LKBEN11393: Ubuntu Linux, how to enable boot messages during startup


When booting your linux system, you do have a blank screen till the gui starts


This is a configuration which can be changed. The default ist quiet and splash.


To change this configuration you need to edit the grub configuration. On Ubuntu this can be done via /etc/default/grub. You can use any editor you like.

sudo vim /etc/default/grub

Now you locate the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and delete the parameters. You should now have the following line in your configuration:


I also like to change the GRUB_TIMEOUT_STYLE to countdown and to set the GRUB_TIMEOUT to 10.




After your changes you need to execute the update-grub command to update your configuration.

sudo update-grub


This article has been checked and works on Ubuntu 20.04.1 LTS and also on 21.10. Please note that after these changes you might see the following error:

can't find HWMATCH

This error can be ignored. (it was there in quiet mode too) If you want to complete disable this error, you need to update your configuration in /etc/grub.d/10_linux by commenting a few lines out.

Have fun.
