[Bug 1460482] Re: Displays setting not allowing overlay of screens, only cloned and side by side

 

I've found a work-around that at least works in Gnome Classic with
arandr. (Haven't tested it with Unity). Executing the command "xrandr -s
0" before starting or applying the change in arandr gives me the ability
to overlay the screens without it snapping back to side by side when the
setting is applied.  xrandr -s 0 sets the size to size-index 0. I'm not
sure why this seems to override the behaviour of  returning to side-by-
side layout.

Title:
  Displays setting not allowing overlay of screens, only cloned and side
  by side

Status in unity-control-center package in Ubuntu:
  Confirmed

Bug description:
  The "Displays" setting in Unity is not allowing overlay of screens (of
  i.e. different resolution). This used to be possible and does not have
  anything to do with the graphics drivers (it works in XFCE using
  arandr). Using arandr under Unity does not work, though it initially
  allows overlaying the different screens, but when applying these
  settings the screen snaps back to a side-by-side view in the GUI and
  this setting is applied. (Also, if I remember correctly, I was able to
  overlay screens in a upgraded 13.04 installation, but not in a fresh
  install of 13.04.)

  The possibility of overlapping screens of different resolution is
  nice, since for some applications it is good to show only parts of the
  main screen on, say, a projector.

  Regards,
  Tom
