Graphics issue with intel and nvidia

Question

I just did a fresh install of Ubuntu 16.04 for my intel/nvidia combo because I could not get rid of waves/slight tearing when scrolling in chrome.

I was convinced that my nvidia chip is the issue here, but I am not sure anymore. I have created a thread for my issue here:

https://ubuntuforums.org/showthread.php?t=2327162&p=13500945#post13500945

And the one difference that I can see between a user that manages to get graphics working properly and my setup is that it seems my intel card is configured wrong.

Here is my output:

artur@pandaadb:~$ lspci -knn | grep -EA2 'VGA|3D'
00:02.0 VGA compatible controller [0300]: Intel Corporation Skylake Integrated Graphics [8086:191b] (rev 06)

    Subsystem: Dell GM107GLM [Quadro M1000M] [1028:06e5]
    Kernel driver in use: nvidia

I wonder if my issue is that the intel card is not using any kernel driver, since with other users the output usually says:

Kernel driver in use: i915

After my install, i am now using the nvidia 361 proprietary driver.

So the question I guess is, do i need to have the i915 driver installed? Is it already installed? How do i get my system to use this driver?

In my additional drivers settings, the intel card is also set to "unknown".

From googling I found that 16.04 has the latest intel drivers already, which is why there is no installer. I am not sure however how to get my system to actually use those drivers.

Currently I also have the device disabled (in additional drivers), to see if that would fix my issue.

EDIT: Might this be unfixable and have something to do with the vsync issue for laptops?

Answer 1

i have a dell precision m3800 which has a similar setup , it works fine with the drivers from https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa

i have found that nvidia-358 and nvidia-367 seem to work best with my quadro K1000M , i don't get any tearing on its built it 4k screen or my external one.

Heres my xorg.conf for running with full nvidia acceleration as generated by nvidia-settings
