我正在进行一个干净的最小 Debian Stretch 安装，只安装了几个图形包。我告诉了这些：
sudo apt install xserver-xorg-core xinit bumblebee-nvidia primus primus-libs:i386 libgl1-nvidia-glx:i386
bumblebee-nvidia但我可以用开源交换专有的bumblebee。
我还将我的用户加入了 bumblebee 组：
sudo adduser $USER bumblebee
重新启动后，我的英特尔卡工作正常：
ziga@ziga-laptop:~$ glxinfo | grep OpenGL
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile
OpenGL core profile version string: 3.3 (Core Profile) Mesa 13.0.6
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 13.0.6
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 13.0.6
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00
OpenGL ES profile extensions:
但是我的 Nvidia 卡是Geforce 610M在调用时不起作用optirun：
ziga@ziga-laptop:~$ optirun glxinfo | grep OpenGL
primus: fatal: failed to load any of the libraries: /usr/lib/x86_64-linux-gnu/nvidia/libGL.so.1:/usr/lib/i386-linux-gnu/nvidia/libGL.so.1:/usr/lib/nvidia/libGL.so.1

/usr/lib/i386-linux-gnu/nvidia/libGL.so.1: wrong ELF class: ELFCLASS32

如果我apt用来搜索我的卡，我会得到：
ziga@ziga-laptop:~$ sudo apt search 610M

从这里我会安装nvidia-legacy-304xx-driver，但我担心这不适用于我上面安装的其他软件包。有没有可能我也需要xserver-xorg-video-nvidia-legacy-304xx？
谁能向我解释要安装哪些软件包以及为什么？
好吧，我等不及了，我尝试安装xserver-xorg-video-nvidia-legacy-304xx. 看起来这个包确实与bumblebee-nvidia包冲突。安装后我得到了这个：
nvidia-legacy-304xx:

我卸载了xserver-xorg-video-nvidia-legacy-304xx并尝试安装nvidia-legacy-304xx-driver也安装了该软件包的xserver-xorg-video-nvidia-legacy-304xx软件包。它没有返回任何警告也没有错误，但是重启optirun glxinfo | grep OpenGL命令后仍然失败......
看起来即使在应该是稳定的 Debian 上也没有解决方案？
就像@Antonio Orizondo Leyva 建议的那样，我安装了他建议的软件包并执行了命令sudo update-alternatives --config glx，我必须为我的 GPU 选择不同的选项：
There are 3 choices for the alternative glx (providing /usr/lib/glx).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/nvidia/bumblebee 125 auto mode
1 /usr/lib/mesa-diverted 5 manual mode
2 /usr/lib/nvidia 100 manual mode
* 3 /usr/lib/nvidia/bumblebee 125 manual mode
Press <enter> to keep the current choice[*], or type selection number:
我尝试选择其中的每一个然后重新启动，但最终结果是相同的......除了第二个选项（nvidia）在重新启动后说它找不到openGL.1.so或什么......所以甚至无法使用Nvidia卡本身！？
还有其他想法吗？
