||<>|| Starting in Ubuntu 10.04 (Lucid Lynx), the '''pcspkr''' kernel module is blacklisted by default. See [[Bug:77010|this Launchpad bug report]]. = Disabling the System Bell = You know that beep you get when press the wrong key in xterm? Well here is a mini-howto to get rid of the beep (system bell) if it annoys you. == KDE Notifications == In KDE the system bell can be turned off or on by: K Menu > System > System Settings == System-wide == You can stop the PC speaker from beeping by removing the PC speaker kernel module. To do so run the following command in a terminal: {{{ sudo rmmod pcspkr }}} A more permanent way is to disable the loading of the PC speaker kernel module. Add the following line to your '''/etc/modprobe.d/blacklist.conf''' file, to blacklist and stop the module for loading at boot: {{{ blacklist pcspkr }}} To re-enable the bell, comment the blacklist line with a # symbol: {{{ # blacklist pcspkr }}} ''Thanks to the users who investigated this [[http://ubuntuforums.org/showthread.php?t=126746|on the Ubuntu forums]]''
