openSUSE13.2，GT640M LE
今天折腾了一上午终于弄好了 bumblebee，经 furmark 测试有效，直接运行 FPS 不到 10，optirun FPS 能达到 20 以上，和 windows 下运行效果差不多。
但是 nvidia x server settings 打不开，
ERROR: libnvidia-gtk3.so.352.21: cannot open shared object file: No such file
or directory

ERROR: A problem occured when loading the GUI library. Please check your
installation and library path. You may need to specify this library when
calling nvidia-settings. Please run `nvidia-settings --help` for usage
information.
另外，运行 steam 可以打开，但是 optirun steam 就会报错
OpenGL GLX context is not using direct rendering, which may cause performance problems.
这要如何解决？谢谢！
