How to prevent screen locking when lid is closed?

I have Ubuntu 11.10 with Gnome 3 (no Unity), gnome-screen-saver has been removed and replaced with xscreensaver. The screensaver stuff all works fine -- no complaints there. When I close my laptop lid, even for a second, the screen locks (and the dialog box asking for my password is xscreensaver's). I'd like for this not to happen...

Things I've tried/looked at already:

xscreensaver settings - the "Lock Screen After" checkbox is not checked (though I've also tried it checked and set to 720 minutes)

gconf-editor - apps -> gnome-screensaver -> lock_enabled is not checked

System Settings -> Power - "When the lid is closed" is set to "Do nothing" for both battery and A/C

System Settings -> Screen - Lock is "off"

gconf-editor - apps -> gnome-power-manager -> buttons -> lid_ac && lid_battery are both set to "nothing"

dconf-editor - apps -> org -> gnome -> desktop -> screensaver -> lock_enabled is not checked

I managed to figure out a workaround, though I imagine there's a better solution out there. I looked at what was happening when my lid was closed and opened in /etc/acpi/lid.sh and found that xscreensaver was being called upon automatically. Not sure if different laptops have different settings and whatnot - I really don't know too much about this stuff.

In any case, I tried to make it simply obey its config file and not lock, but couldn't figure it out, so I ended up simply deleting the lines that involved xscreensaver. Now everything works great: no locking, and if the lid is closed passed the amount of time which you have set for xscreensaver to start, it'll start normally (and not lock).

I'm still not sure why xscreensaver is set up to be called automatically when the lid is closed or why it ignores its settings and locks when the lid is opened. I also don't get why with my older laptop this only happens sporadically (sometimes it locks every time, sometimes not at all), despite having the same lid.sh file.

I should also note that I'm using Ubuntu 12.04 with Unity, though I don't think that'll make any difference.
