How To Deactivate Plymouth Boot Screen in Ubuntu

Ubuntu 13

Ubuntu is a popular Linux distribution known for its user-friendly interface and robust performance. However, sometimes users may want to see the detailed boot messages instead of the Plymouth boot screen, which is the default graphical boot animation. This article will guide you through the process of deactivating the Plymouth boot screen in Ubuntu.

Quick Answer

To deactivate the Plymouth boot screen in Ubuntu, you can temporarily hide it by pressing the ESC key during boot. For a permanent solution, you need to edit the GRUB configuration file by removing the "quiet" and "splash" options. Save the file, update GRUB, and the Plymouth boot screen will be deactivated.

What is Plymouth?

Plymouth is the application that provides a graphical boot animation while the system is booting up. It’s designed to be a visually-appealing way to mask the technical details of the boot process.

Why Deactivate Plymouth?

There are several reasons why you might want to deactivate Plymouth. For instance, you might be troubleshooting a problem and need to see the detailed boot messages. Or, you may simply prefer the text-based boot console to the graphical boot animation.

Temporary Deactivation

The simplest way to deactivate Plymouth is to press the ESC key during boot. This will hide the splash screen and reveal the boot console. However, this is a temporary solution and Plymouth will be active again the next time you boot.

Permanent Deactivation

For a permanent solution, you will need to edit the GRUB configuration file. GRUB, or the Grand Unified Bootloader, is the default bootloader for Ubuntu.

Editing the GRUB Configuration File

To edit the GRUB configuration file, open a terminal and type the following command:

sudo nano /etc/default/grub

This command opens the GRUB configuration file in the nano text editor. The sudo command is used to execute the command with root privileges, as the GRUB configuration file is a system file that can only be modified by the root user.

Modifying the GRUB Configuration

In the GRUB configuration file, find the line that reads:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

This line tells GRUB to boot with the “quiet” and “splash” options, which suppresses detailed boot messages and enables the Plymouth boot screen, respectively.

To deactivate Plymouth, you need to remove these options. Change the line to:

GRUB_CMDLINE_LINUX_DEFAULT=""

Then, save the file and exit. In nano, you can do this by pressing Ctrl+X, then Y to confirm the save, and finally Enter to confirm the file name.

Updating GRUB

After modifying the GRUB configuration file, you need to update GRUB for the changes to take effect. To do this, run the following command in the terminal:

sudo update-grub

This command generates a new GRUB configuration based on the modified file.

Conclusion

By following these steps, you can deactivate the Plymouth boot screen in Ubuntu. Remember, if you ever need to re-enable Plymouth, you can simply reverse the changes made to the GRUB configuration file and run sudo update-grub again. Happy tinkering with Ubuntu!

How can I reactivate the Plymouth boot screen in Ubuntu?

To reactivate the Plymouth boot screen, you can simply reverse the changes made to the GRUB configuration file. Open the file using sudo nano /etc/default/grub, modify the line GRUB_CMDLINE_LINUX_DEFAULT="" back to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash", save the file, and run sudo update-grub to update GRUB.

Can I customize the Plymouth boot screen in Ubuntu?

Yes, you can customize the Plymouth boot screen in Ubuntu. There are various themes available that you can install and apply. You can find these themes in the official Ubuntu repositories or on community websites. Once you have installed a new theme, you can use the sudo update-alternatives --config default.plymouth command to select the desired theme, and then run sudo update-initramfs -u to apply the changes.

Is it possible to disable Plymouth temporarily for just one boot?

Yes, it is possible to disable Plymouth temporarily for just one boot. During the boot process, you can press the ESC key to hide the splash screen and reveal the boot console. This will disable Plymouth for that particular boot only. On subsequent boots, Plymouth will be active again.

Can I see the boot messages while Plymouth is active?

By default, Plymouth suppresses the detailed boot messages to provide a graphical boot animation. However, you can view the boot messages even with Plymouth active by pressing ESC during boot. This will hide the splash screen and display the boot console, allowing you to see the messages.

Will deactivating Plymouth affect the performance of Ubuntu?

Deactivating Plymouth will not directly affect the performance of Ubuntu. Plymouth is primarily a cosmetic feature and disabling it will not impact the functionality or speed of the operating system. However, keep in mind that without Plymouth, you will no longer have the graphical boot animation and will instead see the text-based boot console during startup.
