Hello everyone!
This forum has been incredible at educating me and solving my problems just by searching/reading around, so thank you! This time I got a problem of my own that I couldn’t find a solution for online.
Yesterday I had my laptop upgrade using yay -Syu and I allowed the upgrade.
/var/logs/pacman.log: https://pastebin.com/Gcz7vtxP
The pacman hook told me to restart my computer since important files were changed. I turned off my computer and after a few hours I turned it on again to discover that lightdm won’t load and and show only a blinking cursor. I couldn’t switch to any TTY session after since the blinking cursor would override it immediately.
I rebooted in to TTY from grub and my first suspect was the new Nvidia driver. I tried to downgrade nvidia-dkms and nvidia-utils using sudo downgrade nvidia-dkms nvidia-utils to the previous version and then restart, it didn’t work, so I upgraded them back to the latest version.
I made sure the driver is loaded and working properly by running nvidia-smi
I never changed anything in /etc/lightdm/lightdm.conf, but did check that logind-check-graphical=true
Tried to look for logs /var/log/lightdm but the folder is empty.
journalctl -u lightdm doesn’t much here is an example of a boot:

systemctl status lightdm just showed that it was dead and whenever I tried to systemctl enable lightdm and systemctl start lightdm I’d get to the same situation again.
I then resorted in to sudo pacman -S sddm systemctl disable lightdm systemctl enable sddm systemctl start sddm which worked and is how I’m posting to the forum now.
