Comment 1 Owen Taylor 2009-08-24 11:15:19 UTC 
Intentional, spec file has:

# These are needed to run gnome-shell nested Xephyr mode, but that's a
# developer-only thing and unlikely to be interesting for a normal user
#Requires:       xorg-x11-server-Xephyr
#Requires:       xorg-x11-xauth

Xephyr was a red herring - you really didn't want to run it in Xephyr - it's slow and doesn't really show the experience.

The current behavior is pretty confusing - we should require an explicit command line. Filed that upstream as:

 https://bugzilla.redhat.com/show_bug.cgi?id=518948

As for how to switch, there's a new desktop-effects package in the pipeline 

 https://www.redhat.com/archives/fedora-desktop-list/2009-August/msg00119.html

Until then the best way to try out the shell is
 
 mkdir -p ~/.config/autostart
 ln -s /usr/share/applications/gnome-shell.desktop ~/.config/autostart
 [ Log out and log back in ]

Delete the link to go back to normal GNOME.

There's also 'gnome-shell --replace', but that triggers a bug in Metacity so you don't want to use it (fix also in the pipeline, see:
http://bugzilla.gnome.org/show_bug.cgi?id=588119)
