Situation:
After booting my Fedora 19, it displayed a black screen with no possibility of TTY changing. All the processes started properly but I still cannot work with my Fedora.
Main Problem:
It is a bug with the package xorg-x11-server-Xorg.
You can't change TTY because the system retry to load this package on the six available ttys with no success, finally crashing them. You can find more information /var/log/messages on and /var/log/Xorg.0.log
Workaround (not solution):
Downgrade the package xorg-x11-server-Xorg. Use the following command (as root):
yum downgrade xorg-x11-server-Xorg
Download and install the package xorg-x11-server-Xorg-1.14.2-4.fc19. Use the following command:
Reference:su -c 'yum update --enablerepo=updates-testing xorg-x11-server-Xorg-1.14.2-4.fc19'
