When I close my laptop lid and it is suspended, when I open it again it is resumed but without showing the lock screen which is set to come up. It resumes with access to web pages or programs that were left open. I can use my laptop to continue with what I had open for between a few seconds to about half a minute at which point the lock screen will come up. I would much prefer it if the lock screen would show when the lid is opened.
My laptop is a Zoostorm Freedom 10-270 Netbook, with Intel Atom N270 (1.6GHz). It is running Ubuntu 12.10.
