难道没什么问题吗？

答案1

我做到了，老兄！

删除 Bumblebee 即可

sudo apt-get purge bumblebee*

然后对 Nvidia-Prime 说“你好！”

sudo apt-get install nvidia-prime

从 nvidia-settings 中选择显卡后（intel 或 nvidia）

你应该退出然后回来。（不幸的是，每次更改后都会这样）

新的 glxspheres64 输出；

./glxspheres64

Polygons in scene: 62464 (61 spheres * 1024 polys/spheres)

最终取得了好成绩:)
