10 Reasons Why GTK2 Still Matters and How Devuan Is Bringing It Back to Life

In an era where GTK3 and GTK4 dominate the Linux desktop landscape, it might seem surprising that a project is actively investing in modernizing the venerable GTK2 toolkit. Yet that's exactly what a Devuan developer has undertaken with 'gtk2-ng'—a fork aimed at injecting modern fixes, security patches, and platform support into the aging library. This listicle explores ten key aspects of this revival, from its technical motivations to its potential impact on the broader ecosystem. Whether you're a longtime user of legacy applications or simply curious about Linux desktop history, these insights reveal why GTK2 isn't ready for the digital grave just yet.

1. The Devuan Connection: Why Systemd-Free Distros Need GTK2

Devuan, a Debian derivative that sidesteps systemd, has long served users who prefer traditional init systems. Many of its supported applications—especially those built for Xfce, LXDE, or older GNOME 2 modules—still rely on GTK2. Without continued maintenance, those apps would face security vulnerabilities, display bugs, and eventual breakage on modern kernels. By reviving GTK2 under the gtk2-ng banner, the Devuan developer ensures that the entire systemd-free ecosystem doesn't lose access to a crucial graphical toolkit. This move isn't just about nostalgia; it's about preserving software freedom without sacrificing stability or security.

2. Modern Fixes for an Ancient Toolkit: What gtk2-ng Actually Changes

The gtk2-ng project doesn't simply recompile the old code—it actively backports fixes from upstream GTK3 and GTK4 branches, addresses long-standing bugs, and introduces new features such as improved HiDPI scaling, Wayland session support, and better font rendering. Other refinements include reduced memory leaks, updated color management, and compatibility with recent versions of Pango, Cairo, and Glib. In short, it transforms a legacy library into something that can run comfortably on a 2024 Linux desktop without requiring a complete rewrite of every dependent application.

3. HiDPI and Wayland: Making Old Apps Look Sharp Again

A major pain point for GTK2 applications on modern displays is their poor handling of high pixel densities. On a 4K monitor, GTK2 apps often appear tiny or require messy environment variables. gtk2-ng addresses this by integrating fractional scaling support and DPI awareness via Wayland protocols. Early testing shows that applications like GIMP 2.10 (still GTK2-based) and Leafpad now render crisp interfaces on hidpi screens. This is a game-changer for users who prefer lightweight tools but don't want to squint at postage-stamp sized icons.

4. Security: Addressing the Elephant in the Room

GTK2 has received minimal upstream security patches since GNOME 2's retirement. That leaves a wide attack surface for buffer overflows, format-string vulnerabilities, and integer underflows. The gtk2-ng fork systematically audits every core component—from GtkWidget to GdkPixbuf—applying fixes from the GTK2-maintained branch in Debian and incorporating additional hardening from projects like OpenBSD. The result is a library that meets modern security standards without breaking binary compatibility.

5. Binary Compatibility: No Recompilation Needed

A core design goal of gtk2-ng is to maintain full ABI and API compatibility with the original GTK2. This means that existing compiled applications—including proprietary software—can simply swap the shared library and gain the benefits. The developer provides a drop-in replacement package, so users on Devuan (and eventually Debian, Fedora, etc.) can install it without touching any application code. This pragmatic approach greatly reduces adoption friction and encourages broader testing.

6. Community Response: Enthusiasm Mixed with Skepticism

Since the announcement on the Devuan mailing lists and the Reddit Linux community, reactions have been polarized. Enthusiasts praise the initiative for breathing life into lightweight desktops like LXDE and for providing a sensible upgrade path for legacy apps. Skeptics question whether the effort is worthwhile when GTK3 offers most features and GTK4 is the future. However, supporters point out that hundreds of applications—from Rox-Filer to Audacious—lack GTK3 ports, making gtk2-ng a practical necessity rather than a nostalgic experiment.

7. Comparison to GTK3 and GTK4: Where gtk2-ng Fits

gtk2-ng is not a competitor to GTK3/4; it's a bridge. It keeps old applications functional while users gradually migrate. In terms of performance, gtk2-ng often beats GTK3 for simple widget sets because it lacks the overhead of CSS styling, animations, and accessibility layers. Meanwhile, GTK4 introduces significant API breaks. By stabilizing GTK2, the project allows developers to postpone a full port without being left behind by security patches or display server changes.

8. Impact on Linux Distributions Beyond Devuan

While Devuan is the primary testbed, the gtk2-ng patches could be adopted by Debian, Ubuntu, and even Arch Linux via the AUR. Debian's LTS and ELTS (Extended LTS) users, in particular, would benefit—many embedded systems and servers still run GTK2-based management tools. The Devuan developer has expressed willingness to submit patches upstream to Debian if the community welcomes them. If that happens, millions of additional machines could see improved stability and security without any re-engineering.

9. Challenges Ahead: Keeping Up with the Ever-Changing Stack

Maintaining gtk2-ng is not a one-time effort. Each new release of underlying libraries (Pango, Cairo, GLib) may introduce breaking changes. The developer must continuously backport compatibility shims while avoiding feature creep. There's also the risk that key contributors become unavailable or that interest wanes. However, the project is structured as a community effort with clear goals, and a small but dedicated team seems willing to carry the torch. The biggest challenge remains funding—volunteer maintainers have limited time.

10. The Future: Could gtk2-ng Spark a New Lightweight Desktop Era?

If gtk2-ng gains traction, it might revive interest in minimal desktops like LXDE or even Xfce's GTK2-based branch. It could also encourage developers of discontinued applications (e.g., gLabels, gPhoto) to resume maintenance. In a world where bloated software is increasingly criticized, a performant, secure, and updated GTK2 stack offers a middle path: modern foundations without abandoning the simplicity that many users cherish. Whether this revival remains a niche effort or becomes a mainstream solution depends on community adoption over the next 12–18 months.

In conclusion, the gtk2-ng project by a Devuan developer is far more than a nostalgia trip. It addresses real needs—security, display compatibility, and binary compatibility—while preserving the lightweight nature that made GTK2 beloved. Whether you're a system administrator maintaining legacy software, a desktop enthusiast seeking speed, or a software freedom advocate, this initiative deserves your attention. The toolkit that powered the early GNOME and Xfce desktops is getting a second lease on life, and the Linux community may be better for it.
