• When running optirun glxgears, I get:

    [ 1211.541206] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver
    [ 1211.541351] [ERROR]Aborting because fallback start is disabled.
  • When running lspci -k | grep VGA, only the internal GPU shows up:

    00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)
  • The secondary GPU only appears as a 3D controller when running lspci -k | grep 3D

    03:00.0 3D controller: NVIDIA Corporation Device 1341 (rev a2)
  • [as requested by comments]

    dpkg --get-selections | grep nvidia:

    bumblebee-nvidia                install
    nvidia-304                  install
    nvidia-current                  install
    nvidia-settings                 install
  • Contents of /etc/bumblebee/bumblebee.conf

  • What is the output of dpkg --get-selections | grep nvidia? Also can you post the contents of /etc/bumblebee/bumblebee.conf? (you can use paste.ubuntu.com) – Salem Mar 26 '15 at 22:33
