I've encountered the same regression in 12.04. From a bit of digging it seems it's related to the implementation of gnome_rr_output_is_laptop() in gnome-desktop. g-s-d uses this function to determine whether an output is an internal or external display; g-s-d only wants to suspend if there are no external displays in use. The problem is that gnome_rr_output_is_laptop() doesn't work properly in some cases. One case is when the NVIDIA binary driver is present; another recently-fixed case was systems with eDP panels (bug 933710).

There is a patch in bug 949296 that fixes the problem for me (I have the NVIDIA driver case).
