@xnox,

If we do nothing for ubiquity-dm, the background issue will be introduced after unity-settings-daemon is patched.
This is why the background issue is not mentioned in the beginning.

 - pulling 'feh' from universe/graphics is bad if we can find out other solution to fix the background issue.
 - disabling the background usage of unity-settings-daemon / gnome-settings-daemon is bad if we can fix the background issue of u-s-d/g-s-d that uses libgnome-desktop to render the background, and, so far as I know, GNOME doesn't maintain this way to render the background for HiDPI. GNOME desktop use GNOME shell service to render the background now so GNOME desktop works fine. 
 - using above to "fix ubiquity wallpaper" is bad, but I can not find a better solution so far.

There are also some other issues, such as the abnormal position of
indicator applets, the randomly abnormal size changing of the ubiquity
window content, and the randomly abnormal position of the ubiquity
window.

The window manager that ubiquity-dm used is metacity instead compiz so
there are also some issues here for HiDPI.

If possible, I hope Desktop team can put more resources to fix HiDPI
issues in ubiquity/unity-greeter/unity-settings-daemon directly.

Title:
  Account creation during first boot of an OEM image needs to scale
  based on resolution

Status in OEM Priority Project:

Bug description:
  [Impact]
  The ubiquity window size display in HiDPI screens is small.

  The new gSettings to scale GTK applications (and their corresponding
  settings in System Settings) work great, but this does not help for
  the account creation (first boot) for users buying a pre-install
  system.

  We would need changes in Ubiquity to:

   * Probe the monitor to get resolution information
   * Re-scale the ubiquity window using the corresponding gsetting (com.ubuntu.user-interface scale-factor) based on resolution

  We would need the changes to be backported to Trusty as well.

  [Test Case]
  1. Install image on a system with HiDPI panel
  2. Check the ubiquity window size displayed on screen

  Expected Result:
  The window size should be reasonable for user to read the content.

  Actual Result:
  The window size is small and user is hard to read the content.
