Stop the System Beep

From Knowledge76

HowTo: Turn off (mute) system beep

For anyone with a laptop who works in a library or other quiet area, system beeps every time you press the backspace key one too many times, or just using emacs, can be quite disturbing.

The GUI Way

In Hardy and Intrepid, you can open System -> Preferences -> Sound then go to the System Beep tab and uncheck "Enable system beep".

The Command Line Way

To shut them off: open an xterm or terminal, and enter the two lines

xset b off b 0 0 0 

Hope this helps.

There's also another way:

(as root)

rmmod pcspkr 

This removes the (annoying) pc-speaker driver. To load it back, just type:

(as root)

modprobe pcspkr
