Ubuntu 9.04 – Disabling system beep at shutdown

Despite volume controls being set to mute and sound theme set to “No Sounds,” the stupid system speaker still issues a quick succession of beeps when I shut down my Dell Vostro 1520.

I really don’t care to hear anything the system speaker has to say.  So I disabled it altogether.

Here’s how:

gksudo gedit /etc/modprobe.d/blacklist.conf

At the bottom, add the following line:

blacklist pcspkr

Reboot.  Log in and the next time you shutdown, the speaker should not beep.
