Bug description:
  On the emulator, many Mir clients are failing to start, with errors
  ranging from

  $ mir_demo_client_egltriangle
  No active outputs found.

  $ mir_demo_client_eglsquare
  error : could not determine display size

  $ QT_QPA_PLATFORM=ubuntumirclient qmlscene test.qml
  Loading module: 'libubuntu_application_api_touch_mirclient.so.3.0.0'
  ASSERT: "displayOutput != nullptr" in file ../../../src/ubuntumirclient/screen.cpp, line 183

  These all suggest the display configuration reported to clients is not
  correct. Checking this:

  $ mirout
  Connected to server: <default>
  Card 0: Max 2 simultaneous outputs
  Output 0: Card 0, LVDS, connected, 480x800+0+0, unused, on, 0mm x 0mm (0.0"), normal
       480x800      60.00*+
  Output 0: Card 0, LVDS, connected, 480x800+0+0, unused, off, 0mm x 0mm (0.0"), normal
       480x800      60.00*+

  which indicates there are no "used" outputs (also the 2 "Output 0"
  entries is suspicious)

  
  To bring up emulator, do:
  sudo ubuntu-emulator create touch --channel=ubuntu-touch/rc-proposed/ubuntu
  ubuntu-emulator run touch 
  and you can connect into is via adb.
