guix system: error: more than one target service 'dbus' when attempting to reconfigure sysctl values
Unable to modify desktop services for sysctl tweaks.
This happened after I tried reconfiguring my machine. I added:
(modify-services %desktop-services
(delete gdm-service-type))
(modify-services %desktop-services
(sysctl-service-type config =>
(sysctl-configuration (settings (append
'(("fs.file-max" . "50")
("net.ipv4.ip_forward" . "1")
("fs.inotify.max_user_watches" . "524288"))
%default-sysctl-settings)
To my desktop home configuration. But. After some time the command exits with a
message that's not very helpful:
sudo -E guix system reconfigure ./desktop-system-configuration.scm
guix system: error: more than one target service 'dbus'
I have no other desktop service other than mate-desktop-service-type. This
happens with or without deleting the gdm-service-type. I really don't care
about dbus, but I need the sysctl corrections, does guix have an "idc" flag for
these scenarios? Did I happen to catch a bad commit?
Thanks for your time

Imo the message is very helpful, it is telling you you have dbus service
twice. Dbus service is part of %desktop-services and you've put that twice into
your config according to the snippet. So you have introduced two dbus
services. You need to use just one %desktop-services and modify that,
not use the same list twice. modify-services just takes a list and
returns a modified list, in the first case removing gdm from it,
in the second case modifying sysctl.

Re: guix system: error: more than one target service 'dbus' when attempting to reconfigure sysctl values
Lost a previous email. This is my entire services configuration:
(services
(append (modify-services %desktop-services
(delete gdm-service-type)
(sysctl-service-type config =>
(sysctl-configuration (settings (append
'(("fs.file-max" . "50")
("net.ipv4.ip_forward" . "1")
("fs.inotify.max_user_watches" . "524288"))
%default-sysctl-settings
(guix-service-type config =>
(guix-configuration (inherit config)
(substitute-urls (append
(list
"https://substitutes.nonguix.org";)
%default-substitute-urls))
(authorized-keys (append
(list
(local-file
"./signing-key.pub"))
%default-authorized-guix-keys)
(list (service tor-service-type)
(service mate-desktop-service-type)
(service lightdm-service-type)
(set-xorg-configuration
(xorg-configuration (keyboard-layout keyboard-layout
;; This is the default list of services we
;; are appending to.
%desktop-services))

(modify-services ...))
And calling %my-services instead of %desktop-services below :
;; This is the default list of services we are appending to.
Is this the correct way of fixing this problem? Im guessing there's a good
practice with this.
Thanks to everyone who responded for their time

Hi softwarelibre, On Thu, Mar 20 2025, softwarelibre--- via wrote: > (modify-services %desktop-services > (delete gdm-service-type)) > (modify-services %desktop-services Listing %desktop-services twice here does not look right to me. Would you please share your entire configuration? Kind regards Felix
