我刚买了一台新的 Dell XPS 14 Ultrabook，它配备了 NVIDIA GeForce GT 630M。因此，根据我在网上文档中找到的一些提示，我添加了 bumblebee ppa 并安装了 bumblebee 和 nvidia-bumblebee。
但是当我尝试使用 nvidia 卡运行某些程序时出现了这个错误：
optirun -vv firefox
[ 476.380739] [DEBUG]Reading file: /etc/bumblebee/bumblebee.conf
[ 476.381430] [INFO]Configured driver: nvidia
[ 476.381498] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect.
[ 476.381513] [DEBUG]Socket closed.
[ 476.381534] [ERROR]Could not connect to bumblebee daemon - is it running?
以下是一些配置文件：

# to take effect.

还有一些附加信息
dpkg -l | grep nvidia
ii bumblebee-nvidia 3.0.1-3~quantalppa1 amd64 nVidia Optimus support using the proprietary NVIDIA driver
ii nvidia-current 304.51.really.304.43-0ubuntu1 amd64 NVIDIA binary Xorg driver, kernel module and VDPAU library

ii nvidia-settings 304.51-0ubuntu2 amd64 Tool for configuring the NVIDIA graphics driver
我删除了 nvidia-current-updates，因为安装后 Unity 无法启动。
顺便说一句，我正在使用最新版本的 64 位 ubuntu (12.10)；并且我已经尝试重新安装 bumblebee 三次。
您能帮我修复这个错误吗？您是否需要其他信息来帮助我？
提前致谢。
