Ubuntu 12.10 Nvidia GT555M Bumblebee

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.
