almost got gdm and mate working on archlinux

[Linux for blind general discussion]

I got things up to login and did that and got the screen-saver after that. 
When I ran orca I had sighted assistance looking at the screen and orca 
did not come up talking.  It did show all of its settings on screen 
though.  As a result, I removed mate and mate-extra and orca and brltty 
and dependencies from the system.  I think I'll need to remove whatever 
screen-saver programs gnome and/or mate normally install before turning 
those on next time  Archlinux has orca 3.24 on it if anyone is interested 
in the version of that package that ran that way.  espeak did work before 
gdm started up too so sound and speech on the command line level is 
working.
