How do I disable kernel messages while booting?

Question

I enabled the kernel messages a long time ago because I was playing around with Ubuntu. But now I am finished and I want to disable them again, but forgot how to.

/etc/default/grub already contains the line:

#GRUB_TERMINAL=console

(including the hash which disables it).

The GRUB_CMDLINE_LINUX_DEFAULT definition in /etc/default/grub should contain "quiet splash". You also need Plymouth to be installed.

Check if /etc/default/grub has the line GRUB_TERMINAL=console uncommented. Either open it with any editor, or just run this in the terminal:

cat /etc/default/grub | grep GRUB_TERMINAL

If the output is GRUB_TERMINAL=console without a #, then open the file with sudo -H gedit /etc/default/grub, add a # at the beginning of that line and save. Do not change anything else.
