我希望用 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，出现了段错误。其他任何东西也无法用 primus 运行。以下是使用 运行的primusrun glxspheres64示例LIBGL_DEBUG=verbose。

如果我使用 运行 steam optirun，steam 本身可以正常工作，但在启动 Dota 时，它会给我一些其他错误。启动选项：
LD_PRELOAD=libpthread.so.0 libGL.so.1 __GL_THREADED_OPTIMIZATIONS=1 optirun %command%
记录本身：
Game update: AppID 570 "Dota 2", ProcID 10988, IP 0.0.0.0:0
ERROR: ld.so: object '/home/shy/.steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.
/bin/sh: 1: libGL.so.1: not found
Game removed: AppID 570 "Dota 2", ProcID 10988
我尝试手动从我的/usr/lib32/nvidia-343to复制 libGL.so.1~/steamlibs并使用它。现在 Dota 给我一个段错误。
Game update: AppID 570 "Dota 2", ProcID 12567, IP 0.0.0.0:0

我究竟做错了什么？
