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 isfalse
). This forces Hardware Acceleration to turn on. - Change it to
true
by double-clicking. - Save and restart Firefox.

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 }"

2If you have a dual monitor setup, you'll need something like: nvidia-settings --assign CurrentMetaMode="DP-0: nvidia-auto-select +1680+0 { ForceFullCompositionPipeline = On }, DVI-I-0: nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }" Jan 3, 2021 at 2:34

1I believe you can fix this permanently (without setting a startup app). Open NVIDIA X Server Settings app -> X Server Display Configuration -> click 'Advanced' and then set the "Force Composition Pipeline" and "Force Full Composition Pipeline" checkboxes. Apply. To make permanent click Save X Configuration File. (NB for that to work I had to
sudo chmod u+x /usr/share/screen-resolution-extra/nvidia-polkit

Make sure that you have hardware acceleration enabled in your browser and supported by your GPU driver.
Google Chrome / Chromium
- Go to Settings → Advanced → System.
- Check Use hardware acceleration when available.
For debug open this URL (paste it into your address bar):
chrome://gpu/
Firefox
- Go to Preferences → Performance.
- Un-check Use recommended performance settings.
- 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.

1For chrome I needed to also enable flag chrome://flags/#enable-accelerated-video-decode– vozmanDec 3, 2020 at 20:48
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.

1I think, we need to run "sudo update-initramfs -u" command after writing that content as suggested. Unless I am wrong but AM I WRONG?– PranavMay 8, 2020 at 5:24
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
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.

Could you be more specific on how to turn off hardware acceleration? Is it specific to a certain browser? May 4, 2022 at 11:57
