You probably already know many of Ubuntu 17.10’s new features as we blogged about them during its six-month development cycle. The first thing users will notice when running Ubuntu 17.10 is that their beloved Unity user interface is gone, as it’s been replaced with the GNOME 3 desktop environment. Running on top of Wayland, GNOME 3.26.1 is being used as default session, making the Ubuntu GNOME flavor obsolete. That’s right, Canonical decided to adopt the next-generation Wayland display server too, putting the X.Org Server session on the back seat, as a fallback for PCs whose graphics cards do not support Wayland.
