## How to take out the system built-in beeper in Linux

By admin | December 18, 2009

Usually the system beeper (not to be confused with speakers) can be a rather useful tool in informing or alerting the user. Sometimes however, the beeper can be just plain annoying, especially if you already know what you are doing. For example, it is very annoying to have a laptop suddenly start beeping in the middle or a presentation or on a subway train. Here’s how to disable it to avoid such embarrassment.

To permanently disable:

Execute in a shell (Applications >> Terminal):

echo -e "\nblacklist pcspkr\c" >> /etc/modprobe.d/blacklist.conf

To temporarily disable:

Execute in a shell (Applications >> Terminal):

sudo modprobe -r pcspkr
