Public bug reported:
My computer was working this morning, but when I powered it back on this
afternoon the keyboard and mouse do not function.
I have a desktop pc, 3 monitors, encrypted boot drive.
dpkg showed that kernel 5.4.0-74 was installed on my computer this
morning.
When I boot with kernel 5.4.0-74, my keyboard allows me to enter my
decryption password, but my computer boots with one monitor active and
the USB keyboard and USB mouse do not respond. (Using a different USB
keyboard makes no difference. Unplugging the keyboard and plugging it
back in makes no difference.)
When I use GRUB to boot with kernel 5.4.0-73, my system works as
expected (and all 3 monitors light up).
REQUIRED DETAILS:
lsb_release -rd
Description: Ubuntu 20.04.2 LTS
