It is still an issue in 12.04!
After an update several days ago my Dell E6520 with the intel CPU built in
graphics does not suspend when an external display is attached and I close the
lid. It suspends from the power menu and also on lid close id there is no
external display attached.
Before the update suspend on lid close worked fine even if an external display
was attached.
Unfortunately I can not tell which upgrade is responsible for the change, but I
can tell, that I reboot the mashine every weekend and I upgrade every 2-3 days.
That's why I think the upgrade responsible for the change arrived in the last
week, somewhere between 2012.05.21-2012.05.28.

Title:
Laptop does not suspend on lid close when external display is
connected
Status in “gnome-settings-daemon” package in Ubuntu:
Confirmed
Bug description:
I've configured my laptop to suspend when the lid is closed (in gnome-
control-center's Power panel). It works ok as long as there is no
external display connected. However when I connect my external LCD,
laptop IS NOT suspended (external display is turned off though).
I've done some research and found out that problem is in gnome-
settings-daemon package: There is code in gsd-power-manager.c in
do_lid_closed_action function which checks whether there are any
active external outputs and if it finds any, it prevents suspending. I
believe that in this case we should honor what's set in gnome-control-
center and suspend. Patch which removes this logic is attached.
