Incidentally enough, I just updated my nvidia drivers. Lemme reboot. Fingers crossed the kernel isn't boned.

Oof. I jinxed myself. Fucking Nvidia.
Did it break for yours too? I'm running Arch so it's on the latest rolling update drivers from Nvidia. I think recently the new driver was switched over to nvidia vs nvidia-dkms. Also, caused some issues with nvidia-utils.
I hope you're able to figure your way out of it. I guess it's time for TTY or chroot?
