Screen Tearing on Ubuntu 20.04 with XPS15 (9500)

This is what I see when I run a screen tearing test video:

I am running NVIDIA driver version 460.32.03 and the XPS15 contains the graphics processor GeForce GTX 1650 Ti.

I have already tried:

• Switching the driver from version 460 to 450
• Save an X Configuration file with nvidia-settings and add the following params to the Screen Section: Option "metamodes" "nvidia-auto-select +0+0 {ForceFullCompositionPipeline=On}"

Info: I can't select FullCompositionPipeline in the nvidia-settings GUI like some solution approaches suggest, because it is not there, even if I select Advanced... see screenshot:

Any other solutions?

Solution 1:

The following solution worked for me.

Create this file:

sudo nano /etc/modprobe.d/nvidia-drm-nomodeset.conf

Add the following line to it: options nvidia-drm modeset=1

Save the file and then run this command in the terminal:

sudo update-initramfs -u

And reboot.

EDIT: Upgrade to the newest Nvidia driver 470, it will also bring some improvements. With the above solution screen tearing disappeared to about 95% in my case, but here and there it was still present, but now I have the feeling it is completely gone.
