There is a corner of the open-source world where less is genuinely more, and BunsenLabs Linux has been quietly proving that point since 2015. This week, the community project released BunsenLabs Carbon, its Debian 13-based update, and for users who prize a lightweight, no-fuss desktop, it is worth a close look.
The release comes seven months after Debian 13 "Trixie" landed, which is a little longer than some users might have liked. But the wait has a reason: the BunsenLabs team has used this cycle to swap out several of the distro's characteristic components for Xfce equivalents that can operate on both X11 and the Wayland-based labwc compositor. The default is still Openbox running on X.org, but the groundwork for a Wayland transition is now in place.
The most visible change is the departure of the tint2 panel, a fixture of the old BunsenLabs setup, replaced by xfce4-panel. The lxterminal from LXDE is gone too, replaced with xfce4-terminal. Both substitutions bring practical benefits: the Xfce panel has a built-in graphical settings interface, a step up from the old CrunchBang tradition of opening raw config files in a text editor. Some long-time users may mourn the purity of that approach, but it is hard to argue against a friendlier configuration experience.
Visually, Carbon retains the distro's signature style: a vertical floating panel on the left, no desktop icons, and a Conky system monitor displaying hotkey shortcuts. The app launcher is still the classic CrunchBang-style menu, now called bl-menu. The desktop is stark and functional, with more shading and gradients than its sibling project, CrunchBang++, but still a long way from the visual excess of mainstream desktops.
On resource usage, Carbon is impressively lean. Conky reports roughly 550 MB of RAM in use and the installation takes around 4.4 GB of disk space, which is genuinely compact for 2026. According to The Register, which tested both distros, Carbon actually uses less RAM and less disk space than a comparable CrunchBang++ 13 installation on the same hardware.
The comparison with CrunchBang++ is instructive. That project, largely the work of one developer known as Ben "Computermouth" Young, released its Debian 13 version back in August 2025, well ahead of Carbon. It stays faithful to the original CrunchBang formula: Openbox, tint2, and minimal deviation from what worked before. BunsenLabs, by contrast, has always been the more experimental of the two offshoots, and Carbon continues that pattern. Neither approach is wrong; they serve different users with different priorities.
The one trade-off worth flagging is that the switch from tint2 to the Xfce panel changes how virtual desktops are displayed. Previously, icons for both virtual desktops were visible simultaneously. Now there is a two-number indicator and users must switch between desktops to see what is running on each. It is a minor ergonomic step backward, though the panel's greater configurability may compensate for most users.
For anyone running ageing hardware or simply preferring a desktop that stays out of the way, BunsenLabs Carbon makes a solid case for itself. The project's willingness to modernise without abandoning its roots reflects the kind of pragmatic, incremental thinking that keeps community-driven software alive long after corporate interest has moved on.
