I thought it was being started by Shepherd because the process becomes a child of Shepherd after it is auto started. Adding this line to my configuration does help. PulseAudio no longer aggressively starts itself if I stop my pipewire-pulse service. Unfortunately some packages on my system (the primary package that comes to mind I cannot specifically say, but it comes from a different channel) depend on PulseAudio, and will manually start it if it is not running when I start the application. I am hoping for some way to do something equivalent to masking a package in Gentoo[1], so I can avoid having PulseAudio installed at all. I realize something like this might depend on package parameterization[2], but if there is some hacky way to do this with the current version of Guix, suggestions would be appreciated!

Eradicating PulseAudio
Hi, Please help me eradicate PulseAudio from my system. It causes me nothing but pain. My most commonly run commands according to my bash history are pulsemixer followed by pgrep pulseaudio, which I use to debug my audio issues, and pkill pulseaudio followed by herd restart pipewire which I use to resolve my audio issues caused by pulseaudio being started by Shepherd. I don't need or want PulseAudio. The only reference I have to PulseAudio in my system or home config is the following: (service alsa-service-type (alsa-configuration (pulseaudio? #f))) In my system service configuration, with hopes to disable it (unsuccessfully). I use %base-services rather than %desktop-services to avoid the pulseaudio service that the latter includes. How can I transform every package on my system to remove PulseAudio from being an input? How can I stop Shepherd from starting PulseAudio against my will, when there is no pulseaudio service in my home or system configuration? FWIW every package on my system is either installed through my system config.scm or my home config.scm, so I can apply Scheme transformations to every package easily. I also see that there is an issue open to add a PipeWire Home service[1]. I have a very similar service for my own setup that I wrote myself. I skimmed through it, but I cannot see anything that actually stops PulseAudio from loading. Does anyone know if this patch will just resolve my issue? Many thanks, Robby Footnotes: [1] https://issues.guix.gnu.org/63863
Using NoiseTorch with Sway and Polkit
Hi Guix,
I am trying to run NoiseTorch on my desktop, which runs swaywm and
pipewire. I added the following configuration to my system:

Re: Getting Guix to shutdown my laptop properly with Sway and no DE
Hi, I don't have any suggestions for you, I just wish to add that I am also having the same issue, and I use Sway and Elogind (but no display manager). I have been dealing with it by hard powering off also, but it would be nice to have a proper solution :) Robby

I think we may be on to something here. I have an AMD RX 6650 XT, and VLC does also start to leak for me. Guillaume, when you say you forced the video output module to gl, vdpau_display, or xcb_xv, how did you set that? Robby

I tried pinning gstreamer and gst-plugins-base to older versions available in Guix, and removing gst-plugins-base from being an input to OBS (though I'm not positive this removes it from all recursive inputs), but I'm still having the issue :( Here is what I have so far: (let ((parent (specification->package "obs"))) (package (inherit parent) (inputs (modify-inputs (package-inputs parent) (replace "gstreamer" ((options->transformation '((with-version .

Re: Guix home - 'pinning' ?
Hi, > when using guix-home, is there a way to pin a given package to its > current version, so that it stays as it is despite 'guix pull' > bringing new commits ? In your (home-environment (packages ...)) list, you should specify the package that has the correct version that you want. There are two ways to do this. You can either create an inferior channel, and specify the package by looking it up in that channel, or you can apply a transformation to the package to specify the version. Using an inferior package will pull the package from a previous version of Guix - including all of its package inputs. This will pin all of the transitive dependencies of the package as well. See: info guix Inferiors for information on how to define an inferior, and how to select a package from that inferior. If you want to pin a package to a specific commit, version, branch, etc of that package, you can use transformations. See: info guix "Defining Package Variants" for how to use options->transformation, and info guix "Package Transformation Options" for the available options you can set. Hope this helps :) Robby
OBS Studio memory leak
Hi Guixers, For some reason when I use the obs package I quickly leak memory until my system runs out completely, and I have to reboot to resolve it. I had obs-wlrobs, but removing it made no difference. I am able to use the most recent release through Flatpak / Flathub, but ideally I could use the Guix package instead. Is anyone else having this issue? Or could anyone provide insight into how I could resolve this on my system? Thanks, Robby

I am also able to use `,lower` and `,build` on the `plain-file` in the REPL. Building the system with an empty list for the actions works. Maybe this is a bug?

