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
nvidia-drm.modeset=1
i have but no luck
Where do you experience screen tearing?
Where there is a sudden movement or flashing on my screen
Please run nvidia-bug-report.sh 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!).
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
Ok.

Please try installing the latest 440.82 driver from repo or graphics ppa
https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa
I’ve got the repo. what is the code to install it?
done it
Please create a new nvidia-bug-report.log with gpu switched to nvidia.
You previously had the 435 driver, now with 440.64, PRIME sync is working again.
