Here is what happened.
- I wanted to install Lutris to play games on my laptop (ASUS X756UX, Ubuntu 20.04), and the website advises to check that the graphics drivers are installed and up to date. Being a complete novice when it comes to drivers on a Linux distro, I followed this guide.
- I went to Software & Updates > Other drivers and selected 'NVIDIA driver metapackage from nvidia-driver-510' (I was using the 470 version previously).
- I went ahead with the thing; the old driver was uninstalled and the new one installed, then I was asked to create a Secure Boot MOK password, which I did.
- I rebooted as prompted.
After I logged in, I discovered I have no more sound, no network access, and the touchpad doesn't work.
I can log in, use the keyboard and an external USB mouse.
If I plug in a USB drive, it doesn't automatically mount and it's not even detected by fdisk -l.
I also noticed that the system takes a much longer time to shutdown now.
Also at boot, just before the log in screen, I get the message /dev/sda2: clean, <big number>/<big number> files, <big number>/<big number> blocks, similarly to this problem, except I don't get stuck there.
If I boot from a Live USB Ubuntu 20.04 everything works normally.
As far as I can tell, a lot of modules aren't being loaded ; here is the output from lsmod:

How can I fix this? Did I do anything wrong? Also, how can I avoid this in the future? If nothing works I will reinstall Ubuntu, but I would like to keep this as a last resort.
Thanks.
