Description of problem: I tried to start Cinnamon from pre-Alpha F19 from "gdm" gnome-shell login and it results in a gnome-shell fail dialog with logout dialog instead of a cinnamon desktop. Version-Release number of selected component (if applicable): cinnamon-1.6.7-7.fc19 gnome-session-3.7.91-1.fc19 Steps to Reproduce: 1. yum install @cinnamon to desktop install 2. choose cinnamon from "gdm" 3. login Actual results: gnome-shell fail dialog Expected results: cinnamon Additional info: I am not sure if gnome-session still supports starting non-gnome X sessions now that fallback mode is gone, or this may be something less ominous...
