  14.04 (ubuntu 64 Bit) no GUI available

Status in xorg package in Ubuntu:

Bug description:
  Hello,

  on 27.09.2014 i did a system upgrade from ubuntu 12.04 (64bit) to ubuntu 14.04.1. LTS (GNU/Linux 3.13.0-36-generic x86_64)
  (A test with the Live DVD 14.04 LTS before the dist-upgrade, was sucessfully.)
  After reboot there was no GUI, only the console. After a login, doing nothing at this state, after some minutes a white screen appears. Seems to be the screensaver.
  Trying tharting the GUI with "startx" there were following errors:
