Nonguix is a software repository for the
[[https://www.gnu.org/software/guix/][GNU Guix]] package manager,
which packages some software which cannot be included in the official
distribution for ethical or policy-related reasons.
Please do NOT promote this repository on any official Guix
communication channels, such as their mailing lists or IRC channel, even in
response to support requests! This is to show respect for the Guix project's
against recommending nonfree software, and to avoid any unnecessary hostility.
Before using this channel, you should understand the implications of using
nonfree software. Read [[https://www.gnu.org/philosophy/free-sw.en.html][What is free software?]]
for more information.
(Check out the [[https://gitlab.com/guix-gaming-channels][Guix Gaming Channels]]
if you're interested in nonfree games too!)
This channel does not endorse any non-free application.
We believe it is non-ethical, harmful to software development and
restricts the users freedom.
See the [[https://www.gnu.org/philosophy/free-sw.en.html][GNU philosophy]] for a more thorough discussion.
Those packages are provided as a last resort, should none of the official Guix
packages work for you.
You should understand the implication of using non-free software. Some of those
- Endorsement of non-free products and the perpetration of a culture of
restriction on liberties.
- Non-free software cannot (or hardly) be audited: it can potentially spy on
you, destroy or steal your data.
As a minimal security measure, it's heavily recommended to run any non-free
software inside a container.
Nonguix can be installed as a
To do so, add it to =~/.config/guix/channels.scm=:
;; Enable signature verification:

Then run =guix pull=.
* Using Nonfree Firmware and Drivers
To use Guix System with the standard Linux kernel and nonfree firmware, edit
the ~kernel~ and ~firmware~ fields of the ~operating-system~ definition in
;; Import nonfree linux module.
(use-modules (nongnu packages linux)
(nongnu system linux-initrd))
(firmware (list linux-firmware))
If you only need firmware for a specific piece of hardware, you may be able to
save disk space by using a smaller firmware package instead:
(firmware (cons* iwlwifi-firmware
Then of course, run ~sudo guix system reconfigure /etc/config.scm~ to apply
** Installation image
For some hardware the official Guix installation image won't do
(e.g. unsupported wifi). You can generate an installation image running the
nonfree Linux kernel and nonfree firmware with the following command:
guix system image --image-type=iso9660 /path/to/this/channel/nongnu/system/install.scm
Like the official Guix installation image, this will produce a read-only image
with any changes made stored in memory. As indicated below, you will need to
run ~guix pull~ to download the Nonguix package descriptions, so will need
enough memory to hold the cached channel code which can be several hundred
megabytes. As an alternative, you can create a writable image with the
guix system image --image-size=7.2GiB /path/to/this/channel/nongnu/system/install.scm
The ~--image-size~ option allows you to specify the size of the image and, as
such, to allocate free space to it. The given value is purely indicative. It
obviously depends on your thumbdrive capacity.
Either type of image can be written to a USB thumbdrive with:
# NOTE: This example assumes your thumbdrive is recognized by Linux as /dev/sdb.
dd if=/path/to/disk-image of=/dev/sdb bs=4M status=progress oflag=sync
The installation media produced by the above method does not automatically
configure your channels specification. You need to add Nonguix "manually"
into ~/etc/guix/channels.scm~ and then run ~guix pull~ to make Guix aware of
Nonguix scheme libraries. Below is Guile scheme code to include Nonguix in the

** CPU Microcode
CPU microcode updates are nonfree blobs that apply directly to a processor to
patch its behavior, and are therefore not included in upstream GNU Guix.
However, running the latest microcode is important to avoid nasty CPU bugs and
hardware security vulnerabilities.
To enable early loading of CPU microcode, use the ~microcode-initrd~ function
to add the microcode to the Initial RAM Disk. Most users can simply import
~(nongnu system linux-initrd)~ and add ~(initrd microcode-initrd)~ to their
~operating-system~ definition, as illustrated above.
If you need to customize the ~initrd~ for some reason, you should first
understand the upstream documentation on
[[https://guix.gnu.org/manual/en/html_node/Initial-RAM-Disk.html][Initial RAM Disks]].
