Re: Disable ugly pc-speaker sound in Slim auth failure

[znavko]

Successfully solved with this code in /etc/config.scm:

(operating-system

...

  (kernel-arguments '("modprobe.blacklist=pcspkr,snd_pcsp"))

)

# guix system reconfigure /etc/config.scm

# reboot

PC speaker no longer beeps. Thank you!

I think it's a luck, cause from here

https://github.com/alezost/guix-config/blob/469db8060235cc6bb7501cfb798f29ede3cc21e6/system-config/os-main.scm#L29

I've got names of kernel modules, so that not only pcspkr, but also snd_pcsp needs to disable

and from here

https://gitlab.com/pkill-9/guix-config/blob/master/system-config.scm#L123

I've got that simple line that not breaks my config.scm syntax.

Still do not know why guix does not find `(use modules (al utils))` module and how to get guile modules work.

You know, Tobias! Just for experiment I've add (al utils) and guix cuss out:

(use-modules (gnu) (gnu system nss)

             (gnu system locale) ;;for locale-definition

             (gnu services desktop)

             ;;(gnu services dns) ;;for dnsmasq

             (srfi srfi-1) ;;for remove function

             (gnu services networking) ;;for remove ntp

             (gnu services avahi) ;;for remove avahi

             (gnu services xorg)

             ;;(gnu services databases);;for postgres

             (gnu packages admin) ;;for wpa_supplicant

             (al utils)

)

# guix system reconfigure /etc/config.scm

guix system: error: failed to load '/etc/config.scm':

ice-9/boot-9.scm:2803:6: In procedure resolve-interface:

no code for module (al utils)

What is wrong here? How to use guile modules?

Mentioned github page has no any use-modules string that can help.

Look again. From system-config/os-main.scm:

(al utils)

And indeed, guile/modules/al/utils.scm has:

(define (comma-separated . strings)

"Return string by concatenating STRINGS with commas."

(mapconcat identity strings ","))

You can copy the definition to your own configuration, or just replace it with the (trivial) MAPCONCAT call directly, or just use a comma-separated string to begin with.

Kind regards,
