ubuntu 24 에서 로고 대신에 Terminal Booting Log 를 화면에 출력하는 방법을 알아보겠습니다.

$ sudo cat /etc/default/grub 
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`( . /etc/os-release; echo ${NAME:-Ubuntu} ) 2>/dev/null || echo Ubuntu`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
...

위 내용중 아랫 내용을 수정 보완합니다.

#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="text"

변경된 내용 적용하기

$ sudo update-grub
➜  ~ sudo update-grub
