Hi Maarten,

Our QA couldn't reproduce the issue here, Paulo couldn't reproduce the
issue as well. I tried with IVB, eDP+HDMI and couldn't reproduce.

Then I went to our lab and got a SNB with LVDS and DP, installed a fresh
14.04, configured the external monitor to the left side and waited 5
minutes and also couldn't reproduce the issue. after 5 minutes it is
lock and black and after I move the mouse everything just light up and I
can normally log in.

On launchpad bugzillas I've seem people reporting the issue with non intel gpu.
or with hibrid using fglrx.

Please provide more info here. Can you double check if this happens even
without hibrid and without the fglrx driver and provide the logs?

Thanks,
Rodrigo.

  Log in not available after lock screen with multi-monitor

  Confirmed

Bug description:
  After the screen locks I am unable to log back in because the screen
  with the login prompt is black, and the screen on my laptop just shows
  the Ubuntu logo.

  Furthermore, if I then unplug the external monitor (in an attempt to
  force the log in option to be displayed on the laptop)  the laptop
  screen then goes black and I can't do anything at all.

  I can't reproduce this if I select "lock screen" from the UI, but it
  happens reliably if it locks due to inactivity.

  Other info:
  - I am running a fresh install of 14.04
  - I have it set to lock after 5 min of inactivity, and require login after lock
  - I have an external monitor, configured to be on the left side of the laptop screen
