Ubuntu boots to Blank screen after nvidia driver installation

Ubuntu boots to Blank screen after nvidia driver installation. If i remove nvidia driver using recovery options, then it works fine. How do i install nvidia drivers?

I have a new 3090ti which works without nvidia drivers. But I need the real drivers so that I can do other things.

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.
