I can confirm this problem, just updated the system and Xorg session wasn't starting, I was able to install the latest drivers using another tty and enabling the graphics drivers ppa, but, yes, I restarted the computer and saw just a black screen.

This is problematic in distros like Elementary OS 6 as they dont expose the grub menu, so you have the latest kernel version installed only, which will not be able to boot on the graphical interface because there is no driver.
