@Bryce Harrington: The problem parsing the file is another very strange problem, it occurs "sometimes", and other times I can boot normally as right now. By this reason I will try to install Beta 2 (to see if it's something already fixed). I also thought that it was a typo in my xorg.conf but right now I don't have a xorg.conf file in my /etc/X11 directory.
