Raringがwikiでサポートされているとリストされているので、この問題は解決されたと思います https://wiki.ubuntu.com/Bumblebee
Lspciを実行すると、私のGPUがリストされます
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)
誰もが実用的なソリューションを持っていますか？
だからバンブルビーを動作させるには
a）次のコマンドを実行して、NvidiaグラフィックカードのBusIDを確認します。
lspci | grep NVIDIA
BusIDは、上記のコマンドによって返される行の先頭の番号です。上記のコマンドの出力がラップトップ上でどのように見えるかを以下に示します。
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 525M] (rev ff)
BusIDは太字の数字で、私の場合は「01：00.0」です。
b）次に、BusIDを/etc/bumblebee/xorg.conf.nvidiaに追加する必要があります。このため、テキストエディターでルートとしてファイルを開きます（以下のコマンドでGeditを使用します）。
Sudo gedit /etc/bumblebee/xorg.conf.nvidia
そして、このファイルの「デバイス」セクションで、次を追加します。
BusID "PCI:YOUR_BUS_ID"
「YOUR_BUS_ID」をステップa）で使用されたコマンドによって返されたBusIDに置き換えます。私にとって（あなたにとって、BusIDは異なるかもしれません）、この行は次のようになります。
BusID "PCI:01:00:0"
次に、システムを再起動すると、Bumblebeeが動作するはずです。Nvidiaカードでアプリケーションまたはゲームを実行する場合は、次を使用します。
optirun APP_OR_GAME
optirun glxspheres

更新
/etc/bumblebee/xorg.conf.nvidiaは次のようになります
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"
