apport information ** Tags added: apport-collected trusty
** Description changed: 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 + --- + ApportVersion: 2.14.1-0ubuntu3 + Architecture: i386 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC1: jane 2184 F.... pulseaudio + /dev/snd/controlC0: jane 2184 F.... pulseaudio + CompizPlugins: [core,composite,opengl,compiztoolbox,decor,vpswitch,snap,mousepoll,resize,place,move,wall,grid,regex,imgpng,session,gnomecompat,animation,fade,unitymtgrabhandles,workarounds,scale,expo,ezoom,unityshell] + CurrentDesktop: Unity + DistroRelease: Ubuntu 14.04 + HibernationDevice: RESUME=UUID=61f52096-031e-4e3d-b1ae-e504b3b3edec + InstallationDate: Installed on 2014-05-01 (20 days ago) + InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release i386 (20140417) + MachineType: Dell Inc.
