Turn off beep of Xorg

Question

How should I disable beep permanently? I know xset b off can do this, but what's the corresponding option in xorg.conf? Or any other way to do this?

Solution 1

There are a few ways that you could achieve this permanently:

• You could add xset b off to your launch programs (if you are using startx or similar, this will be ~/.xinitrc, otherwise for GNOME/KDE/etc, use your "startup programs" application)
• You could blacklist the module responsible for controlling the PC speaker (and thus also the PC beep), by adding blacklist pcspkr to a file called /etc/modprobe.d/99-nobeep.conf (or similar if your system is not Linux)
• If your system supports it, you could use your audio system to mute the PC beep (ALSA, PulseAudio, OSS, etc)

I do not believe that there is an option for this in xorg.conf.

Another solution, copied from http://ubuntuforums.org/archive/index.php/t-126746.html.

If you want it to not beep in console without going to the extreme of blacklisting the module for the speaker add this to /etc/rc.local

for i in 1 2 3 4 5 6
do
setterm -blength 0 > /dev/tty$i
done

The other solution I've seen around is to add this to /etc/profile:

setterm -bfreq 0

Solution 3

If you want to switch it off permanently you should disable the corresponding modules in /etc/modprobe.d/blacklist.conf:

blacklist pcspkr
blacklist snd_pcsp

This is the default in many distros.
