NVIDIA driver issues Ubuntu 16.04
I am trying to install the latest Nvidia drivers. After the install nvidia-smi can't find it.
The graphic card is a GeForce 860m, and my laptop is under Ubuntu 16.04.1 LTS.
What I did so far:
$ sudo apt-get purge nvidia-*
$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt-get update
$ sudo apt-get install nvidia-367
$ reboot
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
How can I make it work ?
EDIT:
I realized $ sudo apt-get install nvidia-367 returned the error:
Error! Bad return status for module build kernel: 4.4.0-36-generic (x86_64)
Consult /var/lib/dkms/nvidia-367/367.44/build/make.log for more information.
Although the driver is actually running.
make.log contains lines like this:
Makefile:676: Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compiler
and this:
cc: error: unrecognized command line option ‘-fstack-protector-strong’
scripts/Makefile.build:258: recipe for target '/var/lib/dkms/nvidia-367/367.44/build/nvidia/nv-instance.o' failed

Solution 1:
gcc-4.8 didn't support -fstack-protector-strong
I installed gcc-4.9 instead, purged and reinstalled the driver, and now it's working fine.
$ nvidia-smi

Ironic is that I used gcc-4.8 because IIRC a previous version of CUDA wasn't compatible with versions 4.9 or later.
