How can I show or hide boot messages when Ubuntu starts?

TL;DR reconfigure or reinstall GRUB

(assuming you have several OSes installed, like Ubuntu and Windows)

When you power up your computer, one of the first things to start is the boot loader. It’s a relatively small piece of software that boots/loads (see what I did there?) the OS — sets up the CPU in a particular way, copies OS kernel from the hard drive into RAM and does some other minor stuff. Next, it yields the control to the OS it just loaded, so that it can finish booting.

Now, not all the boot loaders are equally smart. The one that comes with Windows only knows how to boot Windows itself. So if you’re recently installed Windows, this is what happens: the Windows boot loader starts, sees your Windows installation and boots it up, without caring a slightest bit about Ubuntu being installed alongside.

The boot loader that comes with macOS (as a part of Boot Camp) knows how to boot macOS and how to yield control to Windows bootloader. It gives you the...

Is there a way to easily turn on/off showing the boot messages (loading the services) when Ubuntu starts? Is it something in Grub2?

I am running 10.04.

You would need to edit the file /etc/default/grub. In this file you'll find an entry called GRUB_CMDLINE_LINUX_DEFAULT. This entry must be edited to control the display of the splash screen.

The presence of the word splash in this entry enables the splash screen, with condensed text output. Adding quiet as well, results in just the splash screen; which is the default for the desktop edition since 10.04 (Lucid Lynx). In order to enable the "normal" text start up, you would remove both of these.

So, the default for the desktop, (i.e. splash screen only):

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" #Hide text and show splash

For the traditional, text display:

GRUB_CMDLINE_LINUX_DEFAULT= #Show text but not the splash

For the splash, but the ability to show the boot messages by pressing Esc:

When Ubuntu boots, you normally briefly see a screen that says “GRUB loading. please wait… Press Esc to enter the menu…”

If you are hacking around your system and would prefer to always see the GRUB menu there’s an easy fix.

Edit the /boot/grub/menu.lst file using the following command

sudo vi /boot/grub/menu.lst

Hide GRUB Menu

By default GRUB Hides the menu .

Now search the section that looks like this

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
hiddenmenu

Show GRUB Menu

Put a # before hiddenmenu to comment that line out

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu

Save the file, and you should see the menu the next time you reboot.

Start-up problems. That moment when – having expected yourself to be getting on with your day's work or entertainment – you find yourself staring at a cryptic error message, or even worse, a blank screen.

No matter how many times you press reset or restart, the same impenetrable barrier blocks your path. So, what can you do? Start-up problems come in all shapes and sizes, and they can be difficult to track down.

There are, however, some sound principles to use that will resolve many errors, and in this tutorial, we're going to look at the tools and techniques required to troubleshoot most start-up problems. You should start by examining how the boot process works.

This reveals that the boot process can be split into three broad stages centred around the Grub 2 boot loader: pre-Grub, Grub and post-Grub. Knowing this allows you to focus your troubleshooting efforts based on where in the process the error or freeze occurs.

Let's start at the beginning. You...

When you freshly set up a Linux distribution by hand, you get a lot of verbose output when booting into your system, but also install'n'go distributions like Ubuntu oder SUSE output some text when loading the kernel. This is not always desired and many people want to suppress these insistent system messages, but it's not as easy as you might think.

Booting your system quietly has some advantages as well as some disadvantages. The following list points out the main arguments for and against silent boot processes. Advantages are:

No unsightly raw text output Feeling of a solid and monolithic system ready to use No confusing messages for ingenuous end-users

On the other hand there are also some disadvantages:

Less control, some errors during boot process might stay undetected No useful error output at all if kernel panics

There might be some other important points I forgot. If you find any other, please don't hesitate to leave a comment on this article....
