Hi Maarten - happy to do that, but I need more explicit instructions. Also, I've now seen this happen twice under slightly different circumstances. When I first reported this, I was referring to a situation in which my screen automatically locks after inactivity. To avoid that, I have now changed it so that it doesn't lock, but it does turn off after inactivity and am getting the same behaviour (i.e,. external monitor black, can't do anything on laptop, unplugging monitor makes both go black). I've now had to change to neither lock nor turn off after inactivity in order to maintain a functional system, but obviously this isn't an ideal config.

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.
