Assuming that this is Ubuntu 20.04...

From the GRUB menu, choose Additional Options, then Recovery Mode, Root Access.

At the # prompt:

mount -o remount,rw /

sudo update-alternatives --config default.plymouth

enter image description here

Choose the ubuntu-logo choice, then repeat the command with the bgrt choice.

sudo update-initramfs -c -k $(uname -r)

Then reboot.

  • In my case, Lubuntu 20 04, it boots and says [ok] for Finished Terminate Plymouth Boot Screen.Then nothing. With Alt-F1 I can go to tty1, but Lubuntu will not start in GUI. With Ctrl Alt F7 I get back to the Plymouth message, but no gui.

  • In my case issue was arised because of SELinux. To resolve it I removed string with selinux in the etc/default/grub , apply changes update-grub and restart my pc. It works then. More info : askubuntu.com/questions/1328085/…

  • @arunpal SELinux doesn't belong in /etc/default/grub anyway. Who put it there?
