A few weeks ago we reported that future versions of Ubuntu will be shipping with the GNOME desktop, replacing the distribution's custom Unity desktop environment. Following the move to GNOME as the default desktop for Ubuntu 17.10, the project has hinted that Ubuntu will also switch to using the Wayland display server technology. Past releases of Ubuntu used X to power the default Unity 7 desktop and Mir to run the experimental Unity 8 environment. Future releases of Ubuntu are now expected to run GNOME on Wayland as the default environment, a move which mirrors Fedora Workstation's configuration. "Ubuntu is to ship Wayland in place of X.Org server by default. Word of the display server switch won't surprise many. Mir, Canonical's home-spun alternative to Wayland, had been billed as the future of Ubuntu's convergence play. But both Unity 8 the convergence dream was recently put out to pasture, meaning this decision was widely expected. It's highly likely that the traditional X.Org server will, as on Fedora, be included on the disc and accessible from whichever login screen Ubuntu devs opt to use in Ubuntu 17.10 onwards." OMG Ubuntu has more details.
