        <pre>Copied from launchpad.

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</pre>
