相当不言自明的问题。optirun和 和有primusrun什么区别？我primusrun今天偶然发现- 通常我只是使用optirun.
注意：这可能有用：https : //applicative-games.cppcabrera.com/posts/hybrid-gfx-ubuntu.html
当我尝试使用 运行 Dota 2 时primusrun，它给了我这个错误，
ERROR: ld.so: object '/home/aleks/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

它仅在我使用primusrunwith时发生steam。
我想用 bumblebee 运行我的 Steam 但遇到了一个问题：当我尝试使用 primusrun 运行 Steam 时，我遇到了段错误。其他任何东西也不能与 primus 一起运行。这是primusrun glxspheres64使用LIBGL_DEBUG=verbose.

我正在使用 Minecraft 客户端对其进行测试，该客户端实际上已启动，但片刻后崩溃。
$ primusrun java -jar Minecraft.jar
# some normal output...
primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) No devices detected.
我可以很好地看到卡片：
$ lspci | grep 3D
01:00.0 3D controller: NVIDIA Corporation GK107M [GeForce GT 750M] (rev a1)
这个设置在同一台机器上的 Arch 下运行良好。不确定什么配置不正确。
编辑：
$ lspci -nnk | grep -iA2 VGA

Kernel driver …我最近升级到 15.04，成功安装后我注意到 Bumblebee 已停止工作。Optirun/primus 命令不再检测 gpu (640M LE)。这是我在尝试运行 Steam 时得到的：
$ primusrun steam

我的司机nvidia-346-updates。
配置文件是默认的。我应该更改内核驱动程序和库路径吗？（现在他们是nvidia-current）。
