What is that thing with tty2?
TTY is the text console - same thing where you entered inxi -Fza
Please post mhwd -i (on console).
Please post mhwd -li (on console).
you may add this on boot kernel
amd_iommu=on
rcu_nocbs=0_15
You should update at least to kernel 5.10 LTS.
How to do it?
On console:
mhwd-kernel -li
mhwd-kernel -i kernel510
The installed kernel 5.9 might be the cause of the black screen.
The correct is
mhwd-kernel -i linux510
not woking
i mean not solved the problem
I’ll say you should start by updating your system using sudo pacman -Syyu
in the TTY. You can post a photo of the output.
