hi,
the patch that i've just sent fixes the missing icon and functionality
(on gdm 42.0, have not tested gnome-team branch). I've also added the
at-spi2-core package discussed before. With this gdm logs that the
org.a11y.Bus and org.a11y.atspi.Registry service are started.
However there is a new warning later:
ATK Bridge is disabled but a11y has already been enabled.
I don't really how this dbus service works and if this a problem.
At least the basic stuff like zoom, big text, etc. work. Also I've been
unable to verify that the screenreader/orca starts in the gdm menu
because sound is not working on my machine.
