[request-sponsor] disable console bell in the kernel
I have noticed, a few posts asking how to disable the console beep/bell on some laptops. While it is possible to disable some applications such as bash, and gnome, you should be able to disable it globally with the kdb command or in /etc/default/kbd. This can already be done for the keyboard click, and should be extended to the console bell. The changes are relatively simple, as adding an option (-b on|off) and code similar to keyclick in /usr/src/cmd/kbd/kbd.c. The appropriate ioctl KBD_CMD_BELL and KBD_CMD_NOBELL are already in sys/kbd.h. Possibly changes may need to made to /usr/src/uts/intel/io/beeper.c (and code for other platforms). Doug P.S. It has annoyed me enought to something about it :) This message posted from opensolaris.org

In the X server, to make a 100ms beep, we do: kbdCmd = KBD_CMD_BELL; ioctl(fd, KIOCCMD, kbdCmd) sleep for 100ms kbdCmd = KBD_CMD_NOBELL; ioctl(fd, KIOCCMD, kbdCmd) You'ld need to add new ones to make a keyboard bell disabling command. (When X is running xset b 0 disables the bell, but there's nothing similar for the console when not running X.) -- -Alan Coopersmith- alan.coopersmith at sun.com Sun Microsystems, Inc. - X Window System Engineering

This will need ARC review so you will need an ARC sponsor was well. Whom ever steps up to be your code putback sponsor can help find an ARC sponsor for you (hint I'm willing to do that bit). -- Darren J Moffat
