我尝试使用此处找到的文档进行安装（https://wiki.archlinux.org/index.php/Bumblebee），但是运行时：
optirun glxgears -info
我得到这个输出：
[ 309.531594] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) Failed to load module "nouveau" (module does not exist, 0)
[ 309.531645] [ERROR]Aborting because fallback start is disabled.
我有两张显卡：一张是 Intel 集成的，一张是专用的 GeForce GTX 960M。
的输出inxi -G：
