The fact that Bumblebee is unable to find a library path is odd to me, since I only recently updated bumblebee.conf like so:

## Section with nvidia driver specific options, only parsed if Driver=nvidia
# Module name to load, defaults to Driver if empty or unset
# colon-separated path to the nvidia libraries
# comma-separated path of the directory containing nvidia_drv.so and the
# default Xorg modules path

My laptop using a Gefore GT 525M. All the modules appear to be in place:

~$ find /lib/modules/$(uname -r) -name 'nvidia*.ko*'
~$ find /usr/ -name 'nvidia_drv.so'
find: `/usr/share/doc/google-chrome-stable': Permission denied

And I have just updated Bumblebee. Is there some reason I'm unable to use Bumblebee to run programs on my video card?

    new here, I was having the same problem, Bumblebee working well, then I installed a fresh ubuntu 14.04 and got the issue, this guide worked well for me muktware.com/2013/12/install-nvidia-331-bumblebee-optimus-cards/… (without the nvidia-settings) I tried broker's way but it made my gdm freeze just before the login screen (using ubuntu gnome). – Basier Apr 20 '14 at 16:07
  • Question: what's the difference between the 331 Nvidia driver in the official PPA and the one from xorg-edgers? Or is there none? Just don't want to add PPAs that might break things. – MowDownJoe Apr 21 '14 at 1:50
  • thank you very much for your workaround which finally worked for me on my hp envy dv6 laptop. But I had somehow an unknown display set as default, under gnome none of the menu bars did show up, which I could resolve by rightclicking and choose the screen background settings for being able to reach the rest of the system settings. Maybe this helps someone running into the same problems... – user272883 Apr 23 '14 at 7:07

Remove bumblebee and libvdpau-va-gl1
