Boot Linux without a splash screen

If you prefer to boot up your Linux machine with the boot messages rather than the distro splash screen. You can enable that by editing the file /etc/default/grub and set the value of GRUB_CMDLINE_LINUX_DEFAULT to an empty string.

Example:

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""

After editing the file, execute update-grub to load your configuration into the bootloader.

sudo /usr/sbin/update-grub

Output of update-grub
