Ubuntu Silent Boot.md

This guide shall help you out in getting silent boot experience similar to macOS and Windows on Ubuntu on T2 Macs.

1. On the terminal, run

   sudo gnome-text-editor /etc/default/grub
   

2. Change GRUB_CMDLINE_LINUX_DEFAULT="" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash". If this is already done then directly follow step 4.

3. Run

   sudo update-grub
   

4. Now run

   echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash
   

5. Finally, update your initramfs by running

   sudo update-initramfs -u
   

Warnings regarding possible missing firmware for gpu may be ignored. Though you may optionally run the following to minimise the errors :-

git clone --depth 1 --single-branch https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp /home/$USER/linux-firmware/amdgpu/* /lib/firmware/amdgpu
sudo update-initramfs -u
sudo rm -r /home/$USER/linux-firmware

This shall bring the Ubuntu boot logo only and completely remove boot texts on booting.
