Comment 1 for bug 1227173

Hi Till, how do you start Onboard? Is it auto-started by the Universal Access setting in gnome-control-center?
gsettings get org.gnome.desktop.a11y.applications screen-keyboard-enabled

Apparently if neither screen-keyboard nor screen-reader are enabled, gnome-settings-daemon may turn a11y off right after login:
(gnome-settings-daemon_:2229): a11y-settings-plugin-DEBUG: screen reader or OSK enablement changed
(gnome-settings-daemon_:2229): a11y-settings-plugin-DEBUG: Disabling toolkit-accessibility, screen reader and OSK disabled

This isn't good for a manually started Onboard, since we need a11y for both auto-show and word suggestions. Hence the dialog asking to turn toolkit-accessibility back on.
