How to disable the pc speaker (beep!)

Get rid of the annoying beeps in Linux (Xubuntu 6.10 Edgy Eft): Remove the pc speaker module.

Open a terminal and issue this command as root:

rmmod pcspkr

To prevent the pcspkr module from loading again at startup, open /etc/modprobe.d/blacklist with your favorite text editor (as root) and add following lines to the end of the file:

# disable the **** pc speaker
blacklist pcspkr
