In /etc/default/grub when I change splash to nosplash and run update-grub, after a reboot, everything is super laggy (e.g. if I type a letter, it takes 10 seconds for the letter to appear).
And yes, I have already tried reverting back to splash to ensure this was the cause.
Why and how do I fix this?
P.s. I need "nosplash" because of this issue: During boot, the OS would request my password to decrypt my disk but wouldn't detect my input. I tried following this solution: Cannot enter password to start Ubuntu
