Lately, booting Ubuntu on my desktop has become seriously slow. We're talking two minutes. It used to take 10-20 seconds. Because of plymouth, I can't see what's going on. I would like to deactivate it, but not really uninstall it. What's the quickest way to do that? I'm using Precise, but I suspect a solution for 11.10 would work just as well.

Easiest quick fix is to edit the grub line as you boot.

Hold down the shift key so you see the menu. Hit the e key to edit

Edit the 'linux' line, remove the 'quiet' and 'splash'

To disable it in the long run

Edit /etc/default/grub

Change the line – GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” to

GRUB_CMDLINE_LINUX_DEFAULT=""

And then update grub

sudo update-grub

  • Removing quiet and splash removes the splash, but I still only have a purple screen with no text. What I want to do, is to see the actual boot messages. – Jo-Erlend Schinstad Jan 25 '12 at 22:25

    Interesting, it does not behave that way for me. At any rate, you can disable plymouth with sudo mv /etc/init/plymouth.conf /etc/init/plymouth.conf.disabled , move it back when you are done. – Panther Jan 25 '12 at 22:32

    Plymouth has to be one of the worst UIs I've come across. It uses the same text box for entering a user name as the password. It looks like you are being prompted for a password so you type it and in plain text is your password for the world to see! – RyanNerd Oct 27 '16 at 07:28
  • @RyanNerd - So disable it or use an alternate – Panther Oct 27 '16 at 15:43
  • @bodhi.zazen This is why I am on this page in the first place is to figure out how to disable Plymouth. If there are better replacements then great. I don't know of any, or how difficult it would be to install a replacement. But my point that for a security login screen Plymouth's UI sucks the big wazoo still stands. – RyanNerd Dec 04 '16 at 10:30
  • @RyanNerd - you are posting a comment on an answer that is almost 5 years old to state you think Plymouth is a security risk and you do not like it? LOL – Panther Dec 05 '16 at 16:51
  • @bodhi.zazen I guess you have a point. Venting about a UI that has been broken for over 5 years is quite useless. :) – RyanNerd Dec 06 '16 at 21:33

If you just want to see the message for a single boot (vs. a permanent change), you should be able to press the ESC key to hide the splash screen and reveal the boot console.

Alternatively to quiet splash kernel parameters alsord.plymouth=0 plymouth.enable=0 kernel parameters can be used.

Either boot and modify parameters in grub console (c) or add to /etc/default/grub:

GRUB_CMDLINE_LINUX="rd.plymouth=0 plymouth.enable=0"

And then regenerate grub config:

# update-grub
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-5.10.0-28-amd64
Found initrd image: /boot/initrd.img-5.10.0-28-amd64
done

How about pressing CTRL+ALT+F2 for console allowing you to see whats going on.. You can go back to GUI/Plymouth by CTRL+ALT+F7.

Don't have my laptop here right now, but IIRC Plymouth has upstart job in /etc/init, named plymouth???.conf, renaming that probably achieves what you want too more permanent manner.