Re: Adding PolicyKit actions
Hi Felix, > Are you using %desktop-services? I am not. I only use %base-services instead. %desktop-services also contains PulseAudio, which conflicts with my usage of PipeWire, so I've added things from %desktop-services as I've needed them. Thanks, Robby
Adding PolicyKit actions
Hello, The root issue I am trying to solve right now is allowing USB redirection to virtual machines. I've tracked down a promising solution here: https://serverfault.com/a/1073230 which involves adding a new PolicyKit action for low level USB access. Digging into the Guix source I was able to find the definition of polkit-configuration (the manual merely mentions that it exists; I may be able to help write more documentation here if I figure this out :) ) and I'm hitting a wall trying to figure out what I am doing wrong. Here is the configuration I have added to my polkit-service in my system configuration: ``` (service polkit-service-type (polkit-configuration (actions (list (plain-file "org.spice-space.lowlevelusbaccess.policy" " http://www.freedesktop.org/standards/PolicyKit/1.0/policyconfig.dtd\;> The Spice Project http://spice-space.org/ spice Low level USB device access Privileges are required for low level USB device access (for usb device pass through). yes no yes ") ``` Looking at the code it looks like `polkit-configuration` has an `actions` field that should be a list of file-like objects, which I think is what my code should be doing. However, I get this error when I build my system: ``` Backtrace: 5 (primitive-load "/gnu/store/avr2qvlgydsvny8dkjl5mvjc0b6?")

I'm not sure why I can't use the system one, but this is good enough for me :). I'm also not actually sure why this works, since I don't have the socket file shown by `libvirtd --help`... Oh well :D good enough for me! Thanks, Robby

If that doesn’t work, try rebooting as well. I had rebooted several times before writing this email, however I just tried `sg libvirt virsh` as my user and that worked... so I tried just running `virsh` and that also worked.

Cannot run virt-manager as my user
Hi,
I am trying to set up virt-manager on my system in order to set up some
virtual machines. I added the libvirtd service to my system by adding
the following service to my system configuration:
```
(service libvirt-service-type)
```
and I've added myself to the libvirt group.
I can see the service running when I do:
```
robby@lambda ~$ sudo herd status libvirtd
Status of libvirtd:
It is running since 10:34:29 PM (5 minutes ago).
Running value is 256.
It is enabled.
Provides (libvirtd).
Requires ().
Will be respawned.
```
I can see the libvirt-sock file that I should be able to use:
```
robby@lambda ~$ groups
users libvirt netdev audio video dialout wheel
robby@lambda ~$ ll /var/run/libvirt/libvirt-sock
srwxrwx--- 1 root libvirt 0 May 28 22:34 /var/run/libvirt/libvirt-sock
```
But I cannot use virt-manager or virsh as my user. I see the following
behavior using virsh:
```
robby@lambda ~$ virsh -c qemu:///system
error: failed to connect to the hypervisor
error: internal error: Unable to get system bus connection: Could not connect:
No such file or directory
robby@lambda ~$ sudo virsh -c qemu:///system
Welcome to virsh, the virtualization interactive terminal.
Type: 'help' for help with commands
'quit' to quit
virsh #
```
So I can use virsh while running as root - but I should also be able to
use it when running as my user...
When I try to connect using virt-manager, I see the following similar error:
```
Unable to connect to libvirt qemu:///system.
internal error: Unable to get system bus connection: Could not connect: No such
file or directory
Libvirt URI is: qemu:///system

Since this seems to be an issue relating to dbus, here are the following
services I have running related to that:
At a system level:
```
(service dbus-root-service-type)
(service elogind-service-type)
```
As my user:
```
(service home-dbus-service-type)
```
Maybe there is some conflict between running dbus as my user and as
root?
Any advice for getting virt-manager working would be greatly
appreciated!
