Ubuntu is one of the most popular Debian-based Linux distributions, and it’s undergone a lot of changes. Most recently, Canonical, the developer collective behind Ubuntu, switched from the GNOME desktop environment to an in-house alternative called Unity. But the most recent version of Ubuntu, 17.10, brings back GNOME 3.26.
With GNOME comes GDM (GNOME Display Manager), a tweakable settings menu that replaces Unity’s LightDM. GNOME’s ecosystem makes it arguably easier to customize than the latter — unlike previous versions of Ubuntu, for example, you can change the location of the Windows control buttons (minimise, fullscreen and close) in just a few button presses.
The flip-flop to GNOME follows Canonical’s abandonment of Ubuntu Touch, a phone-optimized version of Ubuntu that used Unity as the default interface, and it’s the first big change to Ubuntu in a while. It’s not the only one: Ubuntu 17.10 has a new default display server, Wyland, that replaces the deprecated Mir (which is now only enabled on Internet of Things (IoT) devices.). Other changes include improved Bluetooth audio playback, the discontinuation of 32-bit ISO images, and a Linux kernel update to the newest version (version 4.13).
Ubuntu 17.10 also marks the second version of the operating system that starts with the letter “A”. Ubuntu’s names are ordered alphabetically, just like Android, and Canonical’s started over again. Ubuntu 17.10 is “Artful Aardvark”.
