard0"
  		BusID           "PCI:03:0:0" # 把03换成你的地址
  		Driver          "nvidia"
  		VendorName      "NVIDIA Corporation"
  		Option          "AllowEmptyInitialConfiguration"
  		Option          "AllowExternalGpus"
  EndSection

• 最后，修改10-nvidia.conf文件

  sudo vim /usr/share/X11/xorg.conf.d/10-nvidia.conf

• 原本是这样：

  # This xorg.conf.d configuration snippet configures the X server to
  # automatically load the nvidia X driver when it detects a device driven by the
  # nvidia-drm.ko kernel module.  Please note that this only works on Linux kernels
  # version 3.9 or higher with CONFIG_DRM enabled, and only if the nvidia-drm.ko
  # kernel module is loaded before the X server is started.
  
  Section "OutputClass"
     Identifier     "nvidia"
     MatchDriver    "nvidia-drm"
     Driver         "nvidia"    
  EndSection

• 加入Option "AllowExternalGpus" "true"：

  # This xorg.conf.d configuration snippet configures the X server to
  # automatically load the nvidia X driver when it detects a device driven by the
  # nvidia-drm.ko kernel module.  Please note that this only works on Linux kernels
  # version 3.9 or higher with CONFIG_DRM enabled, and only if the nvidia-drm.ko
  # kernel module is loaded before the X server is started.
  
  Section "OutputClass"
     Identifier     "nvidia"
     MatchDriver    "nvidia-drm"
     Driver         "nvidia" 
     Option "AllowExternalGpus" "true"
  EndSection

• 按esc退出，输入:wq退出；

• sudo reboot；

• 等开机画面过后，你就可以看到你的外接屏幕上有画面了。
