Public bug reported:

My system works fine using vmlinuz-5.15.0-92-generic. When I run
software update and the new kernel vmlinuz-6.5.0-15-generic is installed
I no longer have a dual monitor system. This is the second time this has
happened and I have to return to a prior kernel version to get the
second monitor to work. I noticed that the prior version is using
"GRAPHICS: Quadro 2000/PCIe/SSE2" found in the SETTINGS ABOUT
information and the new kernel is using "GRAPHICS:llvmpipe (LLVM
15.0.7.256 bits)". Both kernels are using the NVIDIA driver metapackage
from nvidia-driver-390(proprietary tested).
