Thanks. That info is very helpful.

been added:

So now my question is what is the problem currently? Is that
functionality just not being used by X/gnome_shell? Or is there some
setting that I need to change to enable its use?

Also, would it be possible to have gnome_shell give an error message
indicating what the problem is in these cases?

Thanks,
