** Description changed:

  I have an external display attached. When I open system settings in top
  panel right button-> system settings ( or through other approach to
  enter the sub settings directly like time applet-> Time&Date Settings) ,
  the external monitor is disabled for no reason. And after that I click
  the "Display" in system settings, the external monitor is enabled again.
  This combined with other bug(1304531) that move maximized windows around
- makes the open system settings process painful.
+ makes the open system settings process painful. It usually happens only
+ once after reboot, then it is fine.
