I am writing this question to answer the following issues:
After installing Nvidia driver from Software & Updates(Additional Drivers Tab) or Command line, Ubuntu did not start.(Stuck at system LOGO screen or it shows black screen).
I was trying on ASUS ROG Strix G15 Ryzen 7 Octa Core 5800H - (16 GB/1 TB SSD/Windows 10 Home/6 GB Graphics/NVIDIA GeForce RTX 3060) G513QM-HN319TS Gaming Laptop.
