[Bug 1065979] Re: external/internal monitors mirrored on boot when laptop lid is closed

[Iain Lane]

OK, I'll upload this to precise. I have two comments

  - I'd be slightly more comfortable if you took the whole upstream patch
  - Please include patch headers in your uploads so that people looking know how to find out more information. I did that for you this time.

Bug description:
  [Impact]

   * Booting laptop in docking station with lid closed results in low resolution (1024x768/aka clone mode) on external monitor
   * Low resolution desktop (1024x768) when user logs in, must be manually set to optimal resolution for external montior
   * non-technical users would find the default behaviour not the desired behaviour.

  [Test Case]
  Steps to Reproduce:
    1. Connect an external monitor to laptop.
    2. Boot system with lid closed with a clean new user
    3. Login screen is shown at 1024x768 ( the highest common resolution supported by both the displays)

   The laptop display ( say 1366x768)  should have a lower resolution
  than the connected external monitor ( say 1920x1080 ) .

  
  [Regression Potential]
   * I dont see any regression potential here, as this does not change any default behaviour.
   * User must manually activate this "new" behaviour . 

  [Other Info]
   * test packages have been posted to - http://people.canonical.com/~ritesh/work/gsd/
   * Update to this, and update default to "follow-lid"
       $ gsettings set org.gnome.settings-daemon.plugins.xrandr \
         default-monitors-setup "follow-lid"
   * test as usual

  -----------------------------------------------------------------------------------------

  If I put my X220 in a dock, and plug in an external monitor. Then I
  close the lid and turn on the computer, the computer will boot up with
  both the internal laptop screen and external monitor on and mirror.
  Because I can't see the laptop screen, I would expect the external
  monitor to be only on at its maximum resolution. I've actually tried
  this without the dock by plugging in an external monitor to my laptop
  and shutting the lid during boot quickly, the same problem persists.
  This problem is exhibited on Precise/Oneiric as well as Quantal.

  In particular this specification mentions this behavior:
  https://wiki.ubuntu.com/X/Blueprints/MultiMonitor
  In this user story:
  """Alan goes to the office, puts his laptop with the lid closed into a docking station and boots it up. The external display should be run at its native resolution. Later that day he needs to see a customer. He suspends the laptop and takes it out of the docking station. At the customer he wakes up the laptop and the internal screen is used at its native resolution. Finishing his visit the laptop is suspended, brought back to the office. There it is placed in the docking station, woken up and the external display should run again at its native resolution."""
