Install problem of ubuntu 20.04 on Lenovo slim5 14-ITL

Question

Laptop spec:

	Details
Name	Lenovo Ideapad Slim5 14-ITL 5D M16
CPU	Intel i5-1135G7 (Tigerlake, 11th)
GPU	NVIDIA Geforce MX450 2GB
RAM	16GB DDR4 3200MHz

I want to install Ubuntu on my new laptop, Lenovo Ideapad Slim5 14-ITL. After installation of Ubuntu 20.04, however, only the following error message appeared, and Ubuntu didn't turn on.

[ 4.001152] Bluetooth: hci0: Failed to send Intel_Write_DDC (-22)
[64.610552] sof-audio-pci 0000:00:1f.3: error: no reply expected, received 0x0
[64.714001] skl_hd_dsp_generic skl_hda_dsp_generic: ASoC: failed to init link iDisp1: -517

I cannot search about my problem exactly, so I write this question.

Can you do me a favor?

This seems to work:

• First, boot Ubuntu in recovery mode.

  With BIOS, quickly press and hold the Shift key, which will bring up the GNU GRUB menu. (If you see the Ubuntu logo, you've missed the point where you can enter the GRUB menu.) With UEFI press (perhaps several times) the Escape key to get grub menu. source

• Then, open a terminal and run:

  cd /etc/default
  

• Next, edit the grub file with sudo, i.e.:

  sudo vi grub
  

  or

  sudo pluma grub
  

• Look for the line:

  GRUB_CMDLINE_LINUX_DEFAULT="..."
  

  and change it to:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
  

• Save the file.

• Then in terminal run:

  sudo update-grub
  

After that, I could boot Ubuntu normally.
