I've already tried to follow literally everything on ask ubuntu and similar websites but still I cannot manage my graphic card:

  • If I look under system settings "Graphics", Ubuntu seems unable to recognize any kind of graphic device (not even intel) since it says: "Driver Unknown"
  • Under the tab "proprietary drivers" of the software center it is listed only the Broadcom card, but not nvidia.

  • Still, if I run 

    lspci| grep VGA

    the system returns:

    00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated
Graphics Controller (rev 02)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M]
(rev a1)

    so the system knows that the graphic cards are there.

  • I've already tried (after the installation of the kernel source and headers using -$(uname -r) to avoid problems) to install the bumblebee repositories and then the nvidia drivers, but still if I run:

    optirun glxspheres

    the system returns:

    [ 3740.367448] [ERROR]Cannot access secondary GPU - error: Could not load GPU
driver
[ 3740.367550] [ERROR]Aborting because fallback start is disabled.

I'm frankly bewildered and frustrated: what can I do or check now?

  • Have you tried rebooting? – Lekensteyn Jan 13 '13 at 21:02
  • yes, that's the result: 
    [  296.503050] [ERROR]Cannot access secondary GPU - error: 
[XORG] (EE) Failed load module "nvidia" (module does not    
exit, 0)

  • Ensure that you have the headers package installed, see http://askubuntu.com/a/36936/6969. If you have also installed drivers other than nvidia-current (e.g. nvidia-current-updates), you also need to edit /etc/bumblebee/bumblebee.conf to reflect those changes. If you do not know what you are doing, just uninstall all nvidia-experimental and nvidia-current-updates packages and still to nvidia-current from ubuntu-x-swat/x-updates as described in the link. – Lekensteyn Jan 13 '13 at 21:35
  • I installed headers using:

    $(sudo apt-get install linux-headers-$(uname -r))

    how do I check if they're correctly installed?

    I also tried, as @Lekensteyn suggested to uninstall all nvidia-experimental and nvidia-current-updates and then reinstall nvidia-current (but from Bumblebee since under ubuntu-x-swat/x-updatesd it didn't found any nvidia package) using

    $(sudo apt-get install bumblebee nvidia-current)

    The situation worsened: after reboot the desktop was not showing, compiz was not working and "Graphics" still told "Drivers: Unknown"

  • You need to install both the bumblebee/stable and ubuntu-x-swat/x-updates PPAs. Remember to reinstall bumblebee-nvidia after installing nvidia-current. Something like sudo apt-get purge nvidia-current nvidia-current-updates nvidia-experimental-* bumblebee-nvidia && sudo apt-get install bumblebee-nvidia – Lekensteyn Jan 14 '13 at 20:32
  • Ok! The system settings still says "Drivers Unknown", but running optirun glxspheres now starts the GeForce graphical interface! Is there a way to manage which program to "optirun" beside launching them via terminal using optirun? Thanks everybody for your help!!!! – Mutewinter Jan 14 '13 at 22:23
