Features

The customizations made to bleUX are abstracted as features, which can be independently enabled/disabled at users' need. The bleux-features package contains all scripts to enable/disable them. At install, the system comes with a set of features enabled by default, and the rest are disabled by default.

The main command to manage features is:

feature <subcommand> <feature>

Core technologies

Package manager frontend

The standard libapt-pkg frontend experience provided by apt can be too low-level and hard to understand. nala provides a more user-friendly alternative, as well as more advanced features that make package managing both powerful and easy.

Feature	Enabled by default	Subcommand to enable	Subcommand to disable
apt		enable	disable
nala		add	remove

Extra subcommands for nala

Subcommand	Description
fetch	Fetches 3 fast mirrors to improve download speed.

Sandboxed package format

As much as snap works really well in embedded environments, its support in desktop environments is average at best. flatpak, on the other hand, is focused on providing the best experience in desktop environments, being supported by the Freedesktop project.

Feature	Enabled by default	Subcommand to enable	Subcommand to disable

Extra subcommands for flatpak

Subcommand	Description
update	Updates applications or runtimes, including related extensions.
remove-unused	Uninstalls unused applications or runtimes on the system.

Audio/media server

pulseaudio is the general purpose audio server developed by the Freedesktop project. Even though, its support is limited in more demanding use cases, such as professional sound producing, where a real-time, low-latency system is required. pipewire not only provides better support for those use cases, but it also handles other types of media streams and aims at being more compatible with flatpak and wayland.

Feature	Enabled by default	Subcommand to enable	Subcommand to disable
pipewire		add	remove
pulseaudio		add	remove

Windowing system / display server

Feature	Enabled by default	Subcommand to enable	Subcommand to disable
wayland*
x11		add	remove

* wayland is not an actual feature. It doesn't have any scripts, as it's already enabled by default.
