有关我的案例的更多信息：
我这里有配备 nVidia GeForece 960M GTX 和 Debian Jessie 的 Lenovo y50-70 笔记本电脑。我正在尝试让大黄蜂工作但没有成功。我有来自实验分支的最新 nvidia 驱动程序包 (352.21)，支持我的卡。我花了几个小时并尝试了许多不同的解决方案，但我仍然遇到同样的问题。运行时optirun ....我得到以下输出：
mazikwyry@debian:~$ optirun -vv glxgears

奇怪的是，在那之后，当我跑步时，cat /proc/acpi/bbswitch我得到：
0000:01:00.0 ON
该卡似乎已启用并且无法禁用它。 sudotee /proc/acpi/bbswitch <<<OFF不生效。

Debian Jessie Stable 的 Bumblebee 不适用于 960M (*1)
http://forums.debian.net/viewtopic.php?t=125046#p603640
改用 jessie-backports 驱动程序。
如果还没有，请将以下内容添加到/etc/apt/sources.list
# jessie-backports
deb http://httpredir.debian.org/debian jessie-backports main contrib non-free
然后运行
sudo apt-get update &&
sudo apt-get purge nvidia* bumblebee* &&
sudo apt-get autoremove &&
sudo apt-get install -t jessie-backports bumblebee-nvidia
并重新启动
笔记：可能不需要执行该apt-get autoremove步骤等...并且
您可能必须执行以下操作中的一些操作https://wiki.debian.org/Bumblebee以及。
