Hello Linux Geeksters. As you may know, all the Linux systems use the good old X.org as the default graphical server, but Canonical and Red Hat want to change this.
Canonical has decided to develop its own graphical server, called Mir, because they wanted to have full control over Ubuntu Touch’s display server, this representing a big piece in achieving the long awaited convergence. On the other hand, Red Hat also wanted to bring something new on the market and developed Wayland, yet another display server.
For now, Mir is used only on Ubuntu Touch (along with Unity 8) and does not have support for proprietary graphics drivers. Wayland should be used by default in the future Fedoras, most probably starting with Fedora 22, which will be released this year.
But if you want to test Wayland on your Ubuntu 15.04, all the needed packages are available via PPA, so all you have to do is add the ppa to your system, update the local repository index and install the needed packages. Like this:
$ sudo add-apt-repository ppa:wayland.admin/daily-builds
$ sudo apt-get update
$ sudo apt-get install xwayland weston
For Ubuntu 15.04 GNOME, also install the gnome-session-wayland package:
$ sudo apt-get install gnome-session-wayland
To revert the changes from both Ubuntu 15.04 (Unity) and Ubuntu 15.04 GNOME, do:
$ sudo apt-get install ppa-purge
$ sudo ppa-purge ppa:wayland.admin/daily-builds
