Public bug reported:
upgrade from 22.10 to 23.04 went smoothly on my Dell laptop. I have an
external monitor that on a dock. It works fine in 22.10 but won't
activate properly with 23.04. If I boot with laptop lid closed I get the
grub screen and then, once it boots, neither screen works.
Reverting the kernel back to 5.19.0-40-generic does work as expected,
but the new kernel with 6.2.0-20-generic does not,
