Hello,
I would suggest you to do a clean install.
Back up your home folder to a USB stick or elsewhere before installing.
Reinstall, but this time with separate partitions, one for the /root
and one for your /home personal folder.
Since you hadn’t answered the question. proprietary drivers or open source driver?
Take the changes to the /etc/default/grub “nvidia_drm.fbdev=1” and /etc/mkinitcpio.conf (nvidia nvidia_modeset nvidia_uvm nvidia_drm) as others had recommended to me (My Question here in the Forum) then restart.
And other like if you give more info like
inxi -v7azy or so
but rather wait with my answer until others correct my given answer or give you a better answer, since I am only an experienced beginner myself
Greetings
Tony
