[orca-list] Switching from Gnome to Mate

[Ryan Mann <rmann samobile net>]

Hello.  I am running Ubuntu 17.04.  I installed the Mate desktop by doing apt-get install mate.
I tried to switch to Mate by doing the following:
When the logon screen comes up, press Enter on my name.
Type my password in.
Tab until I get to the menu to choose session.
Press Enter.
I would think this would be a menu, so I up and down arrow.  When I do this, I get no speech.
Since this menu appears not to be accessible, how can I switch the session from Gnome to Mate?
