The previous kernel 5.15.0-40 worked, at least in regards to having a working 
UI for me. It had other problems that I didn't get around to reporting yet 
(such as no network nor bluetooth being available). Should I report separate 
bugs for these?
I am currently using the kernel version 5.15.0-39 since that is the latest 
kernel version where everything works as expected.

When I press Ctrl+Alt+F1, nothing happens. When I press Ctrl+Alt+F4 I
get to the terminal which I use to login and run all the commands.

I attached the journal and lspci files.

In terms of rebuilding the nvidia driver, that didn't make a difference.
Neither nvidia-dkms-470 (which I apparently was using) nor switching to
nvidia-dkms-515 and rebuilding that.
