I've just installed Ubuntu 20.04 on my PC (this is a completely clean install) and I've had nothing but problems. Firstly it would keep booting into GRUB and absolutly nothing in BIOS settings fixed it. I had to reinstall ubuntu to fix it. Now I can't even log in! Everytime i press enter after my password it takes my back to the login screen! Is anyone else having these problems and knows how to fix it?
It seems to be an issue with the auto-login. One way to fix this is by disabling auto-login from the command prompt:
- From the login screen hit
<Ctrl> + <Alt> + <F4>
- Login through the command prompt input:
sudo nano /etc/gdm3/custom.conf
Line number 5 and 6 of custom.conf should be:
where, [username] is the name of the user for auto-login. Change this to:
<Ctrl> + S to save, then reboot by hitting
<Ctrl> + <Alt> + <F1> and selecting restart from the login menu.
