I recently purchased a laptop with an Nvidia GeForce 860m, and have installed Ubuntu 14.04. On my old laptop I had 12.04, which automatically filled Additional Drivers with Nvidia drivers. But on this computer, the only thing in Additional Drivers is Qualcomm. So I manually installed Nvidia, but X Server Settings doesn't seem to detect any GPU...

lspci | grep VGA reports only my integrated Intel GPU, but

lspci -v reports many things, including the Nvidia GPU:

01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 860M] (rev a2)
Subsystem: ASUSTeK Computer Inc. Device 157d
Flags: fast devsel, IRQ 16
Memory at ec000000 (32-bit, non-prefetchable) [size=16M]
Memory at c0000000 (64-bit, prefetchable) [size=256M]
Memory at d0000000 (64-bit, prefetchable) [size=32M]
I/O ports at e000 [size=128]
Expansion ROM at ed000000 [disabled] [size=512K]
Capabilities: access denied

Don't know what any of that means. Not sure if it's supposed to say 'access denied'...

I need my GPU to do CUDA and OpenGL programming. What else can I do to figure out why this isn't working?

EDIT: per request, the contents of xorg.conf :

It was fixed by installing nVidia driver version 331:

sudo apt-get purge nvidia*
sudo apt-get install nvidia-331-updates-dev

Then installing bumblebee per the instructions here:

sudo apt-get install bumblebee bumblebee-nvidia primus

After a reboot, I was able to use my nVidia gpu for specific programs by using the 'optirun' command. :)
