Now the you have connectivity and have taken this to the list....  I should tell the list what has been found so far...

As I said, I'm fairly certain you're having problems due to this in your Xorg.log

[    29.862] (EE) [drm] KMS not enabled
[    29.862] (EE) open /dev/dri/card0: No such file or directory
[    29.862] (WW) Falling back to old probe method for modesetting

Looking down further you see it is falling back and using the VESA driver and not nouveau.

[    29.863] (II) Module int10: vendor="X.Org Foundation"
[    29.863]    compiled for 1.14.4, module version = 1.0.0
[    29.863]    ABI class: X.Org Video Driver, version 14.1
[    29.863] (II) VESA(0): initializing int10
[    29.864] (II) VESA(0): Primary V_BIOS segment is: 0xc000
[    29.919] (II) VESA(0): VESA BIOS detected
[    29.919] (II) VESA(0): VESA VBE Version 3.0
[    29.919] (II) VESA(0): VESA VBE Total Mem: 14336 kB

So, that is the problem....   That, I believe, is often caused by another driver being loaded and interfering in things.

It can also be caused by having a parameter set in the boot line....but I see that is not the case as you have...

 [    29.631] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.16.3-200.fc20.x86_64 root=UUID=691db345-e126-4dc7-8846-95545a9422f7 ro vconsole.font=latarcyrheb-sun16 rhgb quiet quiet splash acpi=off

Sooo....

What is the output of "lsmod"?
