In Ubuntu 12.04, how can I keep the screen from locking when I close my laptop? I know I can disable locking altogether, but I do want the screen to lock when inactive. And I want it to lock when I suspend. I just don't want it to lock when I close the lid of the laptop.

Do I really have to be the person who sits in a meeting with their laptop lid almost closed?

Specific status for this bug #995840 for Ubuntu 12.04 and 12.10 is listed here under

"When laptop lid is closed screen locks even if it should not."

Current Status is "Confirmed" but the bug is "unassigned"

Is you system completely up to date? Are you using Intel graphics? Do you always get the lock screen when you resume? There was a similar bug reported here:… that is finally resolved in regard to a hang on resume, but includes updates to – G Koe Mar 10 '14 at 21:17
