Screen Tearing with nvidia driver 440.82 and geforce mx250 graphics card (Ubuntu 20.04)

I think i am experience some screen tearing on my Linux machine. I have reinstalled the NVIDIA drivers multiple times. I’ve also watched some videos on how to fix this problem but none of the settings in NVIDIA-settings are available to me
any help is appreciated

Please try kernel parameter

i have but no luck

Where do you experience screen tearing?

Where there is a sudden movement or flashing on my screen

Please run as root and attach the resulting nvidia-bug-report.log.gz file to your post. You will have to rename the file ending to something else since the forum software doesn’t accept .gz files (nifty!).

Here is the file. Extracted it

According to the logs, you’re running in render offload mode so everything is running on the intel gpu unless you specify explicitly to use the nvidia gpu. Do you have tearing in games with offloading?

currently, i switched to the NVIDIA on demand so the tearing would stop. should i switch back to the NVIDIA performance mode

Yes, at least to create a new nvidia-bug-report.log.

give me a minute

Thanks For the help @generix. I believe it has fixed itself

You previously had the 435 driver, now with 440.64, PRIME sync is working again.
