usci_acpi USBC000:00:00 PPM init failed (-110), FIXED but desktop is ONLY shown on EXTERNALMONITOR

Previously: I had Windows 10. Now, I want to do dual boot with Ubuntu 18.04 Bionic with NVIDIA and CUDA. I have installed Ubuntu properly as well as making sure nvidia and cuda working, where I had undergone many steps including

1. https://docs.nvidia.com/datacenter/tesla/tesla-installation-notes/index.html using Package Manager Option, I follow all necessary details meticulously including pre and post installation steps
2. Blacklist the noveau and nvidiafb

After these steps, "nvidia-smi" and "nvcc --version" is showing the correct output. Now, I can see I had a problem with booting as it says usci_acpi USBC000:00:00 PPM init failed (-110). The screen is just dark and I have to get out to tty2 by ALT+F2 ((IT CANNOT ENTER THE OS and login desktop)

My next step is to follow Can't get internal and external monitor working simultaneously with 20.04 on laptop with AMD Ryzen 7 4800H and Nvidia RTX 2060. So, I changed the .conf file of 10-amdgpu.conf and 10-nvidia.conf, and turn primary gpu as on for 10-nvidia.conf Now, I get another problem that I can only use the external monitor screen connected through USBC to show the login ubuntu screen and desktop properly. However, the laptop screen just shows the ASUS logo "IN SEARCH OF INCREDIBLE"

Now, I want my laptop screen to be able to show the screen. Do you have any suggestion how to proceed with this problem? Might this be an ASUS problem or NVIDIA bug?

Laptop: ASUS TUF GAMING A15 FA506QR
AMD RYZEN 5800H (5000 series gen 7)
RTX 3070
