I upgraded my OS to Ubuntu 18.04 from Ubuntu 17.10 today after it was released.

The boot stops at a black screen saying nothing just one line, something about my SSD being loaded. The only way to start the OS is removing all the nvidia packages and replacing quiet splash by nomodeset in boot options on grub.

I need to know why this works and how do I fix the problem so that I don't have to do this all the time and start using my Nvidia drivers.

I have nvidia-390 driver installed

    To close voters: according to release schedule of bionic the release date is today, so closing as off topic because of developtment version not applies anymore! See wiki.ubuntu.com/BionicBeaver/ReleaseSchedule – Videonauth Apr 26 '18 at 10:59
  • I am not talking about the development version here. I upgraded my ubuntu today after the final version was released on the update channel of ubuntu. Am I not getting something correct, in that case please clarify – akxer Apr 26 '18 at 11:18
  • Yeah, same problem here, I can't get xorg to work with gdm, and nvidia-390 to work with wayland. I somehow ended up with wayland as default. Either nvidia drivers are broken af, or xorg is broken or both. Upgrade for me was a disaster. – Von Goofy Apr 27 '18 at 9:22

    thank you both, It actually worked and it did startup, but alas reinstalling can't be really the answer. I did reinstall but others might find it very laborious. I keep my files organized because I format a lot, just to keep experimenting with my system – akxer Apr 27 '18 at 17:07

This helped me:

  • Open Terminal and run:

    sudo gedit /etc/default/grub
  • change GRUB_CMDLINE_LINUX=...... to:

  • Delete any extras like nomodeset,acpi=off,etc and after that update grub:

    sudo update-grub
  • Restart.

Of course its better to first test this from grub (while rebooting), editing the starting line (Ubuntu-line) with the e-key.
