The reason seems to be that the nouvaux driver is not getting loaded 
properly???
To wit:

# lsmod | grep nouveau
#
# modprobe nouveau
modprobe: ERROR: could not insert 'nouveau': No such device

# insmod 
/usr/lib/modules/3.16.3-200.fc20.x86_64/kernel/drivers/gpu/drm/nouveau/nouveau.ko
insmod: ERROR: could not insert module

nm -u 
/usr/lib/modules/3.16.3-200.fc20.x86_64/kernel/drivers/gpu/drm/nouveau/nouveau.ko

outputs 348 unresolved symbols, the relevant missing ones are shown by 
dmesg:

And I have no idea which acpi module has the function acpi_video_get_edid().
I do not have the kernel full sources. I guess I could download the source
when I am at a high speed hotspot.

None of this was a problem when I installed fc20 from iso.

I have uploaded the relevant lines from Xorg.0.log  to
https://www.sendspace.com/file/3az46j

so you can see the attempt to load the drivers.
