AFAICT xclock chimes on my desktop (non-randomly) even though I don't specify -chime when it starts. On my laptop (used in silent environments) I have this file: $ cat /etc/modprobe.d/whatever-you-like-to-name-it.conf # blacklist PC Speaker, particularly on the # laptop where it is far too strident blacklist pcspkr blacklist snd_pcsp # $ That should allow you to eliminate the beeper as the source.
