我认为这个问题可能已经解决了，因为 raring 现在在 wiki 中被列为受支持https://wiki.ubuntu.com/Bumblebee
运行 lspci 时列出了我的 gpu
lspci |grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF106M [GeForce GT 555M] (rev a1)
有人有可行的解决方案吗？
答案1
为了让 Bumblebee 工作
a) 运行以下命令来找出您的 Nvidia 显卡的 BusID：
lspci | grep NVIDIA
BusID 是上述命令返回的行首的数字。以下是上述命令在我的笔记本电脑上的输出：
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 525M] (rev ff)
BusID 是粗体数字，在我的情况下是“01:00.0”。
b) 现在我们必须将 BusID 添加到 /etc/bumblebee/xorg.conf.nvidia，为此，我们将使用文本编辑器以 root 身份打开该文件（我将在下面的命令中使用 Gedit）：
sudo gedit /etc/bumblebee/xorg.conf.nvidia
在此文件的“设备”部分中，添加以下内容：
BusID "PCI:YOUR_BUS_ID"
将“YOUR_BUS_ID”替换为步骤 a) 中使用的命令返回的 BusID。对我来说（请记住，对于您来说，BusID 可能不同），此行如下所示：
BusID "PCI:01:00:0"
然后，重新启动系统，Bumblebee 就可以正常工作了，因此，当您想要在 Nvidia 卡上运行应用程序或游戏时，请使用：
optirun APP_OR_GAME
optirun glxspheres

所以你的 /etc/bumblebee/xorg.conf.nvidia 看起来像这样
cat /etc/bumblebee/xorg.conf.nvidia
Section "ServerLayout"
Identifier "Layout0"
Option "AutoAddDevices" "false"
EndSection
Section "Device"
Identifier "Device1"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BusID "PCI:01:00:0"
# If the X server does not automatically detect your VGA device,
# you can manually set it here.
# To get the BusID prop, run `lspci | grep VGA` and input the data
# as you see in the commented example.
# This Setting may be needed in some platforms with more than one
# nvidia card, which may confuse the proprietary driver (e.g.,
# trying to take ownership of the wrong device).
# BusID "PCI:02:00:0"
# Setting ProbeAllGpus to false prevents the new proprietary driver
# instance spawned to try to control the integrated graphics card,
# which is already being managed outside bumblebee.
# This option doesn't hurt and it is required on platforms running
# more than one nvidia graphics card with the proprietary driver.
# (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT).
# If this option is not set, the new Xorg may blacken the screen and
# render it unusable (unless you have some way to run killall Xorg).
Option "ProbeAllGpus" "false"
Option "NoLogo" "true"
Option "UseEDID" "false"
Option "UseDisplayDevice" "none"
Option "ConnectedMonitor" "DFP"
