primusrun <any application>或然后退出后optirun <any application>，独立 nVidia 显卡仍在运行。
optirun --status所有内容关闭后打印：
Bumblebee status: Ready (3.2.1). X inactive. Discrete video card is on.
这种行为有什么特殊原因吗？
安装的软件包包括bumblebee lib32-virtualgl lib32-nvidia-utils lib32-mesa-libgl mesa-demos bbswitch primus lib32-primus
我的发行版是 Arch（显卡：Intel HD 4000/nVidia GT 750M）。

提前致谢！ ：）
PS：我考虑过这个帖子：bbswitch 无法关闭独立显卡 对我的情况来说，添加 .conf 文件有帮助吗？
