Ubuntu 18.04.3 中未检测到 Nvidia GTX 1650

我最近买了这台机器：华硕 TUF FX505DT - AMD Ryzen 5 3550H 搭配 GTX 1650 4GB。它预装了 Windows 10。GTX 1650 显卡在 Windows 中运行正常。在我清理 SSD、在 BIOS 中禁用安全启动并安装 Ubuntu 18.04.3 后，显卡无法识别。

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），但仍然不起作用。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：

安装驱动程序后，附加驱动程序显示的内容如下：

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

从发帖人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。

打开附加驱动程序从菜单中选择专有测试的驱动程序并重新启动。

然后通过以下命令创建目录并将文件复制到其中：

    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

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

最后看起来应该是这样的：

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

然后重启。重启后，尝试nvidia-smi命令看看是否有效。

我让 gtx1660ti 与该解决方案配合良好。
