So I have recently switched to Ubuntu 18.04. LTS and I'm getting a lot of screen tearing especially during video playback on e.g. YouTube. Could anybody help me fix this? Note that I'm completely new to Linux.

    What's your video card? Nvidia, AMD, or Intel? – SurvivalMachine May 7 '19 at 17:04

    Have you installed any video drivers? Open Software & Updates, Additional Drivers tab, and tell me what you see. – heynnema May 7 '19 at 18:46

For Firefox do this:

  • Type "about:config" on the address bar.
  • Search for layers.acceleration.force-enabled (default is false).
  • Change it to true by double-clicking.
  • Save and restart Firefox.

Make sure that you have hardware acceleration enabled in your browser and supported by your GPU driver.

Google Chrome / Chromium

  1. Go to Settings -> Advanced -> System
  2. Check Use hardware acceleration when available

For debug open this URL (paste it into your address bar):

chrome://gpu/

Firefox

  1. Go to Preferences -> Performance
  2. Un-check Use recommended performance settings
  3. Check Use hardware acceleration when available

For debug open this URL (paste it into your address bar):

about:support

and look for Graphics info

Checking GPU drivers

To check what driver is in use open terminal and type:

lspci -v | less

then press /, type VGA and press ENTER

In the VGA section you'll see your video card model, available drivers and drivers in-use.

Example:

01:00.0 VGA compatible controller: NVIDIA Corporation [GeForce] (rev a1) (prog-if 00 [VGA controller])
(...)
        Kernel driver in use: nvidia
        Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia

Depending on your graphics card you may want to switch between open source and proprietary driver.

Open source drivers are better for 2D rendering, but have lower performance for 3D acceleration.

Switching drivers

Go to System settings -> Updates -> Settings -> Additional drivers.

You should be able to also open this tab via terminal with:

/usr/bin/python3 /usr/bin/software-properties-gtk --open-tab 2

Then you can switch between drivers, then reboot your PC.

Intel graphics

For Intel integrated graphics go to https://01.org/linuxgraphics/downloads/

There is a video here that fixed it for me. The short version for Ubuntu 19, is that I had to open "Startup Applications" and add a new item with the command:

nvidia-settings --assign CurrentMetaMode="nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"

  • This helped on Kde Plasma with tearing when dragging windows and also on chrome when scrolling and watching videos. – Ralf May 25 at 10:02

If you have an Intel driver (check with lspci command) simply create a file:

/etc/X11/xorg.conf.d/20-intel.conf

with content:

Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
EndSection

Then reboot.

This helped me to remove screen tearing and flickering.

  • I think, we need to run "sudo update-initramfs -u" command after writing that content as suggested. Unless I am wrong but AM I WRONG? – Pranav May 8 at 5:24
