Xfwl4 – The Roadmap for a Xfce Wayland Compositor

Original Article

Hacker News Discussion

📝 Discussion Summary (Click to expand)

1. Wayland is the inevitable future – but the transition will be painful
Many users see the move to Wayland as the only viable path forward, yet they also warn that the shift will be slow and fraught with bugs.

“Wayland appears to be the future, and Rust is a good way to help avoid many compositor crashes” – jchw
“The arguments for it have boiled down to ‘yuck code older than me’ … it feels like a regression” – ok123456

2. X11‑centric users fear losing the familiar, lightweight experience
A sizable portion of the community worries that the rewrite will break the “just‑work” simplicity that Xfce is known for, and that the X11 codebase will be abandoned.

“Literally no user cares what language a project is implemented in … we want things to ‘just work’ and not change for no good reason” – coldpie
“I’m a long‑time XFCE user … I don’t think this is accurate. We want things to ‘just work’” – coldpie

3. Technical debate: modularity, performance, and fragmentation
The discussion is split over whether Wayland’s architecture is truly more modular, whether it introduces latency, and how the proliferation of compositors affects stability.

“Wayland is far more modular … it conflates the window manager, the compositor, and the display server” – saurik
“Wayland has been consistently slower than X11 … the compositor will have to render a frame at some point after the VBlank signal” – jchw

4. Funding, donations, and community effort
Users emphasize the importance of financial support for the project and question whether the community is investing in maintenance versus new development.

“If you use Xfce I urge you to donate to their Open Collective” – hu3
“I think a lot of the time people are just writing new code instead of fixing existing things” – uecker

These four themes capture the main currents of opinion in the thread: optimism about Wayland’s future, concern for legacy users, technical trade‑offs, and the role of community support.

🚀 Project Ideas

Wayland Xfce Compatibility Layer

Summary

  • A command‑line tool that automatically configures popular Wayland compositors (Sway, Hyprland, wlroots‑based) to emulate Xfce’s X11 feature set (fractional scaling, HDR, VRR, global shortcuts, focus‑stealing prevention, accessibility, XWayland fallback).
  • Provides a single “xfce‑wayland” profile that users can drop into their session, eliminating manual tweaking and ensuring feature parity.

Details

Key Value
Target Audience Xfce users migrating to Wayland
Core Feature Auto‑configuration and patching of compositors for Xfce feature parity
Tech Stack Bash/Python scripts, libwayland, wlroots, Sway config templates
Difficulty Medium
Monetization Hobby

Notes

  • Xfce users like “I just want Xfce to work on Wayland” (e.g., “I want to keep using Xfce but need HDR and fractional scaling”).
  • Reduces the “feature‑gap” frustration that many commenters mention (e.g., missing xdg‑session‑management, global shortcuts).
  • Encourages adoption of Wayland without breaking existing workflows.

X11‑over‑Wayland Remote Bridge

Summary

  • A lightweight daemon that exposes a Wayland compositor over the network, allowing X11 clients to run remotely via Wayland protocols (similar to XWayland but network‑transparent).
  • Enables remote desktop scenarios where the server runs Wayland and the client runs X11, preserving GPU acceleration and modern display features.

Details

Key Value
Target Audience Remote desktop users, developers testing X11 apps on Wayland servers
Core Feature Network‑transparent Wayland compositor for X11 clients
Tech Stack Rust, libwayland, wlroots, SSH/Waypipe integration
Difficulty High
Monetization Revenue‑ready: subscription (enterprise remote‑desktop service)

Notes

  • Addresses the “no network transparency in Wayland” pain point (e.g., “I want to run X11 apps on a Wayland server remotely”).
  • Provides a modern alternative to X11 forwarding, preserving GPU acceleration and reducing latency.
  • Useful for developers who need to test X11 apps on Wayland without local X11.

Rust Wayland FFI Generator

Summary

  • A CLI tool that automatically generates safe Rust bindings for C Wayland libraries (libwayland, wlroots, smithay) using bindgen and custom safety wrappers.
  • Reduces the “unsafe” barrier that discourages Rust developers from writing Wayland compositors or clients.

Details

Key Value
Target Audience Rust developers building Wayland software
Core Feature Auto‑generated, safe Rust bindings for Wayland C APIs
Tech Stack Rust, bindgen, libclang, Cargo
Difficulty Medium
Monetization Hobby

Notes

  • Responds to comments like “Rust has a massive barrier to C libraries” and “unsafe wrappers are painful”.
  • Lowers the entry barrier for Rust contributors to the Wayland ecosystem.
  • Encourages more Rust‑based compositors and clients, aligning with Xfce’s Rust rewrite.

Unified Desktop API

Summary

  • A cross‑platform library that abstracts over X11 and Wayland, exposing a single API for window management, global shortcuts, accessibility, and session handling.
  • Allows desktop environments to implement features once, regardless of the underlying protocol.

Details

Key Value
Target Audience Desktop environment developers (Xfce, KDE, GNOME, etc.)
Core Feature Protocol‑agnostic desktop API
Tech Stack C/C++, Rust, libx11, libwayland, D-Bus, AT‑SPI
Difficulty High
Monetization Revenue‑ready: subscription (enterprise desktop tooling)

Notes

  • Solves fragmentation issues (“different compositors need different protocols”) and the “missing xdg‑session‑management” frustration.
  • Enables rapid feature parity across X11 and Wayland, reducing maintenance overhead.
  • HN users who want a single codebase for both protocols will appreciate this.

Wayland Performance Optimizer

Summary

  • A daemon that monitors compositor performance on low‑end hardware and dynamically tunes settings (buffer usage, underlay/overlay, atomic commits, frame pacing) to minimize input‑to‑pixel latency.
  • Provides real‑time diagnostics and auto‑tuning for users who experience lag on older machines.

Details

Key Value
Target Audience Users with older hardware or high‑latency complaints
Core Feature Auto‑tuning compositor settings for low latency
Tech Stack Rust, libdrm, libwayland, systemd‑path, D-Bus
Difficulty Medium
Monetization Hobby

Notes

  • Addresses the “Wayland is slower” and “input lag” concerns raised by many commenters.
  • Gives users a simple “opt‑in” tool to get the best performance without manual tweaking.
  • Encourages broader adoption of Wayland on legacy hardware.
