I had this working last week, but now it doesn't load the XkbOption from the xorg.conf file. Is there another layer that sets XKB settings that I don't know about?I'm using Ubuntu 13.10, but with xmonad. I load some gnome utilities (gnome-panel, gnome-screensaver, gnome-keyring-demon), but not gnome-settings-daemon.
