Cannot access secondary GPU

[Giorgio Dramis]

I have Ubuntu 14.04 LTS and i have installed on it bumblebee bumblebee-nvidia and nvidia-current but when i open the terminal and launch the command optirun glxgears i receive this answer

[ 471.657278] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(0): Failed to initialize the NVIDIA GPU at PCI:1:0:0. Please

[ 471.657402] [ERROR]Aborting because fallback start is disabled.

With Ubuntu 13.10 I have the same problem with drivers nvidia-319 and nvidia-331. With nvidia-current the fps is locked at 60.

Same problem with lubuntu 14.04 64Bit.
bumblebee 3.2.1-5
bumblebee-nvidia 3.2.1-5

A complete ppa purge and reinstall did not solve this problem.

$ lspci | grep -i nvid

We need the dmesg log corresponding to such unsuccessfull attempts in order to help you.
