4. 有時 全新安裝 比抓錯 快 安全
4-1. 安裝完成後 立刻安裝 nvidia-driver-396

[devinhee]

396成功安装，重启之后，无法正常启动
4-1. sudo dpkg -l | grep nouveau
4-2. sudo dpkg -l | grep nvidia
4-3. nvidia-settings --glxinfo | grep "OpenGL version string"
以上三条命令执行结果：

1. bumblebee 是 第三方軟體 不受到 Ubuntu 自編的 Linux Kernel 支援
1-1. 對於 開源 nouveau 可能比較容易搭配 對於 閉源 nvidia 新手比較不容易安裝成功
參閱
https://github.com/Bumblebee-Project/Bumblebee/wiki/FAQ
How do I install Bumblebee?
The installation of the Bumblebee core is easy, especially with the nouveau driver. If you want to use the proprietary nvidia driver, it is going to be more difficult because certain nvidia libraries must be moved to avoid conflicts with the Mesa libraries for 3D acceleration.
1-1-1. 對於新手建議 如果要體驗 bumblebee 最好使用 開源 nouveau
https://github.com/Bumblebee-Project/Bumblebee/wiki

2. 雙顯卡
Ubuntu 自 14.04 開始 使用自編的 Linux Kernel 支援雙顯卡
但是 nvidia 必須使用 閉源 nvidia
2-1. 如果要使用 閉源 nvidia 最好徹底把 bumblebee 移除 以免衝突
2-1-1. https://wiki.ubuntu.com/X/Config/HybridGraphics
2-2, 雙顯卡 支援驅動與程式 仍然繼續發展中 每個版本 都有進展 網路上的參考文章 最好 注意一下 適用版本

3. 閉源 nvidia 還沒成功載入

困扰已久的问题现在已经解决啦！
官方推荐:nvvidia-415
卸载已经安装所有nvidia
从新安装推荐的nvidia415

代码： 全选

nvidia-smi

出现错误：NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver ...
我电脑需要从新选择

代码： 全选

prime-select query

显示为：nvidia

代码： 全选

prime-select intel
prime-select nvidia
nvidia-smi

显示成功。（过程可能需要重启）
好几次prime-select query，显示为nvidia，于是没有作切换，就一直找不到原因。安装完成有如果已经选择nvidia，建议先切换到intel，再切换回nvidia试试。

在此，再次感谢 poloshiao 君的耐心指导！
