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:


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?


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

  • I have tried both of those and can't get scrolling or my terminal to stop lagging. Is your intel card recognised? – pandaadb Aug 10 '16 at 8:43
  • I tried your approach and the 367 is not solving my issues. I seem to not be able to get the intel driver to work properly. Nvidia says it is syncing to "unknown". The terminal is still laggy when typing and scrolling in the browser causes tearing – pandaadb Aug 10 '16 at 10:22

  • Does it show that the VGA card has a driver in use? I am wondering if maybe the intel driver is configured wrong and that breaks the syncing? I can't get my system to use the intel driver (i think) – pandaadb Aug 10 '16 at 10:38
  • use the modesetting driver for the intel card – Amias Aug 10 '16 at 10:54
