Was at a meeting today and at some point a whole side of the table was lined with half-closed laptops - except one that was closed fully. You could play "spot the GNOME 2.x user" (hello, Richard). That is because GNOME 3 on Fedora 16 has a reliable suspend, so everyone has it enabled by default, because that's what one normally wants. At a meeting, people used to close the tops to direct their attention to the presentation, or to indicate that they do. But that was then. Now, doing so triggers suspend, and that bumps you off VPN or weird WiFi providers like BitBuzz. Result is funny-looking and awkward. My neighbour eventually resorted to locking the screen (which blanks) instead of closing the top. Although blocking the distraction effectively, this has the disadvantage of not sending the right signal to the presenter, but tough cookies.
I think ideally I might like some kind of hotkey-suspend or whatnot, and disable suspend-on-close, but I dunno. Seems kind of bothersome to RTFM for GNOME. Worse, getting everyone in a meeting to agree on upon a non-default configuration seems like a non-starter.
