Please help on troubleshooting

Last thing I did was updated the system. `pacman -Syu`

I was able to boot using last initfsram fallback. But i choose to reboot (bad decision)

and now it is not going anywhere.

Grub is getting loaded, my / is encrypted.
I enter the password, it goes to blank screen blinking.

It is just one `-` infront of big black screen.

Where do I start from here.

Dell Laptop with NVIDIA graphics.

I wish to learn this task to survive in production outages..

Re: Please help on troubleshooting

Reinstalling might help

Probably not (unless the system crashed during the update)
Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Re: Please help on troubleshooting

Gnome completely dropped X11 support, but the xorg crash seems to stem from the SDDM takedown.
Hybrid system, no outputs attached to the nvidia GPU.
Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General
