Install Ubuntu 20.04 on Asus G15

I'm a frequent user of Ubuntu since 14.04. I have a hard time installing Ubuntu 20.04 on my new laptop. I have done the following.

• Disable Fast Boot in BIOS
• Disable Secure Boot in BIOS
• Make sure SATA connection is selected with the PCIe NVMe SSD
• Install Ubuntu 20.04 LTS on a USB drive via Rufus

A few specs about my laptop:

• Asus G15
• AMD R7-5800H
• NVIDIA GeForce RTX 3050 Ti
• SSD

In the Grub menu, press e and put in nouveau.modeset=0 as described in here (if this is not done, then the resolution is 800x600 and I will have a harder time navigating with the unseen bottom of the install windows). All in all, it says I finished the installation. My problem is that it can't boot from the installed Ubuntu, it would just give me a black screen and do not advance from there. I have tried various ways, but I don't seem like I can break through here. Please let me know if there is anything else I can do to make this dual boot.

Update 1:

It actually works in Recovery Mode but not Normal Mode. I don't know why (perhaps the Nvidia drivers are not correct), but the installation procedure looks correct.

So these are the steps I follow to install Ubuntu 20.04 on Asus G15. The culprit is the graphics driver.

1. install without checking "Install third-party software".
2. boot in recovery mode
3. enable Networking
4. sudo add-apt-repository ppa:graphics-drivers/ppa
5. sudo apt install nvidia-prime
6. sudo apt update && sudo apt upgrade
7. create /etc/modprobe.d/blacklist-nvidia-nouveau.conf

blacklist nouveau
options nouveau modeset=0

8. edit /etc/default/grub and append nomodeset after quite splash
9. sudo update-grub
10. sudo reboot now

Notes:

1. I'm not sure if any commands above can be ignored.
2. Since you are logging in as a root shell, sudo is not required (because you are already a root user).
3. There are possibilities to install proprietary drivers

sudo ubuntu-drivers install

or

sudo apt install nvidia-driver-460

but I did not take risks.

4. I have seen stuff like this or this, which may be helpful, but probably not mandatory. It is still good to know though.
