How to Enable Ubuntu Boot Verbose Mode

If you want to see detailed boot messages instead of the splash screen when your Ubuntu system starts up, you can enable verbose mode by following these steps:

1. Open a terminal window.

2. Edit the Grub configuration file by running the following command:

   1	sudo nano /etc/default/grub

   This will open the Grub configuration file in the Nano text editor.

3. In the Grub configuration file, look for the line that starts with GRUB_CMDLINE_LINUX_DEFAULT. This line controls the display of the splash screen during boot.

   • To enable the splash screen with condensed text output (the default for the desktop edition), it should look like this:

     1	GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

   • To enable the traditional text display without the splash screen, remove both “quiet” and “splash” so that it looks like this:

     1	GRUB_CMDLINE_LINUX_DEFAULT=

   Choose the option that suits your preference.

4. After making the necessary changes, save the file by pressing Ctrl + O, then press Enter. To exit Nano, press Ctrl + X.

5. Update Grub to apply the changes you made:

   1	sudo update-grub

Now, when you reboot your Ubuntu system, you will either see detailed boot messages (if you removed “quiet” and “splash”) or the splash screen with condensed text output (if you kept “quiet” and “splash”).

For more information and additional details, you can refer to the official Ubuntu documentation on Grub2: Ubuntu Grub2 Community Documentation.

By following these steps, you can customize the boot behavior of your Ubuntu system to either display detailed boot messages or the traditional splash screen.
