After applying the latest updates for focal yesterday and rebooting, the
internal display of my laptop is no longer usable. Only a noisy, snowy
image can be seen on the display. An externally connected display still
works.
I can reproduce this behavior on 2 laptops:
TUXEDO Pulse 14 - Gen1
AMD Ryzen 7 4800H
ThinkPad T14s AMD Gen 1
AMD Ryzen 5 Pro 4650U
