Ubuntu – Ubuntu 12.10 Nvidia GT555M Bumblebee

12.10bumblebeenvidia

I have laptop with Nvidia GT 555M video card.
System Ubuntu 12.10, kernel Linux 3.5.0-17-generic

  1. step what i do:

    sudo add-apt-repository ppa:bumblebee/stable 
    sudo add-apt-repository ppa:ubuntu-x-swat/x-updates 
    sudo apt-get update 
    sudo apt-get install bumblebee bumblebee-nvidia 
    

    restart system

    optirun glxgears
    

    This message give me:
    Cannot access secondary GPU – error: Could not load GPU driver
    Aborting because fallback start is disabled.

  2. Open sudo gedit /etc/bumblebee/bumblebee.conf and change Driver= to Driver=nvidia and KernelDriver=nvidia-current to KernelDriver=nvidia. Restart the system and run optirun glxgears.

    This message gives me:

     The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect.
     Could not connect to bumblebee daemon - is it running?
    

Anybody have idea?!

  • KernelDriver=nvidia-current is correct if you have installed the nvidia-current package, you should not change that on Ubuntu. Since Ubuntu 12.10, you need to install the kernel headers yourself.

    So, revert your KernelDriver change (the Driver= one does not matter) and install the kernel headers:

    sudo apt-get install linux-headers-generic
    

    This should automatically build the nvidia module. When this is completed, reboot or start the Bumblebee daemon:

    sudo start bumblebeed
    

    Then try running optirun glxspheres again.
