Released nine months ago on October 19, 2017, Ubuntu 17.10 was dubbed “Artful Aardvark” by Canonical CEO Mark Shuttleworth because it was the first release of the Ubuntu Linux operating system to ship with the GNOME desktop environment instead of Unity on the Desktop edition. To due to the sudden move from Unity to GNOME, Ubuntu 17.10 brought several substantial changes, such as the switch to the next-generation Wayland display server by default instead of X.Org Server, a decision that was reverted with the release of Ubuntu 18.04 LTS (Bionic Beaver), and the discontinuation of the Ubuntu GNOME flavor.
