Screen Tearing Ubuntu 18.04

  • 772

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.

    For Firefox do this:

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

  2. 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 }"

  3. 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 debugging, 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 run:

    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.

  4. 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.

  5. I used to have the same problem and I fixed it just simply by changing the refresh rate in the display settings. Instead of using 60Hz I used 59.96Hz

  6. I get fixed by turning off hardware acceleration in browser setting. I experienced youtube tearing every time with every version of anything. My system was Intel i3-4th gen with intel HD graphics.
