This post has 3 aims :
1.Share my solution for people to avoid them spending their evening searching like I did.
2.See if anyone can share insight on what happened and why having a capability denied for my graphical interface solved the issue?
3.Ask if this can be suggested as a bug to the RedHat team
Scenario :
Normal install of Centos Stream 9 on my old machine.
All good, it goes through until the end, no error.
Reboot the machine.
Instead of login screen I get the little white spinning wheel at the start, and then it goes all black with just the cursor of the mouse.
I go ctrl+alt+F1 to get text based login screen
I log in
Here are the errors I got :
Here is details of my graphical interface :
Code: Select all

We can see following error from time to time in the terminal just popping :
Code: Select all
nouveau 0000:04:00.0: bus: MMIO read of 00000000 FAULT at 619444 [ PRIVRING]
This involves first of all to blacklist the use of nouveau and then generate a new grub config file.
I do so.
Then reboot.
And there, without even installing anything, login page appears, all works now fine, only difference? Now we see the blacklist of the graphical interface
