Ubuntu – Ubuntu 14.04 Nvidia Optimus Bumblebee error

14.04bumblebeenvidia-optimus

I know that in Ubuntu 14.04 there exists nvidia-prime for Nvidia Optimus, but I don't like it and neither am I able to get it work. After upgrading from Ubuntu 12.04 everything crashed, and I made a clean install of Ubuntu 14.04 and Bumblebee, but now I have new troubles. After running optirun glxgears I get the following error: 

**[ 4703.996785] [ERROR]Cannot access secondary GPU, secondary X is not active.**
**[ 4703.996910] [ERROR]Aborting because fallback start is disabled.**

Please help.

I had to edit the file '/etc/bumblebee/bumblebee.conf' and set the driver manually :

Driver=nvidia

You should have a corresponding [driver-nvidia] section in your file with the current version of your nvidia driver :

[driver-nvidia]
# KernelDriver=nvidia-current
KernelDriver=nvidia-331
# LibraryPath=/usr/lib/nvidia-current:/usr/lib32/nvidia-current
LibraryPath=/usr/lib/nvidia-331:/usr/lib32/nvidia-331
# XorgModulePath=/usr/lib/nvidia-current/xorg,/usr/lib/xorg/modules
XorgModulePath=/usr/lib/nvidia-331/xorg,/usr/lib/xorg/modules

then restart the bumblebee daemon :

sudo service bumblebeed restart
