I'm on a relatively new Dell XPS running Ubuntu 18.04. It has an Intel VGA controller and an Nvidia 3D controller.
The laptop got stuck in 960x540 resolution a few days ago, so I installed Nvidia driver v390 via NVIDIA-Linux-x86_64-390.116.run from https://www.nvidia.com/object/unix.html. (Signing the kernel module for secure UEFI boot was an adventure).
EDIT 2: I disabled secure boot, removed the manually-installed nvidia-390, and used
sudo add-apt-repository ppa:oibaf/graphics-drivers && sudo apt update
, followed by sudo ubuntu-drivers-autoinstall instead. This resulted in no change, except the nvidia kernel module is now loaded in gpu-manager.log (noted below).
I disabled Wayland as XDG_SESSION_TYPE, blacklisted nouveau, etc etc.
My system booted successfully and gave me various resolution options last night. However, today, booting the laptop sent me to a black screen (though it made the annoyingly loud sound that the login screen usually makes.)
I managed to Ctrl-Alt-F4 into a terminal and mess around a bit, but to no avail. I ended up being able to start the X server when I booted in recovery mode on my previous kernel version.
EDIT: rebooted into the bad state and got all the actual info, which is now posted below.
Here are the outputs of some relevant commands.

Question
What appears to be happening is that the nvidia drivers load successfully, but for some reason intel drivers aren't being associated with the Intel VGA device, and I have no clue why.
How do I get Ubuntu to bind the intel driver to my VGA card again? Pointers in the correct direction would be helpful.
