Bug Description

When choosing either the screen reader or on-screen keyboard options from the accessibility indicator in the lightdm unity greeter, one would expect the associated applications, orca and onboard to start, however this is not the case. The greeter sets the appropriate gsettings keys, but nothing more occurs. It also appears that at-spi is also not launched.

From some further investigation, I have determined that the session manager launches these applications, based on the given gsettings keys in the relevant desktop files. The unity greeter needs to load these applications itself, however they cannot be hard-coded into the greeter itself, so that people can change the tools they use, particularly in the on-screen keyboard usecase.

So trunk loads onboard correctly (though it is hardcoded right now). Screen reader still isn't done. I'm looking into it.

So it's trivial enough to run orca in a hardcoded capacity. However... keyboard navigation immediately breaks because we aren't running a WM in unity-greeter. Especially once you open the orca preferences and they don't get keyboardfocus. And blind users obviously need keyboard navigation.

So, Robert... How many things would we break if I ran, say, compiz along with orca? We'd have to make the unity-greeter window itself not show window handles... Probably can just make it the desktop window. But do you know of other problems?

Nothing should break but the issues are:
- Putting a hard dependency on the features that compiz needs on startup - so if your GL was broken you couldn't log in
- Potentially slower startup times

I was looking a while back at what it would take to have a minimal functionality inside LightDM. Essentially I think it just needs to set the SubstructureNotify m,ask on the root window and give focus to windows as they are created.
