How to disable the pc speaker (beep!)
Get rid of the annoying beeps in Linux
Remove the pc speaker modules "pcspkr" and "snd_pcsp"
You might have only one of these modules in use, but they both enable beeps.
Open a terminal and issue this command as root:
# modprobe -r pcspkr snd_pcsp
To prevent the "pcspkr" and "snd_pcsp" modules from loading again at startup add them to modprobe's blacklist in /etc/modprobe.d/blacklist. You can do this with the following command:
# cat <<END >>/etc/modprobe.d/blacklist
If this does not feel comfortable, you can also edit the aforementioned file with your favorite text editor and add the blacklist lines yourself.
New kernels: remove via !<module>
In the new linux kernels, the use of file /etc/modprobe.d/blacklist is is deprecated. The correct solution is to put a ! in front ov every module you want to blacklist. For instance, in ArchLinux you just have to modify your /etc/rc.conf according to the following:
MODULES=(!pcspkr !snd_pcsp <other modules>)
Re-enabling the pc speaker
The speaker can be temporarily activated by loading either of the modules:
# modprobe pcspkr
# modprobe snd_pcsp
If you do not want to prevent the modules from loading during startup, delete the two blacklist lines mentioned in the previous section from /etc/modprobe.d/blacklist.
Disable console beeps in /etc/inputrc
Another solution is to disable console beeps in /etc/inputrc (change with your favourite editor, should work on all distributions)
# do not bell on tab-completion set bell-style none
Disable the system beep in Gnome
In Ubuntu 7.10 and later, uncheck:
- System > Preferences > Sound > System Beep > Enable System Beep
Or if it's just the terminal tab auto-completion that's bothering you, uncheck:
- Terminal > Edit > Current Profile > Terminal bell
Dr. Thinkpad; Or: How I Learned to Stop Worrying and Love the Beep
Actually, these beeps are quite useful sometimes (especially with shell-scripts that want to get your attention with echo -e "\a" ). The reason people tend to hate them are because they get overused.
1. Make bash tab-completion less beepy, by editing /etc/inputrc (or ~/.inputrc). Add:
# Show all if ambigious. set show-all-if-ambiguous on
This makes tab-completion more useful, as well as less irritating: we now only get a beep on a true error (no possible completions); if multiple options are possible, all are printed, and it doesn't beep.
2. Make the beep quieter, shorter, and a nicer pitch. I tend to set 440 Hz, 50ms. Configure with kcontrol (in KDE), or just use xset in your startup files:
xset b 50 440 50
