Before you upgraded to Fedora 20, what were you using that was working?

Was that on the same machine you are trying to use now (same 965 Intel video)?

You might get better help asking on a Fedora list, such as the one that can
be suscribed at:

https://lists.fedoraproject.org/mailman/listinfo/users

Have you considered switching to a distro targeted for use by the blind?
Knoppix features Adriane and works well from DVD boot so you can give it a
workout without installing first. http://en.wikipedia.org/wiki/Adriane

I'm just speculating from seeing "UNCLAIMED" above that a required driver is
unavailable, possibly due to having been orphaned in the latest Fedora
version(s).
