我最近尝试在 lubuntu 13.10 下使用我的笔记本电脑（MSI GE60，配备 GeForce GT 750M）。从我收集的信息来看，如果我想使用 GeForce，就必须使用 Bumblebee。
我使用找到的说明安装了它这里和这里。我已将驱动程序更新至nvidia-319-updates。
但尽管如此，当我尝试运行时primusrun glxgears，我得到以下输出：

我尝试查看/var/log/Xorg.8.log，但没有找到任何有用的信息（我尝试查找错误，但得到以下结果：

我还尝试将其更改KeepUnusedXServer为true以查看是否有其他输出，但 syslog 中只有以下内容：glxgears[2086]: segfault at 0 ip 00007f5ee5d41547 sp 00007fff71783f40 error 4 in libGL.so.1[7f5ee5d1c000+41000]。
另外需要注意的是，运行时primusrun nvidia-settings出现一条消息，提示我没有运行 nvidia 驱动程序。但optirun nvidia-settings -c :8确实显示了设置。不过，它仍然会产生相同类型的登录syslog。
为了以防万一，（未注释）bumblebee.conf：

提前感谢您的回复！

嗯，它突然开始工作了。除了更新和升级之外，我没有做任何特别的事情。不知道是什么修复了它。
