No verbose output on startup after upgrade to 15.04
Solution 1
Log out of your graphical session and go to TTY1 whith Ctrl+Alt+F1.
Log in and edit the file /etc/default/grub
:
sudo nano /etc/default/grub
or if you like vi
:
sudo vim /etc/default/grub
Remove the values for GRUB_CMDLINE_LINUX_DEFAULT
:
GRUB_CMDLINE_LINUX_DEFAULT=""
Then update GRUB and reboot:
sudo update-grub
sudo reboot
Solution 2
Change your line to GRUB_CMDLINE_LINUX_DEFAULT=""
, update grub, and reboot.
Solution 3
If you have parameters other than "quiet splash" you can leave them in the line e.g.
sudo gedit /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1"
change to:
GRUB_CMDLINE_LINUX_DEFAULT="usbcore.autosuspend=-1"
The "usbcore.autosuspend=-1" allows me to place the laptop into suspend and hibernate modes - there is more to that than just these lines look here for more: https://help.ubuntu.com/14.04/ubuntu-help/power-hibernate.html
Don't forget to run:
sudo update-grub
after you make the changes to your grub file. Now you will not have a splash screen and you will see all the verbose boot process lines during boot. The process is reversible if you get tired of looking at the boot processes just add
quiet splash
back into the parameters of the same line.

When I was running Ubuntu 14.10, I was able to view the verbose output during startup and shutdown (which was very useful for me). But now that I have upgraded to Ubuntu 15.04 I get the verbose output on shutdown, but I only get a purple screen, and then an Ubuntu logo with loading dots which can toggle to a black screen on startup.
In the past to achieve the verbose output on both startup and shutdown I did as follows:
- Executed:
sudo vim /etc/default/grub
- Changed the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to this lineGRUB_CMDLINE_LINUX_DEFAULT="splash"
- Executed:
sudo update-grub
- Rebooted
But as this only seems to work on shutdown, how do I get it to also show me the verbose output on startup?

Phil Goetz over 7 yearsThat's no help to me. I'm trying to install Ubuntu, and I can't figure out why it won't install because Ubuntu 16.04 defaults to quiet boot /while booting the install CD/.
