在 Ubuntu 18.04.3 中未检测到 Nvidia GTX 1650

Question

我最近买了这台机器：ASUS TUF FX505DT - AMD Ryzen 5 3550H with GTX 1650 4GB。它随 Windows 10 预安装一起提供。GTX 1650 显卡在 Windows 中运行没有任何问题。我清理了我的 SSD，在 BIOS 中禁用了安全启动并安装了 Ubuntu 18.04.3 后，无法识别显卡。

我添加了graphics-drivers/ppa，清除了所有现有的 NVIDIA 软件包，安装了nvidia-driver-430（也尝试了 435），但仍然无法正常工作。我还ppa:xorg-edgers/ppa使用以下命令进行了安装：

sudo add-apt-repository ppa:xorg-edgers/ppa

这是安装驱动程序之前附加驱动程序显示的内容：

这是安装驱动程序后附加驱动程序显示的内容：

这是关于机器的关于信息：

产品型号在附加驱动程序设置中显示为未知。产品型号只是 NVIDIA 中的lshw -C display.

安装驱动程序后，如果我重新启动并尝试登录 Ubuntu (Xorg)，它会在登录屏幕中冻结或立即注销。但是 Ubuntu (Wayland) 登录工作正常。但即使安装了所有驱动程序，Wayland 的屏幕仍会不断闪烁。

从发帖者的评论到详细的修复；

不要添加图形驱动程序 ppa，如果添加了，请删除包括 ppa 在内的所有内容。

从菜单中打开“附加驱动程序”，然后选择专有的经过测试的驱动程序并重新启动。

然后创建目录并通过以下命令将文件复制到其中：

    sudo mkdir /etc/X11/xorg.conf.d
    sudo cp /usr/share/X11/xorg.conf.d/10-nvidia.conf /etc/X11/xorg.conf.d

然后添加Option "PrimaryGPU" "Yes"到OutputClass以下文件的

sudo vim /etc/X11/xorg.conf.d/10-nvidia.conf

它最终应该看起来像这样：

Section "OutputClass"
    Option "PrimaryGPU" "Yes"    
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"
EndSection

然后重新启动。重启后，尝试nvidia-smi命令看是否有效。

我让 gtx1660ti 与这个解决方案配合得很好。
