Ubuntu 14.04 doesn't detect my discrete GPU
- by user258887
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?
