Xlibre on GNU Guix

This guide helps you configure Xlibre on GNU Guix.

I install Xlibre now my cat are a werewolf.

This is how I configure Xlibre into my GNU Guix (tested and working):

Modules:

(use-modules (guix ui)
             (xlibre)
             (guix gexp))

Simple Configuration for Xlibre:

;; XLIBRE - Simple configuration
(define my-xlibre-config
  (xlibre-configuration
    (modules (list xlibre-video-amdgpu xlibre-input-libinput))
    (drivers '("amdgpu"))
    (keyboard-layout (keyboard-layout "br"))))

Packages:

(packages
 (append
  (list
   ;; Graphics and Multimedia
   xlibre-server
   xlibre-input-libinput
   xlibre-video-amdgpu
   ;; Custom SLiM service with Xlibre
   (service slim-service-type
            (slim-configuration
             (auto-login? #f)
             (default-user "berkeley")
             (xorg-configuration my-xlibre-config))))
  (modify-services %desktop-services
                   (delete gdm-service-type))))

I removed GDM because SLIM is fast and minimalist.

Custom configuration

Verify your configuration

# Verify available depths and bits per pixel
xdpyinfo | grep -E "depth|bits_per_pixel"

# Verify Xlibre is running with your config
cat /var/log/Xorg.0.log | grep -E "(EE|WW|amdgpu|HDMI-A-0|Screen0|PreferredMode)"

# Check running X processes
ps -ef | grep bin/X

Done!

Many thanks to Space Cadet for packaging Xlibre for GNU Guix. 🗿🍷

@cristiancmoises Welcome and thank you very much for packaging XLibre for GNU Guix! As we take our support of third party packagers serious, I've created a new X11Libre Xlibre On Gnu Guix · Discussions · GitHub and moved this discussion over there. You may reference this discussion category in your repository if you like to. Your repository has also been added to Are We XLibre Yet? · X11Libre/xserver Wiki.

[cristiancmoises]

I am not the creator, developer, or maintainer.
I am just a user who greatly enjoys hacking and free software.
🗿🍷 I'm here to help.

[callmetango]

Thank you!

@cristiancmoises Why did you remove the contents here?

[cristiancmoises]

Incorrect information and it doesn't actually configure Guix to use xlibre...
Just a mistake. When I ran:

ps -ef | grep bin/X

the result was: xorg-server

I fixed it now using the changes recommended by the developer/maintainer.

[smj-cc]

ps -ef | grep bin/X

FYI, this command will find itself. To avoid that you need something like ps -ef | grep bin/[X].

Also, it does not find X on my system, as ps reports it as smj 4137 2.5 0.2 310208 81484 tty7 Sl+ 11:41 6:17 X :0 vt7, as it was invoked through the PATH env var.

[cristiancmoises]

Working now...
