Ubuntu/Grub2 Verbose Booting

Ubuntu text boot
Print Friendly, PDF & Email

First things first – remember, always back up important system files before editing!

If you want to view the tradional kernel message output when booting into Ubuntu, you can do it as follows:

Edit /etc/default/grub and edit the following line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Change it to:

GRUB_CMDLINE_LINUX_DEFAULT="--verbose nosplash debug"

Then, run the following command

sudo update-grub2

It will likely take a few seconds. Then reboot and you should see the kernel messages written to the screen as with older derivatives of Linux.
