Title:
  randr settings fail when i have a virtual crtc

Status in “gnome-control-center” package in Ubuntu:
  Incomplete

Bug description:
  I'm developing fake CRTCs to add new pluggable virtual monitors which can be accessed via VNC.
  it works finde with xrandr. I execute the following commands to set up my multi head environment:
  xrandr --admode VMon 1280x800
  xrandr --output VMon --mode 1280x800 --left-of VGA-0

  Other randr clients such as grandr and gnome-control center crash. I
  dont know why.