~microcode-initrd~ simply wraps another ~initrd~ function, which you can swap
out for your own. For example, this:
is exactly equivalent to:
(initrd (lambda (file-systems . rest)
(apply microcode-initrd file-systems
#:microcode-packages (list amd-microcode
** Broadcom Wireless
Some Broadcom wireless hardware requires a proprietary kernel module in
addition to firmware. To use such hardware you will also need to add a service
to load that module on boot, blacklist conflicting kernel modules, and while not
required, it is recommended to stay with Linux LTS releases:
(use-modules (nongnu packages linux))
;; Blacklist conflicting kernel modules.
(kernel-loadable-modules (list broadcom-sta))
(firmware (cons* broadcom-bt-firmware
** Substitutes for nonguix
A Nonguix substitute server is available at [[https://substitutes.nonguix.org]].
On Guix System, you can add and authorize this URL in the following way:
(services (modify-services %desktop-services
(guix-service-type config => (guix-configuration
(append (list "https://substitutes.nonguix.org")
(append (list (local-file "./signing-key.pub"))
Notice that the URL of the server should be specified without a trailing
slash. The file ~signing-key.pub~ should be downloaded directly from
Alternatively, you can replace ~(local-file "./signing-key.pub")~ by:
"<contents of signing-key.pub>")
Guix System will only use the substitution server after it has been
reconfigured. The substitution server will therefore by default not
be used the first time you run ~guix system reconfigure~ after adding
the substitution server. It is therefore recommended to explicitly
specify the use of the substitution server the first time
you reconfigure your system:
sudo guix archive --authorize < signing-key.pub
sudo guix system reconfigure /etc/config.scm --substitute-urls='https://ci.guix.gnu.org https://bordeaux.guix.gnu.org https://substitutes.nonguix.org'
Check out the [[https://guix.gnu.org/manual/en/html_node/Substitutes.html][chapter on substitutes]]
in the Guix manual for more details.
** Pinning package versions
When using substitutes is not an option, you may find
that ~guix system reconfigure~ recompiles the kernel frequently due to version
bumps in the kernel package. An inferior can be used to pin the kernel version
and avoid lengthy rebuilds.
You must pin both Guix and Nonguix, as the Nonguix kernel packages derive from
those in Guix (so changes in either could cause a rebuild). Your preferred kernel
version must be available in both pinned channels.
Consult the output of ~guix system describe~ to get the commits of Guix and
Nonguix for the current generation. Once you have determined the commits to use,
create an inferior in your system configuration file that pins the channels to
them. Then grab the appropriately-versioned Linux package from the inferior to
use as your kernel.
(use-modules (srfi srfi-1) ; for `first'
(first (lookup-inferior-packages inferior "linux" "5.4.21"))))
Contributions are welcome! If there's a package you would like to add, just
fork the repository and create a Merge Request when your package is ready.
Keep in mind:
- Nonguix follows the same
as GNU Guix. If you don't use Emacs, you should make use of the indent
script from the GNU Guix repository (=./etc/indent-code.el=).
- Commit messages should follow the same
set by GNU Guix.
- Although licensing restrictions are relaxed, packages should still have
accurate license metadata.
- If a package could be added to upstream GNU Guix with a reasonable amount of
effort, then it probably doesn't belong in Nonguix. This isn't a dumping
ground for subpar packages, but sometimes we may accept free software
packages which are currently too cumbersome to properly build from source.
- If your package is a game, you should submit it to the
[[https://gitlab.com/guix-gaming-channels][Guix Gaming Channels]] instead.
If you have a history of making quality contributions to GNU Guix or Nonguix
and would like commit access, just ask! Nontrivial changes should still go
through a simple Merge Request and code review process, but Nonguix needs more
people involved to succeed as a community project.
If you want to discuss Nonguix-related topics, you can hang out and stay in
touch on the =#nonguix= IRC channel on [[https://libera.chat/][Libera Chat]].
