Verbose Boot (Kubuntu)

Question! How to make your boot verbose under Kubuntu (possibly same procedure for Ubuntu as well).

Answer! You are going to need to edit the GRUB2 config file to enable verbose mode, so open a console then type the following command :

sudo nano /etc/default/grub

Then find the line that says :

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

And remove the quiet and splash parts so that it reads :

GRUB_CMDLINE_LINUX_DEFAULT=""

Then hold down the CTRL key and push the "o" button, this should overwrite the config file, just push ENTER when asked to save file.

Then run the following command in console :

sudo update-grub

This should update GRUB2 to take the changes into account. Happy reboot!

Note! To exit nano (the editor you ran through console to edit the GRUB2 config file), just hold down the CTRL key and push the "x" key, that should quit nano the editor.
