Slight correction, it's available in Linux 6.7, and has to be enabled with the kernel parameter nouveau.config=NvGspRm=1
. It may be enabled by default soon though (latest news I could find about that here).

NVK itself is not dependent on anything proprietary, but it's practically required to enable NVIDIA's GSP firmware blob if you want to see actual performance since it's what enables re-clocking (older post by Collabora here which touches on it).
A neat trick I use to figure out what apps belong to what packages is to run realpath $(which $app_name)
- this outputs the full, canonicalized path to the store item, which should include the package name.
I would do a search (e.g. using grep) through a local copy of the Guix repository to figure out what services are providing the packages, then modify the service configurations (or use modified versions of services, if needed) to remove them. This might be a tedious solution, though.
I haven't found a need to do it, but a (modify-services ... (delete pulseaudio-service-type))
in your operating-system
declaration might do what you're asking? I don't think this is necessary though. As far as I'm aware, applications that attempt to use Pulseaudio will be transparently rerouted through pipewire-pulse
, which is already configured by home-pipewire-service-type
. I am also on GNOME, and I haven't noticed any breakage in this aspect using it.
If you're unsure that it works the way you want, you can always try the configuration out and see how it goes (note that I had to re-log in for the wireplumber service to start properly).
I've never tried putting it in the system configuration, but I imagine it wouldn't work as it depends on Guix Home services.
If you haven't used Guix Home before, the home-environment
record doesn't have required fields like operating-system
does so it's fairly easy to get started with.
Here's a minimal working configuration, for example:
(use-modules (gnu)
(gnu home services desktop)
(gnu home services sound))
(home-environment
(services
(list (service home-dbus-service-type) ;home-pipewire-service-type needs this
(service home-pipewire-service-type))))
There is, actually! It's available as a Guix Home service: home-pipewire-service-type
was introduced around the end of December, and you can see documentation for setting it up in the manual.
When using this service, pipewire-pulse
is used by default without any extra configuration.
Cheers, glad to hear you got it working. I don't think there's any problem on your end; all my flatpaks are user-installed as a Guix System user, so it didn't cross my mind that a habitually-placed --user
flag would not work if something was installed system-wide!
Thanks for posting about this! I never thought to try this as an Akregator user, but it's a great idea... I spent the past day getting this to work since I also use the Flatpaks; hope it helps.
As suggested by @progandy@feddit.de, one solution is to define a custom protocol where the URL gets passed to a script that opens Firefox Reader with the URL; here's what I've done:
- Decide on a protocol name, which the URL will be prefixed with and passed to
xdg-open
since that should be available to the Flatpak. I usedfirefox-reader
as the protocol, so I putxdg-open firefox-reader://%u
as the custom command (so a command Akregator would run might look likexdg-open firefox-reader://https://example.com
). - Define a desktop entry to support the custom protocol (you can see mine below).
~/.local/share/applications
is the standard place to put these, as far as I'm aware. Since the custom protocol needs to be removed from the URL, I wrote a script (also below) to do this and then call Firefox withabout:reader?url=
prefixed. The script can be anywhere in$PATH
. - Add the desktop entry as a "default application" for opening URLs using this custom protocol. In my case, I ran
xdg-mime default org.mozilla.firefox.reader.desktop x-scheme-handler/firefox-reader
(org.mozilla.firefox.reader.desktop
is the name of my desktop entry file). - You also might have to update some mime/xdg database stuff. I had to run
update-desktop-database ~/.local/share/applications
soxdg-open
would find the "Firefox Reader" desktop entry.
My Firefox Reader desktop entry
[Desktop Entry]
Type=Application
Name=Firefox Reader
Exec=open-firefox-reader.sh %u
StartupNotify=false
MimeType=x-scheme-handler/firefox-reader;
open-firefox-reader.sh script
#!/usr/bin/env bash
flatpak run --user org.mozilla.firefox about:reader?url="${1#firefox-reader://}"
If you have any other trouble or want to find more information about this since the desktop entry could probably be tweaked, here are the sources of note I used to figure this out (If I forgot a step or two writing this, they should also be present somewhere in there):
I've been having my own fun trying out NVK on Guix System so I can't give you specific instructions (assuming you're not using Guix), but I can tell you what you need and maybe someone else can chip in on how/if you need to do anything else on your distro:
- Linux kernel >= 6.7
- GSP firmware enabled via the kernel parameter
nouveau.config=NvGspRm=1
- Mesa built with the
-Dvulkan-drivers=nouveau-experimental
flag.
A few notes:
- Performance and stability of games has been fairly hit-or-miss for me. Of the 10 Vulkan games I've tried so far: 3 run perfectly, 3 are playable with noticeable issues, and 4 are borked.
- NVK is Vulkan-only, but performance largely comes from the GSP firmware so you will still see a difference (huge for me) in games not using Vulkan.
- You can override flatpaks to use the host's Mesa version (set
FLATPAK_GL_DRIVERS=host
); however, there's a bug that causes the Steam Flatpak to not work when doing this. The mesa-git-extension Flatpak exists which can also be used to replace Mesa runtimes, but it had issues building with NVK so it's currently disabled.
The only package I'm aware of at the moment (other than my hacked-together Guix package) is available in the AUR.
I use git-annex and Guix (particularly Guix Home in this case) for managing all of my data, including dotfiles. git-annex handles syncing (and backups via delivery to a Borg repo) and version management as git does, while Guix takes care of installing programs and setting up configuration files.
I previously wrote a custom Guix service that utilized Stow as well for managing writable files, but have since replaced it with another custom Guix service that handles some cleanup processes better.
Depending on how much you want simplicity of restoration, this approach might be on the heavier side since it's concerned with a lot more than just dotfiles. You could replace git-annex with git to simplify the syncing part if you're only interested in managing configuration files, though. Here's what my Guix config looks like; the readme file shows how I would set up a system from scratch.
Was not aware of this, thanks! Looks like it does, with a notable difference being that Cryptomator has better cross-platform support in exchange for not having file size obfuscation.
You might be interested in git-annex (see the Bob use case).
It has file tracking so you can - for example - "ask" a repository at drive A where some file is, and git-annex can tell you it's on drives C and D.
git-annex can also enforce rules like: "always have at least 3 copies of file X, and any drive will do"; "have one copy of every file at the drives in my house, and have another at the drives in my parents' house"; or "if a file is really big, don't store it on certain drives".
