Tests: 1. reboot normally. Result: gnome-shell is started at the login screen: ps axuww | grep -w gdm root 631 0.0 0.0 296692 3160 ? Ssl 15:04 0:00 /usr/sbin/gdm root 638 0.0 0.1 380308 5840 ?

Test 1 explains the issue originally reported by Ben Greear, that gnome-shell starts due to gdm and is not usable on HW without accelerated graphics: https://lists.fedoraproject.org/pipermail/users/2013-August/440219.html Test 2 and 3 show that gnome-{session,shell} are started at login. The behaviour appears compiled in (not due to a run-time test). The dependency does not appear to be a packaging error.
