I have a laptop with hybrid graphics, and I can't get my nvidia card to work with the proprietary drivers.

nvidia drivers installed:

sudo dpkg -l | grep nvidia
ii  nvidia-361                                      367.57-0ubuntu3                               amd64        Transitional package for nvidia-367
ii  nvidia-367                                      367.57-0ubuntu3                               amd64        NVIDIA binary driver - version 367.57
ii  nvidia-opencl-icd-367                           367.57-0ubuntu3                               amd64        NVIDIA OpenCL ICD
ii  nvidia-prime                                    0.8.4                                         amd64        Tools to enable NVIDIA's Prime
ii  nvidia-settings                                 367.35-0ubuntu1                               amd64        Tool for configuring the NVIDIA graphics driver

Xorg errors:

I also noticed that I get issues with nvidia-persistenced on boot:

[FAILED] Failed to start NVIDIA Persistence Daemon.
See 'systemctl status nvidia-persistenced.service' for details.

systemctl status nvidia-persistenced doesn't give me more information, but I noticed that in journalctl -xl I get the following line at some point:

nvidia-persistenced.service: Failed at step EXEC spawning /usr/bin/nvidia-persistenced: No such file or directory

Oh and also, I guess the output of lsmod could be useful here:

lsmod | grep nvidia
nvidia_drm             16384  0
nvidia_modeset        765952  1 nvidia_drm
nvidia              11489280  1 nvidia_modeset
drm                   368640  12 i915,nvidia_drm,drm_kms_helper

I am running ubuntu 16.10

Linux cerberus 4.8.0-28-generic #30-Ubuntu SMP Fri Nov 11 14:03:52 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I had the same problems on 16.04. With a default install, my machine doesn't work. I got cpu soft lockups all the time, by simply running the lspci command. In order to solve the cpu freezes, I had to install nvidia's proprietary drivers and blacklist nouveau. (even though in the end, the proprietary drivers aren't loaded).

I have really no idea what seems to be the problem here... I really hope you can help me, in fact, I have this machine for almost a year now, and made multiple attempts to solve this issue, unsuccessfully... but didn't have time to dig deeper into this problem. I really need to do some cuda programming, so it starts to be urgent, hence this post =)

Looking forward to your answer!

Have you tried Bumblebee? It's gonna to take a long time before nvidia releases any driver with Optimus support on linux plataforms. As we wait it's recommended to use Bumblebee.
