The system configuration for %systemchoice "desktop" ( ... set in config.scm) has been tested via guix system build:

and successfully builds every package, module, and service - including Nvidia Drivers.

Update [10.2.26@17:04]: Pinned the commits of the Guix and Nonguix channel, so now we have valid substitutes available and can build packages like steam-nvidia and the full linux kernel.

This GNU Guix Configuration pre-configures a few useful channels to make certain Packages available that are otherwise missing in the official GNU Guix repository, these include:

• nonguix, this channel provides nvidia drivers, firmware, and a full Linux kernel.
• jonabron, this channel provides games, emacs packages, window managers, discord, and more.
• emacs, this channel provides melpa emacs packages.
• guix, this is the default and official guix channel.
• pantherx, this channel provides various packages. [Currently Disabled]

Clone this repository via git clone https://github.com/nixpup/geex, then move the files to their respective destinations:

• cp channels.scm ~/.config/guix/channels.scm
• cp channels.scm /etc/guix/channels.scm
• cp -r files /etc/guix/files
• cp -r systems /etc/guix/systems
• cp home.scm /etc/guix/home.scm
• cp config.scm /etc/guix/config.scm

Don't forget to import the Nonguix Key via sudo guix archive --authorize < /etc/guix/files/keys/nonguix.pub, as well as the panther key via sudo guix archive --authorize < /etc/guix/files/keys/panther.pub.

Then you can update Guix and its Channels by invoking guix pull, and afterwards check whether all Channels were correctly set up with guix describe. Make sure that ~/.config/guix/channels.scm is the first item in your "$PATH".

Update Bash's Guix binary and configuration with hash guix after guix pull is done.

Afterwards, you need to pick your systems configuration. For that, edit the /etc/guix/config.scm file and change the "%systemchoice" variable, for example like this:

(define %systemchoice "desktop") ; Available options: "desktop", "laptop", "minimal", "libre".

; ... rest of the File.

This will then pick one of the following systems files:

• "desktop" -> /etc/guix/systems/desktop.scm
• "laptop" -> /etc/guix/systems/laptop.scm
• "minimal" -> /etc/guix/systems/minimal.scm
• "libre" -> /etc/guix/systems/libre.scm

The main difference between these systems configurations, is that the Laptop configuration does not come with Nvidia Drivers, unlike the Desktop Configuration. The minimal configuration has as little packages, services, and options set as possible, while still maintaining a proper working system. While the libre configuration does not come with nonguix, and ships the default GNU Guix linux-libre kernel.

To apply the system configuration, run sudo guix system reconfigure /etc/guix/config.scm. Similarly, to reconfigure or apply the Guix Home configuration, run guix home reconfigure /etc/guix/home.scm.

If you copied all the files of this repository to their respective target directories, you can test the Guix Home environment this configuration sets up for you inside a container via guix home container /etc/guix/home.scm. This gives you a minimal environment with only the packages, configuration files, variables, and settings provided by the home.scm file.

You can run a dry-build of the entire Guix System via guix system build /etc/guix/config.scm. This will build the entire system configuration, but not install it anywhere. You get a resulting /gnu/store path for your built system. This is useful to check whether the system configuration you wrote actually works/builds correctly, before running into issues when you're trying to install on real hardware/bare metal.
