A clarification: when I say the bug does not occur when the laptop lid
is open, I should have added the important proviso that the laptop LCD
panel should be an active display in addition to the external monitor.
That is, both displays must be displaying the desktop. It is not
important  which mode is used, i.e. whether "Same image in all monitors"
is checked in the Gnome Monitor Preferences or not.

If the lid is merely open but the laptop LCD is powered off, the bug
occurs.

** Summary changed:

- [Natty,Maverick,Lucid] External monitor connected w/ Display Port power management not working when laptop lid closed
+ [Natty,Maverick,Lucid] External monitor connected w/ Display Port power management not working when laptop LCD powered off
