Linux has two booting mode, GUI or Verbose/Text mode. A Linux Machine booting with a GUI/Logo on startup seems good. But problem arises when some random process while booting up takes time and you have no idea what is going on behind. Verbose mode not only makes you look geeky, but also helpful about providing information on what is going on.

By default most distros have GUI boot mode enabled and might come with GUI tools to switch Verbose Boot Mode.

In case of unavailability of GUI tools one can edit(Require root Privileges) /etc/default/grub file. Following line need to be changed from

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To

GRUB_CMDLINE_LINUX_DEFAULT=""

After editing the file, run the following command (Require root Privileges)

update-grub
