I am using a dell developer edition xps 13 (9360), which has intel iris graphics. (i915 module).

When I play full screen video that changes a lot, I see a bunch of screen tearing, which creates a weird checkerboard pattern. It's extremely distracting.

I have found some suggestions to fix this including:

  • Edit /etc/X11/xorg.conf.d/20-intel.conf to include the line "Option "TearFree" "true"(according to the arch wiki).

But this file and directory path don't exist in ubuntu 16.04. I tried editing /usr/share/X11/xorg.conf.d/20-intel.conf with the following contents:

Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"
  Option "TearFree" "true"
EndSection

But it doesn't seem to have had any impact. This is directly from the arch wiki. The suggestion mentions an "intel" module but I believe the correct module for my video accelerator is "i915" isn't it? But if I switch "intel" to "i915" I get an xorg crash notice at boot time.

By default there appears to be a file called /usr/share/X11/xorg.conf.d/10-intel-modesetting.conf which has the following contents:

Section "Device"
        Identifier "Configured Video Device"
        Driver "modesetting"
EndSection

I've also tried adding the entry there, but it doesn't seem to make a difference.

  • Install zesty firmwares and kernels in xenial

Sadly this breaks virtualbox dkms which means this isn't a usable solution for me since I use it for development constantly.

I have updated the intel video modules using the updater provided by 01.org.

Does anyone have any possible solutions that I could try to get this working properly? A dist upgrade isn't really an option because it breaks most of the dell integrations that are actually extremeley useful.

  • Also seeing this on Arch Linux, but I had suspected it was due to having two monitors running off the card. How many monitors do you have connected? – Malvineous Nov 21 '18 at 5:04
