Adding 'single' to kernel boot line in grub, I was able to boot in a text-mode terminal. From that, I did 'rm /etc/X11/xorg.conf/ and reboot. System boot and load until the Gnome Login Screen, but after I wrote the password the system hangs on the login screen. After about 15 second, on the screen appears the 'Something has gone wrong' picture and all stuck.
After many attempts on this issues, I did: on a single mode terminal, yum -y remove @gnome-desktop yum clean all yum -y install @gnome-desktop yum update the kernel was also updated to Kernel (3.14.3-200.fc20.x86_64) 20 (Heisenbug) and now the system load the gnome environment and seems ok. On loading screen remains the same issue about UEFI: [ 0.599986] EFI: Problem loading in kernel X.509 certificate (-129) in yellow.
