XFCE (originally "XForms Common Environment", though it no longer uses XForms) is a lightweight, modular desktop environment built on GTK. Its design philosophy prioritises speed, low resource usage, and modest hardware support: a modern laptop running XFCE has a smooth, responsive experience, and even old or underpowered machines remain usable with it.

XFCE is traditional in its interface: a taskbar at the top, a panel or dock at the bottom, a menu button with categorised applications, a file manager (Thunar) that feels familiar to users of Windows Explorer. It is the desktop of choice for people who miss the GNOME 2 style, for lightweight distributions (Xubuntu, Manjaro XFCE, Linux Mint XFCE, MX Linux), and for older hardware where GNOME or KDE Plasma would struggle.

Under the hood, XFCE is built from discrete components that can largely be swapped in and out: xfwm4 (window manager), xfce4-panel (panel), Thunar (file manager), xfdesktop (desktop and wallpaper), and a range of plugins and utilities. This modularity is part of its appeal—change one piece without disturbing the others.

XFCE has so far remained X11-based, though Wayland support is in progress and expected in future releases. For now, if you want a lightweight desktop that reliably works on any hardware, XFCE is a safe and well-supported choice.
