Create a live usb with F12 or Rawhide ( or install F12 to another HD or partition ) and then copy the xorg.conf.new to /etc/X11/xorg.conf on the live usb and see if that works? If it does you should be able to create the xorg.conf file on your F11 installtion save the file in /etc/X11/ and upgrade as a potential workaround until this issue gets resolved.. JBG
