SYSTEM:
Laptop: ASUS ROG GL552VW
OS: Ubuntu 20.04
GRAPHICS: Nvidia Geforce GTX 960m AND Intel HD Graphics
Linux kernel version: 5.8.0-44-generic
SUMMARY:
From a fresh working install of Ubuntu 20.04, I wanted to downgrade from nvidia-driver-460 by installing nvidia-driver-440 (which actually is a transitional package to nvidia-driver-450). After reboot I couldn't reach login-screen and instead got a black screen.
Problem was that sudo apt-get install nvidia-driver-440 did not insert nvidia modules v450 in kernel since never versions v460 were found.
This was solved by dropping into safe mode and uninstalling linux-modules-nvidia-460 packages and instead installing linux-modules-nvidia-450 packages.
STEPS TO REPRODUCE:
Install Ubuntu 20.04. During installation, allow for the installation of proprietary drivers.
Once Ubuntu 20.04 has started, open a terminal and run the following:
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-driver-440
sudo shutdown reboot now
PROBLEM:
After reboot, you can't reach login screen. Instead you get stuck during bootup.
WORKAROUND:
Remove the linux-modules-nvidia-460 packages and install the corresponding linux-modules-nvidia-450 packages. In my case I had Linux kernel versions 5.8.0-44-generic and 5.8.0-43-generic installed so I did as follows from recovery mode with network:
sudo apt-get autoremove --purge linux-modules-nvidia-460-5.8.0-44-generic linux-modules-nvidia-460-5.8.0-43-generic
sudo apt-get install linux-modules-nvidia-450-5.8.0-44-generic linux-modules-nvidia-450-5.8.0-43-generic
sudo shutdown reboot now
QUESTION:
Why was the linux-modules-nvidia-460 packages installed by the Ubuntu installer to begin with? I ask since I later removed the linux-modules-nvidia-450 packages (OBSERVE: 450, not 460) and used the Additional Drivers GUI to update back to nvidia-driver-460. Now linux-modules-nvidia-460 packages are NOT installed but the following still outputs 460:

SYSTEM:
Laptop: ASUS ROG GL552VW
OS: Ubuntu 20.04.2 LTS
GRAPHICS: Nvidia Geforce GTX 960m AND Intel HD Graphics
Linux kernel version: 5.8.0-44-generic
SUMMARY:
From a fresh working install of Ubuntu 20.04, I downgraded from nvidia-driver-460 by installing nvidia-driver-440 (which actually is a transitional package to nvidia-driver-450 but I didn't know this). After reboot I couldn't reach login-screen and instead got a black screen.
Problem was that sudo apt-get install nvidia-driver-440 did not insert nvidia modules v450 in kernel since never versions v460 were found.
This was solved by uninstalling linux-modules-nvidia-460 packages and instead installing linux-modules-nvidia-450 packages (see WORKAROUND below for instructions).
STEPS TO REPRODUCE:
Install Ubuntu 20.04. During installation, allow for the installation of proprietary drivers.
Once Ubuntu 20.04 has started, open a terminal and run the following:
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-driver-440
sudo shutdown reboot now
PROBLEM:
After reboot, you can't reach login screen. Instead you get stuck during bootup.
WORKAROUND:
Remove the linux-modules-nvidia-460 packages and install the corresponding linux-modules-nvidia-450 packages. In my case I had Linux kernel versions 5.8.0-44-generic and 5.8.0-43-generic installed so I did as follows from recovery mode with network (instead entering recovery mode, you should be able to press CTRL+ALT+F1 from the blank screen after bootup, login with username and password and then running these commands):
sudo apt-get autoremove --purge linux-modules-nvidia-460-5.8.0-44-generic linux-modules-nvidia-460-5.8.0-43-generic
sudo apt-get install linux-modules-nvidia-450-5.8.0-44-generic linux-modules-nvidia-450-5.8.0-43-generic
sudo shutdown reboot now
QUESTION:
Why was the linux-modules-nvidia-460 packages installed by the Ubuntu installer to begin with? I ask since I later removed the linux-modules-nvidia-450 packages (OBSERVE: 450, not 460) and used the Additional Drivers GUI to update back to nvidia-driver-460. Now linux-modules-nvidia-460 packages are NOT installed but the following still outputs 460:

WORKAROUND:
WARNING: BETTER WORKAROUND PROBABLY EXISTS! DON'T JUST COPY-PASTE INSTRUCTIONS. PAY ATTENTION TO WHAT NVIDIA DRVER AND LINUX KERNEL VERSIONS ARE RELEVANT FOR YOU! Run dpkg --list | grep linux-image to see what linux kenrel versions you have installed.
