Dep chain audit showed winit, iced_winit and iced_tiny_skia all had
"x11" in their default features. Even though our Wayland-only build
doesn't use any X11 code path, the defaults were propagating through
cargo feature unification — winit-x11, tiny-xlib, x11-dl, etc. were
all being linked.
Fix, at the dep declaration level:
- [dependencies.iced_winit] default-features = false + wayland/wayland-dlopen
- [dependencies.iced_tiny_skia] default-features = false + wayland
- iced submodule's workspace winit = { ..., default-features = false }
Result on cosmic-yoterm binary:
- size: 55.4 MB -> 53.8 MB (-1.6 MB, ~3%)
- winit symbols: 2151 -> 1340 (-811)
- x11 symbols: 1526 -> 503 (-1023)
Remaining x11 footprint (~500 symbols):
- clipboard_x11 / x11rb: window_clipboard pulls both x11 + wayland
backends unconditionally on unix targets. Would need forking
window_clipboard to gate x11 behind a feature.
- tiny-xlib / as-raw-xcb-connection: low-level window-handle bindings
pulled by wgpu/softbuffer even when no X11 windows ever exist.
Dead code at runtime, probably best left alone until wgpu/raw-window-handle
upstream make these optional.

LIBCOSMIC
A platform toolkit based on iced for creating applets and applications for the COSMIC™ desktop.
Documentation
- API Documentation: Automatically generated from this repository via
cargo doc - libcosmic Book: A reference for learning libcosmic
Templates
- https://github.com/pop-os/cosmic-app-template: Application project template
- https://github.com/pop-os/cosmic-applet-template: Panel applet project template
Dependencies
While libcosmic is written entirely in Rust, some of its dependencies may require shared system library headers to be installed. On Pop!_OS, the following dependencies are all that's necessary to compile a typical COSMIC project:
sudo apt install cargo cmake just libexpat1-dev libfontconfig-dev libfreetype-dev libxkbcommon-dev pkgconf
Examples
Some examples are included in the examples directory to to kickstart your COSMIC adventure. To run them, you need to clone the repository with the following commands:
git clone --recurse-submodules https://github.com/pop-os/libcosmic
cd libcosmic
If you have already cloned the repository, run these to sync with the latest updates:
git fetch origin
git checkout master
git reset --hard origin/master
The examples may then be run by their cargo project names, such as just run application.
