He just wants to disable it _on shutdown_, not always.

You seem to be confusing UEFI with Secure Boot.

For me, the greatest benefit of UEFI is that I no longer have to deal
with GRUB.

I wouldn't think that MSWindows would interfere in the UEFI settings and 
enable Secure Boot, but it may have messed up the boot loader settings - esp. 
if the poster had set up the MSWindows boot manager to chainload their Linux 
OS.

From what I have seen there is a conventional BIOS compatibility setting, to 
allow booting vanilla MBR disks.

No, modern PCs don't always have an internal speaker fitted, although the 
MoBos have terminals to connect a piezoelectric speaker to.  They are/were 
useful for BIOS error messages, but I am not sure if modern UEFI firmware 
produces error code beeps when things go wrong - I haven't fitted a speaker to 
mine.

My 6 year old motherboard, according to its documentation (I've never
tried it out), produces a code of beeps when it detects errors such as no
keyboard being found at boot up.  I think no monitor being found also
produces a beep code.  A loudspeaker in the box is the _only_ way a
motherboard has of reporting such errors.

"Modern" UEFI firmware not reporting such errors, if such be the case,
would be one of the reasons for me to depise UEFI as I do.  Why do I need
UEFI?  A traditional BIOS can boot my machine just fine, and the sole
purpose of UEFI seems to be to prevent OS's which aren't Microsoft
Windows from booting, and to brick certain Samsung laptops.

Indeed, on The Register the other day, in a comments sections, somebody
described how he had a dual boot GNU/Linux Windows setup, and after a
Windows update, the GNU/Linux wouldn't boot at all.  He suspected that
the Windows update had tampered with the UEFI CMOS settings somehow.

Do modern motherboards still allow you the option of running under the
traditional BIOS?  I've not seen this mentioned in any of the motherboard
descriptions recently.

The beep speaker in my PC case.

I use XFCE.  I get a similar beep on exiting XFCE, and I've sent a
similar request to an XFCE list asking how I can disable that beep.

Yes, that one!  After spending all the time I did trying to get my
kernel to drive it, I now want to suppress it (sometimes).

hard coded in one of the C files building shutdown itself.  I think I'm
going to edit the source and rebuild it without the bleep.

Hey, that's brilliant!  Thank you very much indeed!  That is an answer
much more complete than I could have expected.

Probably the most satisfactory way for me to make it work the way I want
is to build my own version of shutdown, removing the offending \007 from
that sprintf format string. and then to watch out for new versions
of sys-apps/sysvinit.  The package appears to be relatively stable.

No, no, no!  I don't want to disable my loudspeaker!  For example, I get
beeps through my ssh connection with my ISP telling me that new mail has
arrived.

I simply want to disable that one particular beeping at shutdown time.
(OK, I want to disable the beeping when I click to exit XFCE too, but
I've sent that question to an XFCE list.)

Re: [gentoo-user] Can I suppress the bleep when shutting down?

[Matthias Gerstner]

Hi Alan,

> I simply want to disable that one particular beeping at shutdown time.

well this topic made me curious where the beep is coming from.

It does originate from the shutdown command itself which is part of the
sys-apps/sysvinit package. In this package's source you find can a file
"src/dowall.c", where you will in turn find a function "wall(...)".

This is the function where the warning messages will be produced that
show up in the terminal and the message is produced like this:

snprintf(line, sizeof(line),
"\007\r\nBroadcast message from %s@%s %s(%s):\r\n\r\n",
user, hostname, tty, date);

The "\007" is the beep you're getting. It's a bell character that you
can produce manually by doing this, too:

echo -e "\007"

Unfortunately the bell character is hard coded into the warning message.
Also there seems to be no way to suppress the warning message.

But you could still try is to disable the interpretation of the bell
character by your terminal. Then you could make an alias or wrapper
around the original shutdown command that does this.

According to Arch Linux docs here:

https://wiki.archlinux.org/index.php/Disable_PC_speaker_beep

You can locally disable the bell in the terminal by calling "setterm
-blength 0". But this doesn't work with my terminals. Says it's
unsupported.

Then you can put this in your ~/.inputrc: "set bell-style none". This
works for me. Then, however, all terminals stop beeping. The pcspkr is
still loaded though and can be used.

As you only want to stop the beep only during shutdown you might also be
able to call "xset -b", disabling the bell on the X-server (globally?).
This is not persistent across reboots and you won't have any beeps until
the machine shuts down.

Regards

Matthias

Where is the beep coming from?

Real speakers (like where music comes out) - check Alerts &
Notifications or similar in your DE.

That silly monotone speaker that can only make bing noises and has been
in pc's since the first one?

Is this happening inside a DE session, or from a virtual console?

Eh, you may not know. What if someone is SSH'd in and shuts it down? 
Anyways, disabling this is always the first thing I do when I boot 
ArchLinux.




Can anybody here tell me how to disable this ing annoyance?


I am unfortunately on a Windows box and do not have access to Linux at 
the moment, but there is a kernel module - pcspkr - that causes this. 
You can remove this from your kernel config to prevent it from ever 
happening again. It is also possible to blacklist it, but I'm not sure 
how to do that since I only build in modules for my kernels that I may 
need/are useful.


To test right now, you can 'rmmod pcspkr' and try shutting down.
