fedora 20, on my system, actually works only to line command.

Yes, that is right. The open-source nouveau driver supplied by Fedora
is under heavy development, but in a sizable number of cases it is
still not ready for prime time. Therefore it those cases (like yours)
it makes sense to install the closed-source nvidia drivers, which are
known to work almost faultlessly. The procedure I described installs
those drivers from the rpmfusion repository (which is by far the most
preferred method of instalation).

Ok, this is good.

The log file does not look as I would expect it to --- it indicates that
the nouveau driver is still being loaded. The installation of
kmod-nvidia should automatically disable nouveau and make sure nvidia
driver is loaded instead.

Given that you have installed kmod-nvidia correctly, I do not
understand why nouveau is still active.

It appears that the problem is deeper than just installing appropriate
drivers. It needs more detailed analysis of your system to figure out
what is going wrong.

I am sorry my advice didn't help you. Maybe someone else can chime in
with a fresh idea what might be wrong here.

Best, :-)
