[Bug 1376618] Re: LightDM Error: (EE) no screens found, after Upgrade from 12.04 to 14.04 (ubuntu 64 Bit) no GUI available

 

AstroPhysik, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal as it will automatically gather
and attach updated debug information to this report:

apport-collect -p xorg 1376618

Please ensure you have xdiagnose installed, and that you click the Yes
button for attaching additional debugging information.

As well, given the information from the prior release is already
available, testing a release prior to the development one would not be
helpful.

Thank you for your understanding.

Title:
  LightDM Error: (EE) no screens found, after Upgrade from 12.04 to
  14.04 (ubuntu 64 Bit) no GUI available

Status in xorg package in Ubuntu:
  Incomplete

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:
