I know some of these words ↓

dmesg (Display message or driver message) is a command which will show Kernel ring buffers. These messages contain valuable information about device drivers loaded into the kernel at the time of booting as well as when we connect a hardware to the system on the fly. In other words dmesg will give us details about hardware drivers connected to, disconnected from a machine and any errors when hardware driver is loaded into the kernel. These messages are helpful in diagnosing or debugging hardware and device driver issues. Already covered command in the series is

sudo dmesg

This is how you remove a package using the terminal like a boss

sudo apt-get purge htop

It takes 20 seconds until the Ubuntu logo appears and another 25 until the login dialog.

What I’ve tried:

sudo vi /etc/default/grub
-- GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
++ GRUB_CMDLINE_LINUX_DEFAULT=""
sudo update-grub

sudo vi /etc/default/grub
-- GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
++ GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"
sudo update-grub
