After a power outage, my ubuntu 20.04 boots from the normal option in grub to a black screen and hangs there.

However, if I go to Advanced Options and select recovery mode and then "resume", it is able to boot up.

What went wrong? how can I fix it?

Note: I found many solutions to this problem, not all worked for me so I figure that there are many things that could go wrong. It might be nice to have many optional solutions listed in the answers for this problem :)

The solution that worked for me was reinstalling all the nvidia drivers.

  • Uninstall all nvidia drivers (based on this answer)

    sudo apt-get remove --purge '^nvidia-.*'
    sudo apt-get install ubuntu-desktop
    sudo rm /etc/X11/xorg.conf
    echo 'nouveau' | sudo tee -a /etc/modules
    
  • Reinstall all nvidia drivers (based on this thread)

    ubuntu-drivers devices
    sudo ubuntu-drivers autoinstall
