With all of the changes in Ubuntu’s desktop over the past few months, it might seem remarkable that Ubuntu’s logon sound has been basically unchanged in 5 years. The sound theme was designed by a community contributor named Peter Savage. Back in those “edgy” days, Ubuntu had more of an African flavor which is of course reflected in the sound theme. (Peter also has contributed to Edubuntu and wrote Emblem Divide, a sci-fi book distributed at no cost but the author encourages readers to contribute to charities.)
I had only been using Ubuntu for a few months at that point so I have a hard time remembering what the earlier sound theme was (which had been introduced for Ubuntu’s first release, Warty Warthog in 2004). For historical reference, here are the sound clips:
For a while, I was thinking that Ubuntu should have a community contest similar to the wallpaper and countdown banner ones. More recently, I think that it would be better not to have a login sound at all. How many of us have had our computers (Ubuntu, Windows XP or whatever) or cellphones loudly announce to everyone that they have been turned on, too often at the wrong time? I think a historical reason for the logon sound was because computers used to take a long time to turn on. Fortunately, Ubuntu boots pretty quickly these days so that reason is obsolete.
Today, I uploaded a new version of libcanberra to Precise (12.04) which disables the login sound by default:
* 02_disable_login_sound.patch: - Disable the login sound by default, since it seems to be more disruptive than helpful especially with faster boots
If you still like hearing the login sound, click Startup Applications in the system menu at the top right of your computer and make sure the GNOME Login Sound box is checked. (Or if you're using Ubuntu 11.10 or earlier and don't like it, make sure that box is unchecked.)
I'd like to close by reminding you that it's possible to contribute to Ubuntu without being a Canonical employee and without even being a programmer. You contributions can have a big impact like Peter's 7-second composition which has been heard by tens of millions of people since 2006.
