I have been working my way out of installing nvidia drivers for my ubuntu 16.04 for a long time but am not able to complete it somehow. I’ve searched almost the entire web but with no affirmation on correct process whatsoever so raising here is my last resort.
I’ve installed Nvidia 367 through .run file from the official driver page by following these instructions
https://github.com/BVLC/caffe/wiki/Install-Caffe-on-EC2-from-scratch-(Ubuntu,-CUDA-7,-cuDNN-3). But after everything is complete i’m unable to run nvidia-settings on my system as this shows me the error:
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run nvidia-xconfig as root), and restart the X server
I tried the above mentioned process but nothing happened. On my console it shows
nvidia-settings could not find the registry key file. This file should
have been installed along with this driver at
application profiles will continue to work, but values cannot be
prepopulated or validated, and will not be listed in the help text.
Please see the README for possible values and descriptions.
I can go on about telling all the procedures i’ve been trying on the web for 4-5 days where nothing seems to happen. How can i just make this nvidia-settings work/run? I’ve also tried understanding the code which is showing this error (on github, nvidia-settings repo) if it could resolve anything out but ofc nothing helped.
Is it because optimus is still not totally supported by nvidia for linux and i need to use a third party software (bumblebee) to resolve this (my card has optimus support)? Is running prime-select nvidia going to help in any way?
Also i don’t want to install Nvidia through package manager as i’ll need CUDA 8 installation later again through .run file so want to keep things consistent.
So how can i make this nvidia-settings finally work on my system (after installing through .run file as people seem to be able to run it through nvidia-367 package installation (i.e it runs fine if installed through apt-get). Is there anything i’m missing for this?)

i can provide more information xorg.conf etc if needed. This will likely help others as well in resolving this problem (or tell me if there’s any better place i can resolve this perhaps a mailing list etc). But just please help me in this.
Here are the asked logs attached.
Also i can see “is nvidia enabled:no” in gpu-manager.log. Is it the cause? Thanks.
