Went to System Settings -> Sound and nada. Ubuntu Tweak does't appear in the Software Center anymore. How can one disable these dang bongos in 16.04?

At the login screen use the icon in the upper right to mute the sound. The setting is persistent.

  • Hm... seems fragile to me. Prone to mischievous or clumsy people unmuting it.

    What a nightmare scenario! Thanks for raising this concern. Commented Dec 31, 2019 at 18:31

The file that plays when the login screen is shown is:


Delete or rename it to prevent the sound from playing altogether, or replace/redirect it to make another sound play instead.

AFAIK this is not unique to 16.04, so this should also apply to all other versions of Ubuntu.

    Deleting or replacing system files should be discouraged. Those files will be overwritten with every update. There must be a better solution.

    @IvanPerez do you have a source for that knowledge? These are such trivial and old files that I doubt they're included in the update diff.

    Well, you don't really control what those upgrades will bring. An upgrade that follows all guidelines, passes lintian, and only affects the files it owns, could still undo your changes. And do you consider it a good setup that, if you re-install a package, you "break" things? (By break I mean that a feature no longer works, in this case, the chime being disabled is the feature). (I know my message sounds very direct, but I don't mean it as an attack.) In my case I muted the volume in the log-in screen and the change was permanent and independent from my settings once I log in.

    When it comes right down to it, an update could wipe system files, preferences, user data, et al if it wanted to (or if it's created poorly). I agree this is not an ideal solution, but it is the one I've been using and works reliably for me (and has for many years). If you have a better solution that's guaranteed to be persisted between updates, please write that as your own answer and I'll certainly +1 it!

    As other solutions suggest, all you need to do is to mute the sound in the login screen. The setting is persistent, and it does not affect sound volume after logging in. This worked for me.

I'm Using Ubuntu 16.10. The answer is surprisingly simple. From the Login screen, mute the sound (the setting is positioned in the top right corner) and that's it. Muting the login screen sound does not affect your session sound. I suggest you also try this for other versions of Ubuntu before installing additional software or tweaks.


If the audio-icon is not visible at the login screen, try restarting the system. I have a fresh install of Xenial, and the audio controls only show at startup on initial boot, not on subsequent logouts.


I found that this sound is played due to /usr/share/gdm/autostart/LoginWindow/libcanberra-ready-sound.desktop file, which is provided by gnome-session-canberra package. It says in description that it provides startup/shutdown sounds. Unfortunately, it's not possible to remove this package without breaking ubuntu-desktop package.

There are no knobs or settings to fix this issue.

The least invasive thing I found was to add X-GNOME-Autostart-enabled=false into /usr/share/gdm/autostart/LoginWindow/libcanberra-ready-sound.desktop file.

I'll file some bugs about this (package should be removable without dependencies break, and there should be some normal way to disable sounds through symlinks in /etc or separate settings).

PS Bugs: https://bugs.launchpad.net/ubuntu/+source/libcanberra/+bug/840858 https://bugs.launchpad.net/ubuntu/+source/ubuntu-meta/+bug/1714764

  • You might want to note that your answer is gnome specific as the content of the libcanberra-ready-sound.desktop file indicates.. For the modify symlinks solution see my answer

In both 14.04 and 16.04 /usr/share/sounds/ubuntu/stereo/system-ready.ogg is actually a link to dialog-question.ogg as seen below.

This being the case modifying the link isn't really modifying a system file, it's modifying a pointer to a system file. It should be simple enough to point it elsewhere to the ogg file of your choice. for instance the slightly more pleasant service-login.ogg with ln -sfT service-login.ogg system-ready.ogg or you could rename or delete the link nullifying it's usefulness but I would prefer to simply repoint it to something I might want to hear.


Testing on 14.04 and 16.04 with Unity DE.




I believe the appropriate way to do this would be with a sound theme. You could create a theme that plays a blank or silent .ogg file for this sound. See this answer regarding theme creation.


I had disabled the login sound as suggested by Organic Marble, but I would still occasionally get a loud chime when I hit the splash screen. It was an absolute PITA to diagnose because it would only happen sometimes. I eventually worked out that it was happening when I had connected or disconnected my power cable while the laptop was suspended AND if the laptop sound wasn't muted. When the laptop reactivated, it noticed the (dis)connect at the same time the splash screen came on.

I couldn't find a setting anywhere that would disable that chime, so I ended up going with a variant of Ben Leggiero's answer and renaming files:


Create a backup of the sound, delete it and replace it with an empty file

cd /usr/share/sounds/ubuntu/stereo/
sudo cp system-ready.ogg system-ready.ogg.back && sudo rm system-ready.ogg

To turn it back on

cd /usr/share/sounds/ubuntu/stereo/
sudo cp system-ready.ogg.back system-ready.ogg && sudo rm system-ready.ogg.back
