If you have nVIDIA cards, you can now easily run GNOME on the top of Wayland for fun, curiosity or for filling bugs. Obviously, we are going to use the open source drivers (Nouveau), which come pre-installed and they are the default in every Fedora/nVIDIA installation.
First you need to grab a copy of Fedora 21 workstation from Koji
I won’t guarantee anything here, but in my case the Rawhide image (v20140522 64bit) got installed smoothly aside with Ubuntu on the same disk (UEFI). Next, you need to install the Wayland session and the dependency packages (xorg-x11-server-Xwayland).
$ sudo dnf install gnome-session-wayland-session
That will add the GNOME on Wayland option on the GDM, and then you can just choose it and run it with none additional hassle as it was happening in Fedora 20.[caption id="attachment_26401" align="aligncenter" width="640"] GNOME on Wayland with nVIDIA and Open drivers[/caption]
The truth is that Wayland session (at least with nVIDIA) is unusable at the moment. For example among other bugs we can’t move CSD’s windows. However there are huge huge improvements on GNOME Shell 3.13.2 (typically Mutter 3.13.2), that is going to be released tomorrow (May 28) and it will be included in Fedora 21 in the next couple of days.
Anyway, if you have a spare partition and spare time, just give a try. You will also love the very improved Anaconda, which is an excellent work from Fedora engineers, even if it is far from complete!
