Ubuntu 20.04 - Screen Tearing

Question

Since I installed Ubuntu 20.04 I notice that there is Screen tearing when playing videos, it happens in several browsers and it is noticeable when moving the windows within the screen, when scrolling it is also noticeable. How is this problem solved?

Solution 1

I had the same problem with a GTX 960M on my Lenovo ideaPad Y700 and the following worked for me.

Open a terminal and run

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

In the file, write the following line:

options nvidia-drm modeset=1

Save the file. Back into the terminal, update initramfs by running:

sudo update-initramfs -u

Reboot.

If the previous step didn't work, there is another solution that you can try:

$ xrandr --output eDP-1-1 --set "PRIME Synchronization" 1

Reboot.

This command will enable the sync in your hybrid card.

To check that sync has been enable: $ sudo cat /sys/module/nvidia_drm/parameters/modeset

it should return Y now.

Reboot.

Solution 2

1. Try this video to see if you still have screen tearing.
2. Try the solution provided here.
3. What helped in my specific case was that I switched the driver used for my NVIDIA GP107M when using the "Additional Drivers" application and switched from nvidia-driver-440 to nvidia-driver-435.

I have a GT 635M Nvidia card and that steps don't work!

What drivers are you using?

[Juan Pedraza]

I used the private drivers it doesn't work and the free drivers too

[Nandete82]

I amended the solution to include an alternative. Hope it works!

That's because the On-demand uses Intel unless explicitly commanded to use nvidia.

Why is there a need to update "intramfs"?
