This is my first question on here so please don't destroy me, i would like to enable a logging off sound when turning off or restarting Ubuntu, i have some custom sounds installed and have managed to get system ready and logging ON to work, however all questions i have looked for regarding this are over 6 years old and don't actually address what I'm trying to do. I have a few different .ogg files and have basically deleted the old ones and pasted in the new.


  • See askubuntu.com/questions/293312 , and look for the excellent systemd-related answer, for how to trigger an event upon logout in 16.04 and newer releases of Ubuntu. – user535733 Feb 19 '17 at 14:31

You can use the program music123 to play the sound

sudo apt install music123

Then create a init file to trigger a file to play

sudo nano /etc/init.d/K01sdsound.sh

In that file do something like

/usr/bin/music123 /yourpath/yourfile.format

Make your file executable

sudo chmod +x /etc/init.d/K01sdsound.sh

Test your file


Now that your file plays a song or sound you need to tell it to run on logoff you can add it to your lightdm config, lets create a new config file

sudo nano /usr/share/lightdm/lightdm.conf.d/50-sdsound.conf

add to this new file


You now have sound on logoff

Or if you want it on shutdown create a symbolic link from your file to /etc/rc0.d so your system runs it on shutdown either/also

sudo ln -s /etc/init.d/K01sdsound.sh /etc/rc0.d/K01sdsound.sh
  • Answers for new versions of Ubuntu should use systemd, not init. – Nonny Moose Feb 19 '17 at 17:58
