We have recently learned through the notes of Fedora 25 than the next version of Fedora will bring the graphical server Wayland by default, being perhaps the first distribution to use this graphical server in a stable version.
Today all Gnu / Linux distributions use X.org as a graphical server, something that will change with the new generation of graphic servers, but they are slow to arrive. So Ubuntu is preparing its own server called Mir, a server that is not very popular. However, Wayland is a graphical server that many desktops and distributions are working with but not yet in stable versions or by default in them.
The next version of Fedora will be launched next November 15, if there is no delay. This version will bring Wayland by default, something that they already wanted to offer in Fedora 24 but that for calendar reasons they had to reject and offer it as an alternative in repositories. Fedora 25 will bring it by default although it will make use of Xorg in the programs and functions where Wayland does not have support or operation as is currently the case with Nvidia drivers.
Fedora 25's Wayland will use parts of Xorg when it doesn't work
So we can say that the end user will not have a pure Wayland on his machine, although he should not notice the difference between Fedora 25 and Fedora 23, at least in the graphical aspect, since Wayland offers greater security in the operation of the server and not faster. In other words, end users will only perceive greater security in running applications, but nothing new that Xorg does not offer.
This is great news for the advocates of Wayland, since in the end this graphical server has surpassed Mir, the solution proposed by Canonical, at least in terms of reaching the end user. Now it will be necessary to see if it really the Xorg stable is worth swapping out for Wayland or Mir What do you think?
