This also happens on my Dell M1330 and is a regression since 11.10 - it is a serious issue since I noticed this as I pulled completely overheated laptop with dead battery out of a bag.
I strongly suggest fixing this before release of 12.04. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-desktop3 in Ubuntu. https://bugs.launchpad.net/bugs/951479 Title: Laptop with nvidia binary drivers does not suspend when lid is closed Status in “gnome-desktop3” package in Ubuntu: Confirmed Bug description: When I close the lid on my laptop (HP EliteBook 8540w), laptop is not suspended. Suspend in other use-cases works ok (e.g. when invoked from system menu). I've done some research and problem is, that gnome-settings daemon thinks that there are active external outputs - in such case suspend is skipped. Have a look at method do_lid_closed_action in gsd-power- manager.c. This method uses gnome_rr_output_is_laptop method from gnome-rr.c to find out, whether output is built-in or external. On my notebook output->name is "default" and hence output is considered to be an external one (even though there are no external outputs connected).
