it says firmware load failed then boots to a black screen, if you do Ctrl alt F4 it opens a non gui terminal.
Ok, so I would try to re-install the GUI / Desktop:
sudo apt update sudo apt upgrade sudo apt autoremove sudo apt remove ubuntu-desktop sudo apt autoremove sudo apt install ubuntu-desktop
sudo apt-get install ubuntu-gnome-desktop
or. one could try
sudo apt-get install --reinstall ubuntu-gnome-desktop
or whatever desktop you have (can be xfce4, kde, or something else although I have not tried all of the options, but xfce4 seems to work flawless.)
Edit: related Reinstall Gnome
Just in case this wouldn't work for someone in the future:
- You can always try to install another (different) GUI/Desktop: Like LXDE, and from there (when you have a working GUI/Desktop) Maybe try different things?
Extremely glad it worked and that I could help!
Note: I have noticed that
*This seems to be a very, very common problem (Because I have often, and some of my friends - had this problem, some other problem that (in my case) was after this worked; was the Ubuntu was laggy, but in my case it resolved itself to just, install drivers & update the OS and reboot.
(In case this would be the issue after, this could be a good thing to try)*
Edit: If some has problems with installing drivers
(e.g Nvidia) I would highly suggest checking out Smaili's Great answer here - (Since it's the same version, too - and driver problems can often come after a solution like this above)
