GNOME Disks Has Finally Been Ported to GTK4 and LibAdwaita – First Look
It took a few years, but GNOME Disks has been rebuilt from the ground up on GTK4 and LibAdwaita, moving away from the old GTK3/libhandy stack that was used until version 46. As one can expect, the GTK4/LibAdwaita port brings Disks in line with the rest of the standard GNOME apps, offering a modern user experience in 2026.
The main window, drive view, block rows, and all the core dialogs were all ported to GTK4/LibAdwaita. In addition, the disk image mounter and several libgdu utilities (including the restore-disk-image dialog) have been rewritten in Rust. The new Rust-based UI code talks to UDisks2 through udisks-rs, the Rust client package for udisks2.
