David, is unity-settings-daemon the only thing that crashes?

Title:
  Touchscreen location incorrect after changing resolution using unity-
  control-center with dual-display setup

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  I have a touchscreen laptop with external display connected.  Both
  support maximum resolution of 4k (3840x2160).  The laptop screen is on
  the left, external display on the right.

  After initial boot from daily xenial live cd 2016-01-17, both screens
  are at the maximum resolution.  When I touch the laptop screen, the
  cursor correctly shows my touch position.

  Using unity-control-center, when I set the resolution of the laptop
  display to 1920x1080, the screen blanks momentarily and apport reports
  that Ubuntu has experienced an internal error.  The resolution reverts
  to 3820x2160 on both screens.  I try again and the screen resolution
  changes properly.  I submitted the report through apport several
  minutes ago, but I don't know how to link it here and I'm not sure
  it's related.

  After the resolution change, the laptop display on the left is
  1920x1080 and the monitor display on the right is 3840x2160.  Touches
  on the left are scaled to the entire width of the desktop, rather than
  under my finger.

  Reverting the resolution to 3840x2160 on both monitors through unity-
  control-center, the touches are still scaled to the whole desktop.  In
  other words, touches on the right side of the laptop display register
  on the touchless monitor.

  When I log out, the touches are correct on the login screen.  When I
  log back in as the ubuntu user with both resolutions at 3820x2160, the
  touch positions are correct.
