Yes, after being pushed back from release after release, Fedora 25 finally defaults to using the Wayland graphics stack (assuming you have a supported graphics card). This is perhaps the biggest change to come in the Linux world since the move to systemd. However, unlike that systemd transition, the switch to Wayland was so seamless I had to logout and double check that I was in fact using Wayland.
I called Fedora 24, released earlier this year, “the year’s best Linux distro” but one that I would have a hard time recommending thanks to some ugly kernel-related bugs. Well, Fedora 25 is here with an updated kernel, the bugs appear to be gone, and I have no reservations about recommending it. Not only is Fedora 25 a great release, the updated GNOME 3.22 running on top of Wayland appears to be slick and very stable.
The switch to Wayland has been so long in the making. That being said, I’ve been using Wayland for several years now – on my Jolla devices.
Does anybody know if the non-Gnome spins are Wayland yet, specifically, KDE?
