I recently switched from Gnome to Cinnamon in Fedora 17, and I feel like I did something wrong because it seems as though Cinnamon ignores any Gnome settings, despite being Gnome-based (as far as I understand it). All of the help pages I come across suggest using gconf-editor, dconf-editor, or even the "keyboard settings" to change settings such as the compose key, hotkeys, or the alt+click behavior, but cinnamon ignores anything I change in any of these. I've had to resort to using xbindkeys and running that in a .rc file on startup for hotkeys.
It also seems to ignore anything I put into gnome-session-properties to try to run on startup.
Does anyone know why Cinnamon seems to run just fine but ignore all gnome settings?
