I have a bad screen tearing issue with 18.04. Config posted below. I'm not sure how to fix this issue as I've googled it several times and there doesn't seem to be much information relating to 18.04 on this issue. Thanks in advance for your answers.

Do

sudo mkdir -p /etc/X11/xorg.conf.d/
sudo vim /etc/X11/xorg.conf.d/20-intel.conf

Then paste this to the file

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

Reboot

  • Maybe worth noting that this source for this tip says that this option "may increase memory allocation considerably and reduce performance". I've certainly experienced that. Much worse than the screen tearing. – LondonRob Sep 17 at 16:31

If your laptop is quite new (I have Broadwell i7 for example) you can remove the Intel driver:

sudo apt purge xserver-xorg-video-intel

as the actual driver used is modesetting.

See more about here: ubuntuforums.org.

Doing:

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

will block you from using nvidia proprietary drivers as nvidia-prime is based on modesetting.

But for me, removing xserver-xorg-video-intel fixed the intel tearing issue. If you have Ubuntu 18.04.2, or already moved to Hardware Enablement stack, the command to remove intel driver is:

sudo apt purge xserver-xorg-video-intel-hwe-18.04

As a last resort, you can try to put in /etc/X11/xorg.conf.d/20-intel.conf

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

This didn't affect my nvidia switching capabilities, but I don't use it since I don't need it.

First run all updates and see if that fixes it:

sudo apt update && sudo apt upgrade

And then reboot.

If there are still problems after reboot, try using the PPA:

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update && sudo apt upgrade

And reboot. If problem persists, let me know.
