Ubuntu Budgie 20.04 here. When booting, my screen shows
⋅ first UEFI bios, shortly
⋅ then Grub to choose OS
⋅ finally Budgie animated logo ( plymouth start screen )
Hitting [Esc] key during that animated logo used to show the « textual » booting screen, sometimes helpful to see what is slowing down the boot.
Actually hitting [Esc] only seems to stop the animation process ( dots under logo are no longer moving ) but does not show the « behind » textual screen.
