Hello Linux Geeksters. As you may know, the initial plan was to use Wayland as the default display server of Fedora 21, along with GNOME 3.14.
Matthias Clasen, one of the Red Hat developers has announced that Flock, a Fedora conference which takes part in the Czech Republic that Fedora 21 will not be using Wayland as default afterall, despite the fact that GNOME 3.14 should be ready to run over Wayland.
But gnome-session-wayland-session package will be available by default, so the users that want to use Wayland as a replacement for X.Org, can install the package, reboot and choose GNOME 3.14 over Wayland, via GDM:
$ sudo yum install gnome-session-wayland-session
$ sudo reboot
While open-source graphics drivers are already available for Wayland, only Intel is creating Wayland compatible GPU drivers, but AMD and Nvidia should do the same, until Fedora 21 gets released. Also, XWayland is working, but 3D hardware acceleration will be implemented only on Fedora 22. For more information, see Christian’s blog post.
