Comment 4 for bug 1883727

So. After a set of tests I realized in the following.

1. Install process finished successfully if I use acpi=off flag. But
- the system does not restart on "sudo restart now", it goes to "Reached Restart Target" and hangs.
- when I change later in grub acpi=on , the suspend operation does not work; "sudo restart now" still does not work.
- i do not specify any acpi=off to install Pop!OS 20 (it's sad it's based on ubuntu 20.04), and it works fine with suspend option at start.

2. When i install the system on SSD (with acpi=off) then it fails at the very end with the message like "file system has not been finalized". (But in Pop!OS 20 it is done fine again)

3. After the install it is detected and used nvidia graphic card and the system works ok, then i switch to intel's one and back to the nvidia, then the system does not start. Also, nvidia-settings in Ubuntu 20 show only "PRIME PROFILES" section ( and there is a message in the terminal about it can not load info ), but in Pop!OS 20 there is a full info about nvidia card.

4. Also there is a login issue when it shows a login field on the screen with other applications on the screen, and it does not log in even if the password is correct. I'll try to upload video later.
