Changes

<google>RHEL6BOX</google> The Display Preferences dialog also provides the option to change the orientation of the desktop to match the orientation of the monitor. This is achieved using the Rotation control. This setting can be used to orient the desktop such that it will appear the right way up if the monitor is physically upside down or on its left or right side. If you are feeling brave, try changing the setting to upside down mode while your monitor is still the right way up. Once the desktop is upside down, revert to the Normal setting, keeping in mind that the mouse will move up when you move it down, left when you move it right and so on.
