I'm using Fedora 26 and Gnome 3.24, and would like to try Wayland. Wayland seems to be installed, and I've also installed gnome-session-wayland-session. I'm now expecting to be able to choose GNOME on Wayland on the login screen, however I can only choose between GNOME, GNOME Classic and GNOME on Xorg. Finally, GNOME on Xorg definitely doesn't use Wayland since
loginctl show-session 2 -p Type
returns Type=x11. Since Gnome uses Wayland by default, GNOME should use Wayland, however logging in after selecting GNOME gets me back to the login screen...
After trying to log in with Wayland, journalctl -b contains only one line with the word wayland:
/usr/libexec/gdm-wayland-session[1459]: test: Missing argument at index 2
But some lines later many errors related to Gnome appear:

The issue is not hardware related: I've tried to boot on a live USB, and wayland was working.
The system information is
$: uname -a
Linux localhost.localdomain 4.11.11-300.fc26.x86_64 #1 SMP Mon Jul 17 16:32:11 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
How could I use Wayland ?
