X session to run browser with Orca from Arch console

[Linux for blind general discussion]

Hi everyone,

Has anybody on the list been able to run an X session from a console in 
order to use something like Firefox plus Orca or Chromium plus Chromevox?

I wanted to avoid having to load all of Mate to do this as efficiently 
as possible.

Any scripts or detailed guidance is most welcome.

Thanks,

Fernando
