Public bug reported:
On two different systems with Nvidia driver which upgraded from
6.11.0-8-generic to 6.12.0-12-generic, GUI didn't come up. One laptop
(single monitor) with only Nvidia output tied to a 3200x1800 screen
resulted in blinking white underline cursor in upper left corner, the
other (desktop, dual monitor) fell back to a text login (tty).
Both cases, the switch back to the 6.11 kernel resolved the issue.
initramfs rebuild didn't help.
